Another Lapping Thread....

Yep the Arkansas will get it there, pretty cheaply too :)

I use the DMT 120 for heavy work then the 325 I have tried the high polish, but honestly I haven't ever found any improvement, but YYMV and you have to try it to know for sure..

I was really into the High Polish on all my Hones right up until I bought the insanely expensive Shapton 30k and DGLP and realized that the highest grit (Proved) hone uses a 325 grit for lapping.. After that I really never worried much, but it is something you have to try for yourself :p

There is some good stuff about lapping in the archives from "Mparker" you should search it out

I got the Atoma 1200 for my Jnats and tried it right out of the package, as many said they had. It left a lot of scratches on the stone. I then used an old meat cleaver at a steep, maybe 45 deg, angle and ran that over the Atoma and made sure I got the sides and ends too. It took about 3 times of several passes, but the 1200 now puts a finish on stones without visible scratches that when looked across at a shallow angle has the shine. If I want a real burnish, like Glen said, I use a Black Arkansas. I'm really liking the Atomas. :D

Thanks guys, I just dropped $340 on a coticule so I'm going to wait a day or two for the stink to wear off then pick up a few lapping plates based off what you guys are saying here!
There are some members here that have such nice stuff it makes me sick and poor! :)

Anybody know what company makes the Atoma and their standpoint on lapping stones with them?

Lemur,
Here's a link that gives a description of the Atoma and the measured levelness. I can't tell you who makes them because the packaging on mine was all in Japanese. Atoma Diamond Plates - Lee Valley Tools

Howard :)

The Atoma maker is Tsuboman if that helps.
I don't know their standpoint on lapping stones, just mine. :)

Thanks but I wanted to know what the makers them self says about it, found them here; http://www.tsuboman.com/handtool.htm
They electroplate the diamonds to the film, that is from a technical view a weak setting, a sintered diamond plate would last longer for lapping stones, but would be more expensive.

I use DMT plates right now but will get an Atoma to try next time I need a new one.

From a practical point of view, however the raised pimples on the Atoma prevent the slurry from undercutting the nickel easily as with the DMT's. This is why even the 1200's last for years as lapping stones.

So i'm doing it again.... second guessing my purchase. Seems like I can make a decision on a razor no problem. A soap/cream/aftershave, no problem. When it comes to hones it's like.... i need people to make the decision for me these days. Maksim picked my jnat for me, you guys picked my 1k for me, jimmy picked my new coticule for me..... someone pick my lapping equipment for me?
