Thread: DMT Duosharp as lapping plate

+100! I have the same model, and it's the best lapping plate I've ever used. The size, thickness, holes, and dual grits all add up. After the 220 and 325, I finish with 600, 1000, and 2000 grit wet/dry automotive sandpaper. I just lay the sandpaper over the plate as backing. My stones are flat and slick like glass.

That 220 can chew through any stone like a chainsaw through pulpwood when using pressure. But with light circular strokes, it's surprisingly gentle, and avoids scratching. I never touch a razor to either side, I much prefer the continuous grit DMTs for that. But it's KILLER as a lapping plate.

I have the 8"x3" 325/600 version of it and it does the needful. I cannot seem to find it right now though. It disappeared on me.

I have been using one for lapping plate for at least a year. Wicked fast in comparison to continuous plates. Very generous size makes it a pleasure and light weight makes it nice under running water.

Matt. I noticed stripes when using but they are pretty superficial. Anyway, I always follow up lapping by rubbings stones together to get surface like I am use to. Takes just a few seconds.

BTW Glenn,
When I got mine I paid about 149 US dollars and would not part with it, holds up very well. 99 bucks is a great deal, you will love it.

I compared it to the continuous plate and really didn't find it to be much better. It still wanted to stick to the higher grit stones. Got the job done in any case.

I rarely use any plate on stones beyond 2k as i don't like finish once stones are flat. I just rub lower grit to higher grit and so on and rarely go out of flat as I do this each time I use stones each day.

I am sure you are in a different league as your specialty requires.
