The Lot-O Used To Be My Favorite Tumbler. It's Not Now. See Description Below.

[@dreamlookautodetailingauto3353]

Hi Rob, I finally received my long-awaited Lot-O, after months on back order... From some of the horror stories I've heard of the motor, I sure hope it lasts. I did find out that moving the dowel towards the barrel did indeed improve the performance. Runs like a champ! Awful of the manufacturer not correcting this & leaving it up to us to fix?! Again, I thank you for your time & great instructional video to correct this problem & others that may arise. Glad we have you as a teacher! Blessings to the family. Go Blue!

[@MichiganRocks]

I'm glad you finally got one! Both of my newer motors are still running fine, so hopefully yours last too. I've heard rumors that the motors they're currently using might be better.

[@mjoyparks]

This video is amazing! So many tips, like the PVC pipe to balance the barrel, not using plastic in the vibratory, the rubber band seat belt, dampness, fill level, and on and on. Thanks for sharing all of your tips from years of using a vibratory tumbler. In combination with the rotary vs. vibratory video I believe you have answered all my questions and musings about tumbling!

[@MichiganRocks]

I'm glad you found it useful, Maggie. It always make me feel good when I find out I helped someone.

[@KevBoneT]

@@MichiganRocks You Should feel good. You help people and bring them joy. Good job, big guy.

[@MichiganRocks]

I'm curious too. I have a few things planned out, but the rest will be a surprise to me too!

[@gwynnfarrell1856]

Thank you for showing the whole process! Since acquiring my Lot-O, I've been thrown off track getting to use it by selling my house and surgery, you know, life! Now that I'm getting back on track this is going to be really helpful. You answered a whole bunch of questions I've had about it. I'm going to watch the video again and take notes this time. The used Lot-O I bought has the dowel set where you recommend and I'll be listening to its sound and will know better about the condition of the motor. I've had a bowl of agates ready for the Lot-O for over a year now. Can't wait to get to it! Thanks again, Rob!

[@MichiganRocks]

You're welcome, Gwynn. I'm glad your life is getting back to normal and that you're finally going to get those agates done. Good luck!

You're welcome, Suzann.

[@kellylemon4860]

Just had to drop a HUGE thank you for this awesome video on the Lot-O Tumbler! Including the visual of how to move the dowel for better action was a total game-changer! I've watched all your videos more times than I can count, and without you, I'd still be tumbling stones like a complete novice! Your videos seriously "rock"! - please keep them coming! Thanks again for helping me with my skills and for making my rocks shine!

[@ricksmith1647]

I got a Lot O for Christmas and had the same problem. People on the Rock Tumbling Hobby Forum (including you) suggested moving the dowel and it made a big difference. I'm just glad that I knew from watching your videos that mine wasn't adjusted right.

[@MichiganRocks]

I'm glad you were able to get it figured out. Is the Rock Tumbling Hobby a great place to get good advice?

I'm glad I watched this video. I recently started using a Lot-O twin barrel vibratory tumbler, and I noticed the action didn't seem right (it didn't look like the action I've seen in your other videos). I may need to move the dowel. I'm glad to see others in the comments here have done the same and had positive results.

[@MichiganRocks]

Just be careful not to move it too far. It can break springs if the action gets too violent.

[@MariaInIowa]

I have had my Lot-O for a couple of years and never got the motion of your original. Amazed to learn about tuning them! I will adjust the fulcrum point on mine. I bet it makes a huge difference. Thank you!

[@MichiganRocks]

Good luck, Maria.

[@kjellsvensson9621]

Thank you so much for putting out this video. I couldn’t figure out why I wasn’t getting the results I wanted. I noticed how the rocks in your Lotto really were moving faster and couldn’t figure out how to make the change. Moving the dowel seems to have made the difference!

[@MichiganRocks]

Worked for me!

[@LanceDean]

Rob, excellent Lot-O overview video. I will say I purchased my Lot-O a couple of years ago based off of your work. It seems every single Lot-O is slightly different. I didn't fill my block base before painting and mounting and instantly regretted it. The base needs density more than weight for action sake. I placed railroad rail pieces in the block base and that added density helped action tremendously, so I'm glad you filled your holes. I put an old solid rubber doormat under my block between it and the concrete shop floor. Also, I found the use of a fine mesh sink drain strainer helps me drain the water without losing small ceramic pieces between my fingers, it fits over the mouth perfectly. I have a video on it here. I also discovered upon advice from another Lot-O user that my action works best if I give the bowl a slight, less than level, forward towards the motor tilt. Thanks for all your videos!

[@MichiganRocks]

Hi Lance. One thing that I have noticed is that if you put two of them under your stairs like I did, the noise is more noticeable. You can sort of hear and feel it on the far end of the house upstairs. It's still not loud, but more noticeable than with just one. I have always had a folded up towel under mine. Since buying this second one, I bought some foam blocks designed for noise isolation. They didn't help at all. Now I have bubble wrap wrapped in the towel and placed under the block. I don't think that helped at all, but I left it under there. I have used the strainer like you mentioned, but I worry that grit will get stuck in the rim around it and contaminate my batch. I drop a few between my fingers, too, but I keep doing it that way because I can be sure my hands are well rinsed. That's the first I've heard of slanting the barrel. I'll have to try that.

