Homemade 2" x 72" belt grinder and 9" disc sander combo

[@tealgunner]

Dan, that makes perfect sense. Awesome idea. I can see how the nature of it being a whatever spring makes it totally adjustable over time or just for your taste. I must say that your ability to design and build based upon common sense, simplicity, and efficiency are impressive. Thanks for replying.

[@51barnfind]

Nice job !! Thanks to you now I have to change my design because I really like that disk grinder you added. LOL It makes a better unit for sure. Back to the drawing board.LOL Thanks again for sharing!!

[@paulcastro1361]

So simple yet so nice. Thanks for sharing!! Nice bike too!!

[@antonsmutny4608]

Great job! I tried to find a belt grinder design which should be easy enough to do it at home with my common tools. Your design is the best one!!! Thank you for inspiration

[@bobainsworth]

Very nice design, best I've found so far....great job!

[@ShannonLacey78]

this gave me so many ideas with my upcoming grinder build... good job dude.

[@matejsmetka2968]

Great job, i love your design the most! I Love the combo idea! Its very variable. This is exactly what i was looking for on youtube.

[@danfuller8265]

+Matěj Smetka Glad the video helped you, good luck!

[@Jace_Roams]

thank you! I have been looking all over for a good set up. this thing looks great!

[@buck73ra]

Sweet! This is exactly the configuration I m looking to make. To reverse the rotation of the motor just switch the negative and positive in your switch.

[@crappiejosh]

man that's probably the sweetest design I've ever seen in just started a 2x72 belt sander today but I'm thinking about scraping it and using a design like yours because that's the slickest design I've seen so far and I've been looking and doing research for almost 8 months so far

[@danfuller8265]

+crappiejosh Wow, that's quite the compliment thank you. Hope your build turns out great.

[@seaforb13]

Nice work. Very efficient strong design best home made I've seen. I'm going to have a crack at making one thank you for sharing.

[@LarryM5291]

I like your design, very nice. One thing you can do to reduce slop in the tubes is put your set screws (eyebolts) in the corner of the tube. That way you are pushing the inner tube into the opposite corner. Which will eliminate the slop.

[@evoche]

One of the best belt grinders I seen on you tube!

[@advancednutritioninc908]

Excellent Workmanship!! Great Idea too!

[@Dobemandan]

Fantastic! Well done! Love that VMax as well! :-)

[@danfuller8265]

Thanks! I bought my belt at a wood shop store for $20. They are called "Grizzly power twist v-belts". Amazon has them but they are expensive. My RPM's are 1380, 2588, 4600, 8625 Google "pulley speed calculator" and you can figure out your speeds based on your motor rpm. Great idea for fixing the vertical post. I used a previous suggestion though. A foot pedal would be nice. My setup would require it to be rated for a 2hp motor, 240 volt 15 amp motor. Not sure I want to dish out the money.

[@danfuller8265]

Finally got around to taking your advice. Worked great thank you.

[@MrMixosnow]

Awesome job great ideas combination 👏👏👏👊👊👊

[@johnranalletta9249]

Nice job. I'm going to follow your example. About the sliding tubes, you probably already know this, but the larger tube has an internal weld seam. If you grind a shallow slot on the smaller tube and just flap disc the corners, it will be much tighter and slide easily. Best.

[@nickabbott8453]

Nice job Dan. I am getting close to building my own belt grinder. Yours looks professorial. I hope mine turns out as nice. Thanks for posting the video.

[@danfuller8265]

Thank you. That's the best idea I've heard yet. I already took someone else's advice but thanks.

[@jakysz145]

This the best homemade belt grinder that I have seen

[@danfuller8265]

A lot more then expected like all projects I seem to do. I'd say around $450. The step pulleys and idlers really set me back.

[@michaelflynn6178]

great build thanks for sharing

[@danfuller8265]

Close, there is a spring under the arm. The square tube that holds the pulley is capped off on the bottom. Just throw a loose spring inside the other square tube (the piece that is welded to the frame) and your done. Hope that makes sense.

