I love that you took your discs to the microscope, killer mission. You're illuminating what these are actually made of and do which is a service. It's useful for folks to see this so they take good care of their discs (I've seen some abysmal practices with cross contamination and the like). Dust, because it typically contains quartz, is ranked a 7 on the mohs scale. Even leaving your higher mesh discs out in the open can lead to scratching contamination. It was awesome to see the blue under the microscope with the little inclusion. I'm going to have to check mine out, I agree the value is definitely there, they last a long time. Thanks for an awesome video, really enjoyed this one.

[@CurrentlyRockhounding]

I have been thinking of my storage of these as well which like you brought up can be an issue in a shop with the dust. I'm going to try and find some kind of Tupperware I think to store them in.

[@OzoneFineArtVentures]

@@CurrentlyRockhounding I have ziplock freezer bags with their corresponding grit/color (again to not contaminate) to keep them clean and then I always wash them before I mount them on the machine just in case. All you need is to drag a scratch through a great polish to get really uptight about your storage solutions! I also have a separate, large, bristle brush that is labeled for each disc. That helps with the cleaning.

[@brushbros]

@@CurrentlyRockhounding That is a good idea for polishing grits, but not necessary probably for coarser grits. I have used the same idea, it works very well.

Thanks for this! I bought the hi-tech slant lap about 5 months ago and it’s hard to tell when the discs are getting worn out. This video is helpful :)

[@CurrentlyRockhounding]

I think they are worn out when the black plastic disc can be seen.

[@sandmaker]

I agree, the more water the better. Too much pressure will snap the diamonds out of resin, let the lap do the work. I have laps that are 10 years old and some new. Loved the photomicrographs. Keep the goodness coming. Be happy, safe and stay healthy😷⚒

[@brushbros]

Wonderful and informative video. The microscope tells the story (thanks to you.) To clean both metal and resin disks (and wheels) I use sink cleanser and a stiff brush under warm water. Use a lota lota water to avoid "mud" collecting in your drain. Both types are "dressed" because the softer "substrate" is abraded while the proud diamond is unfazed.

[@paigelee6321]

Very informative, interesting,thank you for sharing 😊💙

I'm glad you liked it, I thought it was kinda neat to see the discs like this.

[@ambkbero2]

I bought my 8" slant lap because of the first review you did and I was not disappointed (yes, I used your code). Although I must say that I prefer the diamond disks over the resin pads. I've reserved the pads for basic pre-polishing and a separate felt disk with cerium oxide for the final polish. thank you for the great adventures and product reviews, You ROCK!! (I know that was cheesy but I couldn't resist)

[@CurrentlyRockhounding]

What grit of diamond discs do you have? I have been thinking about buying some higher grits to test out.

[@ambkbero2]

@@CurrentlyRockhounding I getting all of them from 60# to 3,000# the resin disks w/pads seem to be more for polishing and the pad helps on softer material. But when it comes moving material quickly the diamond laps are my choice. I do most of my work in the winter so I'm planning to buy the whole diamond range of diamond plates soon.

[@SilicateSyndicate]

I'm alittle late to the party here, but this video is awesome. I just bought an 8" a couple weeks ago and am loving it. I have a good saw and a cab machine also, so its been nonstop lapidary even more so lately. Love the channel! High Fives from southwest Utah

[@CurrentlyRockhounding]

Thank you! I'm glad you like the channel. I think the hi-tech lap is a good machine but the water cups are pretty meh but that's an easy upgrade, have you changed yours out?

[@johnhodgson4216]

I use CLR to remove the deposits by tap water, which fills up around the diamond, so when I give it the CLR soak, the lap is very clean and sharp.

Nerding out is waaaaay cool! Attention to detail is important, and you do that. I had wanted a microscope for my horticulture studies, still do not have one, but your video showed me what I mihght want to know about the discs! Thank you, you are doing a mitzvah-a good deed!I am still in the process of setting up a proper system, and it is a challenge. I picked up a dial gauge on a magnetic base-for determining the true of my machines and discs, I guess-I bought an inexpensive faceting machine and wanted to be sure the grinding wheel sat just so on the hub before I tried to facet any gemstones. Also I bought some low quality rough TO PRACTICE ON111 Very economical!!!! Just thought I would pass on an idea or two-the only thing holding us back is our imaginations-YOU GOTTA USE IT! ha ha!!