[@jaredyoung5340]

Thank you for making this video! I bought a double barrel last fall. After watching your videos on using it I did notice how different the roll speed was between yours and mine... I was almost to the point where I was getting self conscious about it! One thing I noticed with the double barrel is that over time the fans had come out of alignment thus causing one side to be less vigorous. But anyway, great review!

[@MichiganRocks]

I have never had my fan weights get out of alignment, but it's good to know it's something to look out for.

[@chasd896]

I purchased a twin Lot-O-Tumbler in the Spring and ran about 12 loads of stone when I noticed some differences in the tumbling speed compared to your videos and my own machine. The left side tumbled faster than the right side. I also had the left side fan come off during a session while I was asleep. I sent an email to the Lot-O-Tumbler folks with an attached video. The video showed a wobbly spin with the fans and some clicks as the motor came to rest. I also had the same problem as Jared….one weight was in the 6 o’clock position while the other was at the 7-8 o’clock position. I was advised to tighten the metal retaining clip with a pair of pliers and all should be fine. I tightened the fan clip with the pliers and noticed that the right side was also loose. I tightened both clips achieved a firm grip on both spindles. I ran another load, stopped to change the grit and the tumbler sounded Ike a bucket of bolts for a few second before it froze. It appears that the left side bearing is shot. I wrote back to Lot-O-Tumbler and was advised that replacement motors were out of stock and would not be delivered until mid to late September I checked several vendors and none of them had stock. I don’t believe I did anything wrong or abusive. Looking back at the events, I think the fans were not properly installed hence the bearing problem. My suggestion to Jared and others it to tighten the fans before you burn out the bearings/motor. Here’s the instructions I received. “To tighten up the fan on the shaft ,remove the one the moves and tighten or squeeze the metal clip that holds it on reinstall it re align it and should be good.” I’m out of the 90 day warranty so I don’t know if I’ll get any help from Lot-O-Tumbler. The supply problems are also an issue since the machine will be sidelined until I can find a replacement or substitute. If anyone has some suggestions I’d welcome the help. This machine turned out some beautiful rocks and I’d like to get it running again. My advice to new owners is to check the crimps on the fans since I believe it was an assembly issue.

[@sparband]

Neat. It’s always fun to get new toys. That was clever of you to move the dowel. It really worked. It’s a shame that the factory doesn’t calibrate them properly. I’m sure that they have a lot of unnecessary returns because of that. The towel made a big difference in sound. You could barely hear it with the towel. The rocks polished up beautifully. The rock tumbling award that you won is something to be very proud of.

[@MichiganRocks]

The towel underneath helps a lot, but the machine still makes noise. Don't expect it to be silent. Moving the dowel wasn't my idea, it's right in the instructions that come with it. I don't feel like it's something that should have to be done very often though.

[@juli6497]

Thank you so much! I recently got a lot-o and mine is adjusted just like yours was and I have seen the same speed. I thought I was the problem. Now I have a project today of adjusting my dowel. Thank again.

[@Third_Coast_Unlimit3d]

Thank you for buying a second vibratory! You solved my question and concern of why my rocks didn't match the speed of yours . It's the poor quality control my dowel rod was way off just like your new one . Moved it today and it was like magic fixed ! Thanks again for your knowledge.

[@MichiganRocks]

I didn't buy a second Lot-O just for this video, it was because I had too many rocks piling up waiting for the other one. It was a good excuse to make a video about it though. I'm glad I could help you get yours adjusted.

[@RockandRoadRockhounding]

I bought two of these as part of used lot a while back, that tip about putting epoxy into the dimple at the bottom of the barrel is great, I need to do that. And thank you for showing your process for getting it mounted on the block. I've chewed up rocks by not having mine mounted and know I need to do it, I just wasn't sure what the best way how is. Great content as always, thanks!

[@MichiganRocks]

To put epoxy in the hole in the bottom, I twirled some epoxy on a stick of wood, like you would do with a honey dipper. Then I lowered it in and just let it drip off into the hole. It has never come out in over ten years.

[@angellawson1883]

I cannot thank you enough! Just got a lot o that was running slow, even after I moved the dowel. Then I watched this, and moved it 2cm like u did in video. Perfect!!! Thank u so much

You're welcome. Be careful that you don't move it too far and make the action too vigorous, or you could break the springs.

I just bought the double barrel Lot-o because it was only $10 more than buying the single with an extra barrel. It won’t get shipped for a while and the prices have gone up, but I’m excited! Thank you for such helpful content!

[@MichiganRocks]

For an extra $10, I think that was probably a good move for the extra barrel alone. I'd get enough ceramics to fill the extra barrel and then keep that one for your polish barrel.

