Thread: Lapping with dmt325

Hello new to honeing, got a question about lapping with my dmt325 I use it on my Norton 4K8k it leaves grooves in my stone when I try to flatten my stone. My question is will the those scratches need to be buff out or is it ok to hone the razor on the stone? I've SCEEN video showing the dmt325 as a nice flattening device. Thanks D.

Some scratching always will happen and it won't harm the function of the hones. If your DMT is new, then the scratches will be excessive because the plate's diamonds are of variable height and the tallest ones are causing the bulk of the scratching.

This can be mitigated by rubbing a piece of steel over the plate to knock down, or off, the tallest diamonds. The shaft of a long screwdriver works well for this task.

I wouldn't worry about the scratches on your hone. I lap with the dmt dia flat which is an xx plate. The scratches never effected my honing as the razor rides on top of the scratches.

If it bothers you or you think it affects your honing. Utopian gave you the magic fix.

Check this thread from 2009. Not a new question...

Right on thx again it was really concerning me with the scratches will continue using the dmt

Thx again appreciate the info. And thx for the thread. ����

Echoing Ron (Utopian's) suggestion to break the DMT in with a plane blade, chisel, or a long screwdriver shank. Also, when lapping I've always used mine under a light stream of running water in the sink. Helps remove the swarf and adds longevity to plate and hones I think.

Agreed. I consider this to be an absolute necessary.

Thank you, I just took a shank of a screw driver to the plate feels much smoother now. Thanks again.

Agree, with all said, one thing I have done is vary the use of the DMT 325, on my coarser grit hones, and I use a slightly worn in Atoma 400 plate. Both give very similar results. I asked a question quite a while ago, about the scratches left, and inquired whether a Atoma 1200 or W/D paper might leave the hone smoother. I was quickly advised, and correctly so, that the 1200, are no good for hones as particles of diamond can break off them and wreck your hone, So, the DMT 325 is fine, and an option is the Atoma 400. I like it personally.
