Dominic, this looks like an interesting project! If the large disc ends up turning too fast, you may need to bolt/screw a smaller disc onto its side and use a second belt to drive a 2nd large disc which could hold your yet-to-be-received lapping discs. That would allow you to get a much slower RPM for lapping/grinding your scraping inserts. The "slow" grinders that I've seen for things like sharpening wood chisels turn much slower than your existing large disc. If your belt slips too much on the motor's shaft, you'll probably need to increase the OD of the "pulley" that you are using right now. Also, if you are willing to show your viewers what tools, tooling, materials, etc., that you have, one or more of us may be able to recommend a way to use what you've already got to make a tool, do something easier, etc.
If you put a "crown" on the belt mating surface of the pulleys, it will probably track better. Assuming the "pulleys" are aligned. I agree with bovines00 that a two belt system would get you the speed reduction you are looking for. I am am looking forward to the finished product. I like home made fixtures like the one you are making. KOKO!
@@etbuilds6006 hey, on the video it does seem to go fast, but it's not that bad. and that disc still needs to be straightened out a bit, it wobbles a little bit.

@@bobvines00 hey bob, thanks for your tips. and yes, maybe I could have shown some more materials. will try to remember👍🏻

That's right, I should have done that. and there will be another part when I have time. and worked it out in CAD so that I won't be surprised again.
Looks like you have a good working idea. 👍
@@hilltopmachineworks2131 thanks Tom. Hope so 🤣
Nice work, making something from nothing! It may be turning a little fast, but if the disk is running true, I think it will work ok. Cheers!