Thank you so much for the great video! I am going to try adjusting my wooden dowel tonight on my double barrel since I am not getting as fast of a tumble as others seem to get. Sadly I have had my single barrel for about a year, and the motor needs to be replaced. Sealed bearing are ruined and local repair shop said that it cannot be fixed, but must be replaced instead. I LOVE my lot-0 tumbler! WIth my twin lotto, it 's motor went out (bearings went bad) just 80 days after use, but luckily that one was still within the warranty period and Calway/Belt replaced it very quickly for me! Even with the few issues, I absolutely think these are wonderful tumblers! Thanks for all of the great videos! Tina

[@hbeyer46]

Hans Beyer Watched your video on the Lot-O vibratory tumbler review and enjoyed it. I was pleased with some of the information I didn't know like where the dowel is located on mine. I checked and it was like your example. One item that may be worth mentioning in the Cons section, the fact that the motor is warranted for only 30 days. I have to admit I didn't do my homework so I have only me to blame. I purchased my Lot-O last October (2021) and after less than six months the motor was shot. I noticed the noise getting louder and louder so I checked the shaft on the motor. There was considerable play, I could move one side of the shaft up and down, what seemed more than 1/16th of an inch (just a guess). Needless to say I was disappointed. I have tried to locate a replacement but there seems to be no stock. Hopefully that will change soon. Enough complaining. I really like the tumbler, just bummed for my bad luck. Keep up the good videos. I enjoy them and respect the quality of your shiny rocks.

[@MichiganRocks]

A couple other people have made similar comments about their motors wearing out really quickly. That's definitely a con. Since mine lasted ten years, I was pretty happy. That's my only experience, so that's all I could say.

Thank you! I have run one course of polishing like you demonstrate in this video through a new double barrel Lot-O. It was a struggle because I couldn't get an active enough rotation within the barrel. I paused the video at 18:35 and went to the garage to measure the location of my dowel. It's 3 cm from the inside screw, and one side is even a little more: the dowel isn't parallel with the frame. I'm going to take the measures you did and see if I can get that rolling rotation like you did. Thanks again for making such a helpful video. I really believe the Lot-O tumbler is a superior tool --- once you get it tuned in.

Hi Rob, I bought a Lot-O recently from Rock Shed, but have not set it up yet, as I am still tumbling in stage 1 in a rotary. I didn't read your new description to this video before making the purchase, lol, so I am hoping the newer Lot-O does not have the problems. It's silly that the manufacturer continues to place the dowel in the wrong position for rock rolling action. I also bought a Raytech TV-5 that I read some good reviews on. They sell a kit for rocks that includes a second bowl (good for Polish stage). The Raytech does not require being mounted on a heavy block of concrete, which is a pro in my mind. Eventually, I will be able to evaluate each vibratory tumbler. Lots of patience needed in stage one rotary, lol. Thanks for your videos! They are very helpful. I hope you get the chance to review the mini-sonic from Diamond Pacific. It's kind of expensive but looks to have some decent configuration options. I especially like the idea of being able to adjust the vibration speed.

[@MichiganRocks]

There are some good threads on the Rock Tumbling Hobby forums (forum.rocktumblinghobby.com) on how to replace the motor with a $30 motor that works as well as the original motor. I asked DP to give me a Mini Sonic to review, but they wouldn't answer my email, even when I followed up with a phone call. I would have liked to review that, but I don't really need another tumbler and the price was too high to justify buying one just to do a review of it.

Wow and wow, I have used a Lot o tumbler and am glad to get two years out of a motor! Unfortunately motors are not covered under warranty! My lot o has sounded like a machine gun since new, and indeed the dowel was closer to center between the two reference points, I just “corrected” the dowel position, amazing change to the hum I was always wanting, and yes the rocks and media still rotate about the same, I strongly suspect the wear and tear on the bearings will be different with the smoother operation. FYI I mounted an outlet box on the extended wood plank that was lag bolted to my cinder block with lot o base attached securely to the plank. The 4x outlet box affords two outlets beside a light switch, very convenient. Also a flat 1” piece of board insulation on the bottom of the cinder block makes a quiet installation and does not allow the project to walk. Many many thanks!

I have learned so much from you. Thank you so much. Great video. Thanks for sharing.

[@MichiganRocks]

Wow, you have three Lot-Os (double + single)? That's a lot of space in very fast tumblers. I went the other way and put my money toward a lot of rotary tumblers just to feed one Lot-O. Until about a year ago, one Lot-O was plenty for me. Then again, I'm sort of obsessive about that first stage and getting all the holes out of my rocks so I need more rotary barrels than vibratory barrels.

