Thread: Lapping Shapton Glass Stones

Yes, or sandpaper on a suitable flat surface.

The large lapping stone Lynn was showing I've never seen or used. I guess it would have to be lapped on sandpaper. The normal size stone from Norton or Naniwa...the DMT or similar media.

The best option, dollar wise, is the DMT325. The next best option, IMO, is the Atoma 400 (my choice), and finally the Shapton DGLP, which I have, but really don't use because I have the Atoma.

A DMT325 will do the job for you. An Atoma 400 will give a little more smooth surface and a more precise flat surface. A Shapton DGLP will give the more precise surface of an Atoma, but cost $379.00.

Try not to overthink it. They'll all work!! (Well, except for the Norton and Naniwa lapping stones IMHO) which I just don't use. Just how precise do you want to be and how much are you willing to spend?

I don't have the Shapton DGLP, but I prefer the Atoma 400 over the DMT 325. I think there is value on the Atoma ($55.00 more).

Like Sirstropalot said, you get a truer plate (flatter= >consistent honing)

The Atoma is aluminum plate and weight less (much less). Making it easier to use and less likely that you drop it on top of your shapton and brake a corner or something.

It last longer than the DMT 325. And when it wears out the replacement cost is $75 (I think) (it's a sticker that replaces the old one on the aluminum plate)

It's easier to use, doesn't stick to the stone like the DMT and it removes more material than the DMT with less effort.

That's my 2 cents!
Double O

Many many stones and hones lapped and many heels re-contoured, and edges restored by far the most used versatile plate I have is the DMT 325,,, Mine is what is called "Well Worn" and I have no need or intention of replacing it,, Best $39.99 I ever spent in 2008

Oh yes I have others, one that cost almost 10 x more, bought it when I bought the Shapton 30k, those plates, they are not "Well Worn"

I have the Shapton GDLP - works great but it's pricey. Make sure to do figure 8's - it works much better than just going in circles or linear motions.