Thanks for this video. As a raw beginner this has helped me identify one of the pieces of equipment that was left to me. Sure, I could have looked in a book or catalog, but I hadn't gotten around to it yet. Now I know what I have AND I know more about the disks. Microscopes are super handy. I've put off buying one and have one in one of my amazon wishlists that I've been thinking about for my saltwater aquariums and my koi pond. I'll go compare the one you have to the one I've been thinking about, the more versatile one is for me, the better. I have way too many "hobbies" that need to have one. I hate having to wait until I get to work to sneak look at something under the 'scope. LOL

[@hockeyrace]

I love that you used the microscope to check these out. I was just googling to find out why I feel like I blow through these discs. I found this video and I’m super surprised I missed watching this one 😳 I bought another set thinking they were done. I’m now thinking they probably are not. I still feel like I’m dong something wrong because I can’t seem to get a really good end result. I clean each of them with soap and water and brush them with a soft toothbrush. I spend ALOT of time making sure I get all the scratches out and look all the time with a jewelers loupe. I can’t afford to keep buying so I do everything I can possibly do to extend the life. As for contamination, I absolutely do have a disc that I believe is ripped. I don’t have a microscope, so I’m not 100% sure. But results are certainly telling. It happened with a rhyolite/agate. . Anywho, I’m happy to have found your video while googling. 👍. Thanks for sharing. Stay Crystal 💫 Maribeth

[@CurrentlyRockhounding]

What are the grit stages that you have been using? You should be able to get a really nice finish on your rocks.

[@hockeyrace]

@@CurrentlyRockhounding diamonds discs- 80, 150, 180. HI-Tech resin discs- 220, 325, 600, 1200, 3000. I’ve worked through all kinds of troubleshooting too. Speed, Water, Time, Drying to Look for scratches, Loupe. I get good results on about 20-25 cabs. After that, everything is garbage. I use a lot of grits to get a good finish. They just don’t seem to last for me. I’m not a brute! I’m an intelligent person who can usually troubleshoot anything. I’m stumped with the hi-tech flat lap discs. 🤷‍♀️

[@CurrentlyRockhounding]

@@hockeyrace From the sounds of it you're doing everything correct. Maybe we could continue this conversation over email and then we could also share some photos on the subject.

Great video. Didn't expect to get the up close and personal. I need to find someone who uses a flat and get an in person demo. I'm pretty invested in wheels.

Thanks, those discs were in much better shape. Increased water and washing the discs when your done. If you take good care of your equipment, it will take good care of you.

[@CarlDi3trich]

Forgot to ask....do the pads with acrylic backing have some give? Do you really need the "spongy" backing Diamond sells?

[@CurrentlyRockhounding]

They really don't have much give to them at all. If you want to make cabs then sponge backed wheels or pads is important.

@@CacklingChick I guess I should have been more clear about that, sorry. I think the flat one has more options cause you can stand at it, sit at on a stool and if need be you can tilt it some. How do you plan on using it and what do you plan on doing with it?

Great video and great channel, I've been learning so much! I was curious if you have ever stuck these PSA resin discs to BOTH sides of the black acrylic disc to economize and conserve space.

I’m to the point of wondering how my disks are wearing. This is a great way to show how they work and wear, but I wish you would have mentioned what to do if we do have buildup or need to expose more diamonds on the 80/180 grits. I use the hell out of my 80 grit and have heard dressing it will help, but I have no idea what grit to use. Can’t really find 80 grit sticks. Can I use the 180 or the 220?

[@CurrentlyRockhounding]

Things like dressing sticks really do nothing at all. You can clean discs out with dish soap and hot water but once the diamonds on the electroplated disc are gone there's not much you can do since its such a thin layer.

[@anitawilliams2187]

Can you wash/scrub the polishing resin discs like you can the Diamond get grinding discs?

[@CurrentlyRockhounding]

Yup! I just use warm water and dish soap. I don't scrub it really with anything, other than rubbing the soap in with my fingers.

[@iainwhitford7602]

How does this compare to the Richardson dry polisher?

[@CurrentlyRockhounding]

Two different worlds really. The Richardson High Speed Sander is really good for big rocks that can really take some heat but other than that it really starts to lose to the wet flat lap. You can make a cab on this as an example vs. the Richardsons.

[@christopherort2889]

I agree. I use lots of water and my pads last forever.

[@mattcorbitt252]

You said you started using a lot more water.. how did you do that?

[@CurrentlyRockhounding]

You can control the amount of water you use, just turn it up.

[@mwilson14]

You know that I pan the synthetic diamonds out from my wet tile saw water right? LOL. I have a collection of them, but they are more of a byproduct from me panning my tile saw water to find anything at all that is heavy, like gold and zircons as well. I just can't pass up the diamond collecting and I also pick them out of my rinse cups for my masonry files. You should also hit those synthetic diamonds up with UV light. They typically glow bright blue, which is fun.

[@CurrentlyRockhounding]

So you're saving the slurry from your saw then or are you doing it after each use?

[@mwilson14]

@@CurrentlyRockhounding I sometimes pan it after one use depending on what I've cut, and this is usually a mix of different rocks I cut for a single cutting session.--typically rocks rich in sulfides and other minerals which are worth my time to process for element extractions. I have old milk jugs stored away with the drained slurry from many sessions that typically are more silica rich. It settles out over time and the water is decanted into another container so I can filter it and safely poor it down the drain or water the plants out front. I'll save the dried powder in containers for chemistry experiments or for use in homemade refractory ceramics.

[@mwilson14]

...so in other words, I don't pan every single batch of rock slurry to get the diamonds. It's fun to find them if I've got a day where I don't really feel like studying and need a break from searching for other things.