[@donnalantz7981]

Yes I have both a single and a double. Most of what I bring home is pretty smooth already. But I do have to let some go longer in the first stage still. I don't always have all my tumblers running at the same time either. I'm down by 2 of my rotary tumblers now as well. The 2 I got from harbor freight both died and in less then a year. So disappointing. I'm hoping to build a larger capacity rotary tumbler this year. I finally get the camper here that I'm turning into my workshop, so now I have to fix it up the way I want it to be. I just need the tumblers out of my tiny home to run them. I have tons of rocks just sitting here that I have collected over the years that need tumbled.

[@donnalantz7981]

I think I was not too selective in what I brought home in the past years, so I have a lot of sorting to do now. I know I have rocks I just won't tumble or they won't tumble well so I need to weed them out. I am super selective now days on what I bring home. I need to catch up with what I have first.

Just got my twin barrel Lot-O, used it twice so far following your steps, and one barrel works like your old machine, whilst the other barrel does not. After checking the dowel placement, the good side is 2cm like yours, the side not moving so well is actually more like 3cm. Made the adjustment but have not ran it yet as I only have enough rock to go in the 1 barrel. Waiting on some 46/70 rough stock to get done in my rotary barrels so I can fill my 2nd Lot-O barrel with 220 rocks and see how it works. My machine actually has the rear plate that covers the fan motors and fans, so it doesn't blow anything back up at me. In your video it looks like yours doesn't cover them up, hence why you have to shield your eyes. Guessing they made that improvement at least.

[@MichiganRocks]

I've never actually had it blow anything back at me, but those fans make me nervous. Tumbling grit has to be about the worst thing that you could get in your eyes.

[@mrsluvtolearn]

I am new to tumbling. :) This video was a Godsend for me as they all seem to be! I have an older Lot-O Vibratory tumbler that I bought probably close to 25 years ago at a garage sale. I have never plugged it in until now. Other than a broken spring and a missing cap it seemed like everything is operating fine. I did not realize how the rocks should be moving inside the barrel until I watched this video. Unfortunately the website for this tumbler seems to be out of stock of many things including the spring I needed. I was able to get a cap though. I just happen to have a 3" x 5/8" mending brace that I bought from Menards a few years ago. I wasn't sure if it was going to work because it is more stiff(thicker) than the original spring. The holes lined up perfectly and I installed it anyway just to see if it would work. I also filled the pit at the bottom of the barrel with clear Gorilla glue and replaced the dowel. I started a batch today and "Wallah" it's moving fantastic! I'm still not sure if the glue will help or hinder because the one batch I ran after I filled the pit with glue ended up becoming a big clump at the bottom and I have not had the happen before, even with a broken spring. I'll know in the next day or two if the glue has been a help or hindrance. I ordered two more barrels so that I can have one for each phase. So if I have to remove the glue it will not be a big deal. Thank you for putting together such fantastic helpful videos and congratulations on the first place win of your young student. That's inspiring. :)

[@MichiganRocks]

That information about the spring replacement might come in handy for some other people. I have heard that they're not able to get springs from the spring manufacturer right now. It's nice to know that there's an alternative. I used epoxy to fill in the holes of the original barrel. If your Gorilla Glue doesn't work, give that a try. Doesn't Gorilla Glue expand as it dries? I'd think that could be a problem. Epoxy doesn't do that.

[@mrsluvtolearn]

@@MichiganRocks There is a Gorilla glue that expands. The one that I used did not. I used the clear version and let it dry for a few days. The front of the bottle says 'no foam' and 'water resistant'. So far so good with this batch. I did a couple of spritzes of water this morning. Tomorrow I will remove the rocks and update what the bottom of my barrel looks like. :)

[@MichiganRocks]

@@mrsluvtolearn Oh, ok, I didn't know there was another kind. That type sounds like what you want.

[@mrsluvtolearn]

I updated this this morning but it disappeared for some reason. Here goes again. :) The bottom of my barrel did have a slight clump, not as big as the last one but still there. I popped out the glue just by pushing in the nub on the outside only to find out that there was still a bit of wet glue underneath even after letting it dry for two days initially. Fortunately I have my new barrels already and was able to move to the next stage. If I were to do glue again, I would let it dry much longer than two days or use epoxy as recommended here. I just checked my tumbler after having it ran most of the day and it is moving faster than ever. I'm super pleased. :)

[@GothBoyUK]

Why did someone think it was a good idea to permanently fix an adjustable calibration device (the dowel)? The whole idea of such things is they can be adjusted to accommodate the operating conditions applicable to the final user. Hot glue is fine, perfectly acceptable even, but nailing it down is just bad design. The average, or first time, user is going to have no idea the dowel is supposed to be adjusted because it appears to be permanently fixed. Good job people like you are out there to inform us! 👍

[@MichiganRocks]

I agree, but in the manufacture’s defense, they do mention that the dowel can be moved in the instructions. I don’t know if my first Lot-O has nails or not since I have never had to adjust that one.

[@schramajamma]

curious, does it hurt to add a step of 1000g Al oxide? before the Polish? also, besides wasting grit, does it hurt to use 1tsp instead of a half tsp for the 500, and polish?