[@charruauno386]

Sorry I forgot to mention very nice job, I was very happy to find you.

[@Smalls4068]

great build. looks well thought out.

[@danfuller8265]

That's funny, I know the feeling. I redesigned mine several times.

[@danfuller8265]

Thanks. I love the bike too.

[@guillaumedupuis777]

Nice job buddy.

[@knifegunguy]

I've watched a lot of videos and I like your design the best I think I will build something very similar. Thanks

[@danfuller8265]

+knifegunguy Right on thanks, have fun.

[@balisticsquirel]

Thank you for sharing.

[@BigIronTV]

cools sander build. very nice Vmax.

[@BrokenRRT]

Outstanding ingenuity and fabrication! I enjoyed this video and it inspired me. 2 questions: where did you buy the drive belt ? Do you know roughly what RPM difference is between the 3 belt speed Pulleys are? As far as you grinding the vertical post too and it now has play...you can just weld a few beads or dots down the sides of the square tube then file down to tight fit.. They will take up the play. The switch I would change to a foot switch.. find one on amazon as low as $9.00.Thanks !

[@danfuller8265]

Yes both the contact wheel and idler rotate together. Not sure which belt you're talking about so I'll explain both. The motor is on a hinge that allows the weight of the motor to pull tension on the belt. So far I've had no issues with it. As for the sanding belt, tension is adjusted using the idler arm. Underneath the idler arm is a spring I bought from Ace hardware that pushes up on the idler arm thus putting tension on the belt. Sorry, I should have shown that in the video.

[@stizan24]

I'm gathering the materials right now lol. My motor shipped yesterday and I got.my spring 3 days ago. now I need the steel, wheels, pulleys, blocks, belts, and hardware. I also need to run 220v 20amp to.my garage but I need to install a sub panel to do that. fun fun fun. I will be up and running by 4th of july.

[@danfuller8265]

+stizan24 Nice, sounds like your on your way. Lately I've been using a 3000 watt step up transformer so I can run it off of 120v. I've only got one 220v plug in the garage and I need it for other things.

[@stizan24]

+Dan Fuller when my motor came it was wired for 120 so I wired on a power cord and plugged it in and it runs fine. I will see how it runs under load. I don't want to have to do a sub panel if I don't have to. my electrical buddy says I could swap my 15 amp for a 20 if I need to. as long as the motor running isn't pulling more than 18 amps I should be ok.

[@danfuller8265]

Come to think of it I'm running a 20 amp breaker on that 120v line. I haven't tried it on a 15 amp breaker. Hope it works for you.

[@stizan24]

+Dan Fuller it should if the run isn't long. it's about the guage of the wires in your wall. if they are 14 guage they could fry if the distance or.load is too great. if they are 12 guage you are gravy.

[@RJB_FixinStuff]

For future builds the motor rotation can be reversed by usually switching two wires in the j box. If the label is missing it my take some research online but it is usually swapping two wires between pairs.

[@duramaxmak]

Nice job do you have link to company you purchased your wheels from?

[@danfuller8265]

Yeah you could go crazy with upgrades, but I spent too much money as it is. I agree the switch could be located better. I like BrokenRRT's suggestion of a foot pedal.

[@Alamodem]

Nice design.

[@Harleymansgarage]

Awesome work

[@danfuller8265]

Thank you sir

[@tealgunner]

So, the vertical arm in the center--with the pulley used to adjust tracking has a spring inside the arm? That is a tremendous idea.

[@GoGreenMan]

where did you get your disk for the disk sander?

[@danfuller8265]

Good to hear, that was the intent. Be sure to post yours when it's done. We all need ideas.

[@tealgunner]

Sorry about the type. Question. It appears that the contact wheel and idler pulley are fixed together so they rotate together. Is that right? Also, how do you keep tension on the belt? Thanks.

[@mortamersnerd6264]

To change the rotation, I'm sure you just pull the back cover (2 screws) and swap the wires there. I'm lucky mine has the shaft coming out both ends. It seems a bit loud. Are they all like that or is it the recording making it sound like more than it is?