[@MichiganRocks]

@@schramajamma Adding a 1000 stage doesn't hurt. I used to run 500 for two days and 1000 for two days. I switched to running 500 for three days and skipping the 1000 and haven't noticed a difference. I don't think using a little more grit should hurt anything, but 1/2 teaspoon works fine, so I haven't tried more.

[@lisazitzmann920]

Hi Rob, we love your videos, and have learned a lot from you! Sure wish I had seen this video before mounting my lot I tumbler, I didn’t paint the concrete block. I did lightly sand it and then cleaned it off with alcohol and we used glue as well as the sticky strips, per the instructions. So far so good. But, despite my intention of only using it for stages 2, on, I went ahead and started a fresh load of rocks in stage one. At first I was so impressed. I literally sat for 20 minutes, watching the rocks go around and within a couple hours, I noticed visible changes and already needed to add a few stones. But now, after several 4-6 hour shifts, I’m not noticing very even wear. Some of the stones have perfectly smooth rounded areas but completely rough uneven spots. Other look barely changed, even some super soft Petoskey stones. Could it be because most of the stones are very small? I mainly started this batch to tumble rough chlorastrolite (greenstones) before cabbing, but I definitely didn’t have enough to fill the barrel. So I added Petoskey stones and then I just started adding everything I felt like. Even agates. The softer stones are doing fine, but the harder ones are barely changing. Maybe it’s not full enough. The instruction said it has to be full. How full is full? Full past the flange? Like should they fill the little half-inch round area that sticks up where you put the lid on? (Speaking of the lid, mine kept flying off, so now I’ve been putting a small square of damp paper towel on the opening before fitting the lid on and it stays on for 12 hours even.) Grit. It said to use half a teaspoon. But as you occasionally add more water, should you also add more grit? I know it’s not recommended to use the vibratory tumbler for stage one, but I thought that was because you didn’t want to contaminate the barrel with the coarsest grit. Now I’m wondering if the action of the vibe just doesn’t do a good job with the rough shaping stage. It would be a shame though, as I am so enjoying being able to check on the stones throughout the process, and being able to take them out to grind out certain flaws that come up, rather than having to let the tumbler remove so much material around the entire stone to even them out.

[@MichiganRocks]

That's a lot to respond to, Lisa, but I definitely have some thoughts and some videos for you to watch. Too many small rocks can be a problem in a rotary tumbler, but I haven't seen them be a problem in a vibratory tumbler. The rocks you're tumbling is definitely a problem. I haven't tumbled chlorastrolite because I don't have much and I'm afraid of grinding too much away. I'd keep it out of the tumbler until you get more experience. I'd then go find one of the Facebook groups dedicated to chlorastrolite and find out what those guys do. Petoskey stones are very difficult to tumble. I would not tumble them with anything else. Here's one way to tumble them: kzbin.info/www/bejne/naO2nY1uaJqJetE I fill my Lot-O right to the top (almost). There's maybe an inch of free space measured down from the very top of the hole. You could do a little less than that, but I typically fill it right up. My lid usually falls off due to a big rock pushing it up. I always loop together about three big rubber bands and use them to hold the lid on. Hook it on the knob on the bottom of the barrel, up over the top and back on the knob from the other side. I use two tablespoons of 220 grit, and then 1/2 teaspoon of 500 aluminum oxide and 1/2 teaspoon of aluminum oxide polish. I never add more grit once a stage has been started. You want the grit to break down over the days it's in there so it might start out at 220 grit but be more like 600 grit by the time that stage is done. When adding water, do it very slowly. You want the rocks to look wet, but not have any standing water in the bottom of the barrel. If it's too wet, the grit will wash of the rocks to the bottom of the barrel where it doesn't do any good. I use a small squirt bottle to add water, I never pour it in unless it's just before doing a clean out. The Lot-O is not good for shaping the rocks. That's why I start my rocks out in the first stage in a rotary tumbler and then move them to the Lot-O later. Here are two videos for you to watch. Watch them, then ask more questions if you still have some.

Hi Rob, Thanks so much for this video. It was a lot of help to me. Just a few days ago I finally got around to setting up my single barrel Lot-O Tumbler. After filling it and turning it on (yeah!) my rocks barely moved. They just kind of vibrated a little, like dancing up and down. So first I thought maybe I had the barrel too full, so I removed some of the rocks and ceramics. Going so far as to actually weighing out two pounds of rocks and 1 pound of ceramics. Still barely any movement to the content of my barrel. No standing water in the barrel was to blame for the inaction either. I remembered your video and rewatched it and writing down the measurements for the location of the dowel. Mine was not in that location so after a short trip to my local hardware store for an 1/4" open end wrench (I think that is the only thing that can remove the 2 bolts underneath the motor bracket) and some 3/8" dowel material the next morning. I went about taking the machine off it's baseboard and repositioning the dowel. Good thing I already have a brad nailer and hot glue gun. Finally my rocks are moving with a nice rotation in my barrel. It even seems to me that the motor is not making as much noise as before and also is not getting as hot.

[@MichiganRocks]

My motor gets plenty hot, so I wouldn't worry about that. I fill my barrel right up to the top, no need to weight anything. I'm glad you've got good action now.

Been running two dual barrel Lot-O tumblers for several years now, the oldest one of the two is starting to see significant reduction in action. I will run two more batches through it and monitor closely. Might need a spring replacement. Will be ordering new springs. Now I do run mine with a less aggressive movement to it due to having it tuned for softer material, and it handles the larger materials just fine. when I get the springs, this will give me an opportunity to test this further. The motor issue that has been running around about these tumblers is disappointing. Hopefully the motor issues will be worked out. Also if you fill the barrel with water for your cleaning cycle, it will be easier to clean them and it will work polish out of any cracks that could be in the stones. And Dawn Dish Soap (the blue stuff) works the best as well, and I have tried many.

[@MichiganRocks]

I always add some extra water and a squirt of dish detergent about 15 minutes before cleaning out the barrel. I use Palmolive because I can get a bottle for $1.25 at the Buck and a Quarter Store. I haven't experimented with other brands, but that always does the trick for me. I have been running a single barrel Lot-O for about 12 or 13 years. I have never replaced the springs. When my motor when bad, it developed a buzzing sound that lasted several years before it actually died. Next time I replace a motor on either of mine, I'll be using a $30 motor that has been a popular replacement, although, it requires either making a part to install it or cutting part of the frame. Here's one way to do it, but there are other ways too. Just search the Rock Tumbling Hobby forums. forum.rocktumblinghobby.com/thread/101420/lot-motor-concrete-video

I ordered a Vevor 3Kg tumbler, received it yesterday. I purchased it so I could grind red porous lava rock to its finest sand/dust state to use for fertilizer. I used it once, about a decade ago, and the tomatoes I grew that year were like no other. I am repeating the process, but, instead of obtaining the pulverized lava rock through beating with a hammer, I am using the Vevor tumbler. I found that the mutt rocks I put in with them have had markable improvements in their surface (smoother, far faster than just with any grit I had used before) with less than 18 hours of tumbling. Have you ever tried the garden/house border/grill bed red lava rock as a surfacing device, before? (I am not using grit, just the lava rocks, which should make the silt accumulated completely garden-friendly)

I don't think that tumbler is made for rocks, is it? I just looked at it and it doesn't say anything about tumbling rocks with it, only jewelry. I'd hate for you to ruin it on your first use.

Thanks for all the info. If I make a relief in a rock pendant or etch lines into rock using a rotary tool, will the lines and small areas I cut away polish out if I put it through the stages of the rock tumbler? The grit will be enough to polish those crevices?

[@MichiganRocks]

I doubt it. It's not just the grit that needs to get in there. You need something to rub the grit into those areas. Even rocks with larger concave areas don't tend to polish very well in the concave parts. I once broke up bottles and tumbled the glass. The outsides of the bottles got nice and shiny, but the concave curve on the inside didn't get nearly as shiny.

[@TimberwayDesigns]

Just the info I was looking for, I am getting good results but my rocks never moved like yours did (your old model) I thought maybe the older models were better designed. Another thing to be aware of is the bearings will come loose on the motor, mine lasted about 2 years. The motors are replaceable but be prepared for the price.

[@MichiganRocks]

My first motor lasted ten years or so, but you’re right about the price of a new motor. Ouch.

[@doubledragon9530]

What I've found with this tumbler is that if you don't fill it up enough with rock and especially with ceramic tumbling media, it just won't roll like it's supposed to. So if it looks like yours is just really weakly tumbling, or just sitting and jiggling, check how much stuff you have in there. Ideally you should have about half rocks and half tumbling media, and together they should be nearly to the top, no more than an inch below the top rim. Also, don't try to tumble too many large rocks at the same time. A mix of medium, small, and a couple or three larger rocks works well.

[@MichiganRocks]

That's right, it does need to be filled up pretty well. I sometimes run it with more than an inch of empty space and it does fine, but I'd rather utilize all the space inside if I can. I don't think you need to have 50% ceramics, but it doesn't hurt to. I'd say for me about 30% is the minimum amount. If I'm tumbling lots of flat things, like Christmas ornaments I make, or cabochons, then I bump the ceramics up to 50% or more.

[@rkipperkelley3152]

Thank you again for your videos, bought a Lot O for polishing. Following your advice to the T but polish & borax becomes stuck in bottom of barrel no matter what I do. At first I put all the borax and .5 tsp polish in all at first to avoid the fans, thought it was the reason. Dumped that out and again made sure water was drained as you did, upside down. This time I added the 1Tbl of borax slowly as it was turned on, then added the polish slowly. Nothing... just dry looking rocks tumbling around again with nothing sticking to them, no white slurry at all. I waited a while to make sure it didn't need to mix, nothing... Dumped rocks out second time to find everything stuck in bottom where that indention area is located. Do you have any suggestions? Too wet? Too Dry? Surely I don't need a scientist every time I mix? I used about 1lb ceramic to mix bringing it to an inch from top or so, movement is good. Thanks.