[@danfuller8265]

Maybe you're right. Yeah it makes some sound. There are a lot of bearings moving and friction with the belts but the decibels are well below the need of hearing protection. I can't speak to other grinders I've only heard my own.

[@george330ful]

Good job be proud I like seeing different ideas if it works it is not wrong it it is your way

[@danfuller8265]

Thank you, it's nothing special but it works well.

[@rotironwerks]

Your vertical tracking arm could be shimmed by running a weld bead where needed and grind down to fit. Nice job. Best design !

[@parrishparrish3084]

Nice Vmax ...

[@bobbyabbott3035]

I don't know dude looks pretty good to me for a home built sander. I'd use it

[@LastManAliveProject]

good job.

[@19jamesbradshaw92]

Awesome, iv been researching to make my own. how much $ would you say you put into making this beauty?

[@danfuller8265]

Around $450 dollars. I'm sure there are much cheaper ways of doing it. I went all out with my Idler's and step pulley's.

[@19jamesbradshaw92]

I see, lol i already just bought a cheap 4x36 . Thanks tho when i upgrage im gona make one.

[@danfuller8265]

Haha nice, sorry it took three months to reply. Hope my delay wasn't' a factor for buying the 4x36. Take care.

[@rinaldofaria]

Dan, do you have (provide) any plans about this sander?

[@danfuller8265]

+Rinaldo Faria Sorry brother no plans.

[@rinaldofaria354]

+Dan Fuller Ok. Thanks anyway.

[@heettreet]

for the most part i like your fabrication ,, of course you could spend mucho bucks for upgrades ,,but this is great ,, the one thing i would say is , the off switch is not very handy i don't think , in and emer , i would not want the switch that far back ,, i'm not there and haven't used your rig so maybe i don't see something ,, nice info

[@ATOMKILLER100]

good job

[@tealgunner]

I'm an aspiring knife maker and looking for ideas. This is a superb statiom.

[@Manuel_Z_Kayaks]

You should use a tension arm like the one in a car for the snake belts

[@danfuller8265]

That would be cool, I think I've seen a video of somebody doing just that.

[@superman4ever0311]

How much did the materials for this cost

[@douglasalan7786]

That's a real nice build. Clean and to the point.That rotating platen will come in handy if you ever start working with tube and pipe. You can get several contact wheels from 3/4 up for fish mouth fitting if you need to.Just get Sunray to make them. The knife tool guys are a ripoff on wheels.Don't use Sunrays web form. Just pick up the phone call Devin. He knows his shit.

[@danfuller8265]

+Douglas Alan Thanks for the info I'll look into Sunray.

[@xs65081]

Nice.

[@Stoney327]

Dan For whatever it's worth, your belt is called a Vibration Free Link Belt. They're available through Harbor Freight at www.harborfreight.com/vibration-free-link-belt-free Just in case anyone is interested. I used a ton of those things when I was a mechanical engineer. Very forgiving. Take care. Dave Pappy Dave's Knives

[@simonbrown3943]

Like the design..... why dont you try a drinks can shim for the tracking arm to tighten it up

[@fasousa4798]

Best thinkg is the Gen 2 in the background

[@corgill1]

What size drive shaft did you use?

[@danfuller8265]

+Matt Corgill Hey Matt, it's running a 5/8" shaft.

[@corgill1]

+Dan Fuller thank you so much for posting! Your design is exactly what I was looking for!

[@96tp]

To get the motor turning everything the other way couldnt you of just turned it around?!

[@boromirrus2562]

Hi Dan! Share drawings!

[@danfuller8265]

Thank you sir.

[@TheFreeWayGearReview]

Forget the grinder! Let me get that Vmax!

[@BelnapCustomKnives]

pretty cool

[@richard2mitchell]

where do you live?

[@geedubb2005]

hey Dan, how bout an update please

[@gouuful]

mmm V-Max ;)