[@MichiganRocks]

If the movement is good, then there must be something wrong with the amount of water. You should fill it with water right up to the top. Then drain out as much water as you can. Tip it over and let it all drain out. You don't have to let it drain forever, just until the majority of the water is out and then leave it upside down for another ten seconds or so. How long are you waiting before you give up on it? It takes awhile for the slurry to develop. I'd leave it alone at least over night if not 24 hours. By then you should definitely have a slurry developing. Remember, polish is a very, very fine grit, so it's not going to remove hardly any rock like the other stages did. That's why it will take awhile for a slurry to develop.

Maybe twice the speed of your video. Anxious to see the results. Thanks again for the great info. Gene

[@MichiganRocks]

I have heard that if you move the dowel too far that it can break springs. I think you have already seen that by shearing a bolt. You should probably tune it while it's running to get the action to be about like how my original machine runs. I wouldn't want it running twice as fast.

[@danwellbaum4026]

Thanks Rob, I moved my dowels too. Made a big difference. Also I was wondering if a cab machine is better than a flat lap or how do choose which one to use? Thanks again

[@MichiganRocks]

I think a cab machine is way better that a flat lap. With a flat lap, it's hard to see what you're doing. You're looking at the back of the rock or cab. With a cab machine, you can look down between the cab and the wheel and see exactly where you're at. The other thing I like better about a cab machine is it seems to work a lot faster than a flat lap. I have diamond wheels/laps for both machines, but a flat lap just doesn't work very fast. The downside to cab machines is the cost. Both the wheels and the machine itself are much more expensive. Check out my review of the Kingsley North cabber if you missed it: kzbin.info/www/bejne/pGSTknWKqp6Cobs

[@danwellbaum4026]

Thanks Rob, I have a cab king and was thinking about getting a flat lap. I might hold off for a while until I have a real need for one. May be face polishing a nice flat surface.

[@MichiganRocks]

@@danwellbaum4026 Flat laps aren't as good at that as you might think. At least I have a really hard time doing that. I tend to tip the rock a bit and get the edges more than the middle. Even small flat rocks take a much longer time to polish than a similar size domed rock. You might want to look into a vibrating flat lap for polishing a whole slab or half a rock. There is a learning curve with them, but I think that's a better tool for the job.

Thanks! Looking to get one soon. Question… Rockshed sells rotary grit and vibratory grit. What’s the difference? And can you use stage 2-4 grit/polish interchangeably? I’ll stick to the rotary for stage 1. Thanks again 😊

[@MichiganRocks]

I don't think there's a difference other than the rotary pack included a coarse grit. Really coarse grit isn't usually used a vibratory tumbler. I do what you are thinking about doing. I do the first stage in the rotary and the other stages in the vibratory. Those last three grits could be used in either type of tumbler.

This is probably the best video on which to post my major question: I have a 1year old Lot-O that I've been using continuously since I received it. I had to tune it by moving the dowels as you show here and I have good movement. I consistently have problems with the first Lot-O stage. It starts slowing down within a few hours, and I check it often adding water to keep it moving briskly. Invariably however, I end up with little or no movement with all the ceramics in a glob on the bottom, often difficult to remove-sort of a paste embedded with ceramics. Am I adding too much water? I even tried doing this stage with borax added but it doesn't seem to help. Any ideas you might have would be highly appreciated. As an aside, I have not seen anyone who has done more for this hobby than you. There is nothing like learning from and expert who happens to be a gifted teacher as well! Thanks for all you share! One other question-I am enamored with BIF and banded chert. I recently found a ton of BIF in Wakefield, cut it up (tile saw) and am tumbling it now. My question is can you direct me to any beach that contains banded chert because here in SW Michigan I can find it. Thanks again!

[@MichiganRocks]

Hey Rick, based on the glob of rocks in the bottom of the barrel, I'd say you're not using enough water. Don't add borax in the first stage, it thickens the slurry and just adds to the problem. I occasionally forget to check my Lot-O in the first stage and end up with the exact problem you're describing. You should start with just wet rocks. Give them a few extra squirts of water before you go to bed to get them through the night. When you wake up, check them again. Squirt in enough water to keep them looking wet. I check them two or three times per day. As long as they never get too dry, I don't think you'll have the globbing problem. I find almost all of my banded chert on a beach that has no public access. I find a little of it up on Lake Superior, but it's never as good as the stuff I find in Lake Huron.

Thanks Rob! I’ll use more water.

@@MichiganRocks I’m very appreciative of it I really enjoy it and your videos

[@followingmypath3144]

Thank you for such detailed videos, this one and the one with comparison of two tumblers. I needed this instructions desperately when I bought my first Loto tumbler few months ago and was looking for a good instructions. I ran few batches on it already and was able to get decent polish, but I also noticed how rocks moved slower than what I saw in videos of others. Now I know why - thanks to you. That dowel on my Loto is also in the middle and now I know how to fix it!. But one my question still remains - why the one cannot use loto for the coarse stage? Just run it longer, three-four days maybe? I do have rotary tumbler for that but was just curious why this not even explained anywhere :)

[@theduderollsrocks1843]

Look at the other video, "Rotary vs. Vibratory" at 3 : 15 where Rob shows rocks he tried to shape in a vibratory for 28 days.

[@MichiganRocks]

I have never tried a more coarse grit in the Lot-O. I have heard that more coarse grits are too heavy and just fall to the bottom of the barrel. This doesn't grind the rocks and also wears out the bottom of the barrel faster than usual.

[@powerlinekid4296]

Good review. Just a couple of additions, FOLLOW MICHIGAN ROCKS directions, not the confusing ones that come with the tumbler. Those instructions, say "adjusting the dowel is not recommended until you are familiar with the machine", which if isn't working from the factory, you'll never be able to become familiar with it. The buyer will just have buyers remorse. My Lot-O didn't move rocks either, until I readjusted the dowel. Ten minutes after I plugged it in for the first time. You also need to make sure the weights are in same place, which is another quality issue. If the weights are even slightly off they can cause very bad shaking, and no rolling action. The rubber band holding the lid is best way to keep lid on, don't poke a hole in the lid as instructions say. The lid will still come off and the slurry turns into sludge while you're asleep.

[@MichiganRocks]

I poked holes in the first tow barrels I had, but not the new ones. The lids aren't so airtight that they're going to come off due to any gas pressure build up. They're much more likely to come off because of a rock pushing them up. I don't think the directions say to never move the dowel. I would be careful to know what you're doing before moving it though. Good point on the weights, although I didn't check them that closely. I'll probably check them now that you mentioned it though.

[@powerlinekid4296]

@@MichiganRocks Thanks Rob, I dug up the Lot-O's instructions and edited my comments. You are correct. In addition, I have had to adjust dowel (other times) for different sized rocks to get the correct roll.

[@MichiganRocks]

@@powerlinekid4296 On my first machine, I have never adjusted anything. It just works.

[@jerryholzinger1532]

First off thank you so much for the videos it's opened a new world for me. My question is, if you're not recommending the lot o tumblers anymore, what are you recommending now? There are many other types of vibratory tumblers out there but I have no idea which to look at. Thanks again for all the insight on My new hobby!

[@MichiganRocks]

If it was me, I'd still buy a Lot-O, but I have trouble recommending that other people do the same. I did hear a few months ago from someone who should know that the motor problem may be better now than it was. I can't make any guarantees but hopefully, they're using something a little more reliable now. I don't know what else to recommend. I asked Diamond Pacific to send me a Mini Sonic to review, but they didn't answer my email. I have one friend who says it works great, but takes about twice as long and another friend to who said that it would just make me appreciate how good my Lot-O is. Since they wouldn't send me one, I can't give you my own opinion. I'd also take a look at the Thumler's UV series.

[@jerryholzinger1532]

Thanks for the quick reply! I'm going to go ahead and stick to looking for a Lot-o once they become available again at Rock shed or Kingsley. Everybody seems to be out of stock.

@@MichiganRocksThe DP vibes are terrific. Super-thick barrels, and you control the speed with a dial.

[@KaneLouiseOconnor]

this is great info. thank you. now if only they would make a barrel with a larger opening to accept upto 5 inch slabbed and shaped pieces.

[@MichiganRocks]

There are other vibratory tumblers. The Thumbler's Ultra Vibes come in several sizes and have much larger openings. I have never used one, but they have a good reputation.

[@KaneLouiseOconnor]

@@MichiganRocks I will be looking into them. My husband has a vibratory tumbler for his brass shell casings, but I really don't want to end up with another of those style.😅

[@MichiganRocks]

@@KaneLouiseOconnor The tumblers for brass are not built for the weight of rocks and the barrels aren't as strong either. Better not to use his anyhow.

[@deantronnes6730]

I added a cement vibrating unit to mine after the motor died. I bolted it to the top and it is adjustable for how much it vibrates. Much better bearings and cheaper that the original.

[@MichiganRocks]

Did you get that idea from Chuck (Drummond Island Rocks) on the Rock Tumbling Hobby forums? It wasn't his idea, but he did a nice job of showing his process. forum.rocktumblinghobby.com/thread/101470/finished-batch-watt-concrete-motor forum.rocktumblinghobby.com/thread/101420/lot-motor-concrete-video

@Michigan Rocks I don't know. I like to think I thought of it but I'm old.

Maybe you did. I've just seen other people discussing doing the same thing.

[@jamesfowley4114]

Walnut shells make a nice finish too. I used that to polish brass.

[@MichiganRocks]

I know people use walnut shells, but I have not used them myself. I have only used corn cob for dry tumbling.
