Thread: Lapping Ch12k

I recently lapped a new C12k I got from woodcraft with my DMT D8C, I did the pencil lines. Lapped it in the sink with water running to reduce the sticking. It lapped flat in about 5 minutes. I checked it with a straight edge, several times. I did the corner and sides too. Has anyone else seen this phenomenom. I've heard it can take around 30 minutes. This stone was far from true when I bought as confirmed by my straight edge.

You could just have a very soft stone.

Unless you lapped it with a few hundred pounds of pressure at 1000 passes per minute...

LOL, I know. It just blew me away, I kept checking and rechecking, I guess I got lucky. It's quite smooth and true, I'll test drive it today. I have a razor that can use some tweaking, then hit it with the dia .50 and test.

A few guys have reported the same. Is it the large one?

Mine is the large one and it took forever with a DMT8C.

zib,

Mine is also one of the larger Chinese stones and I wore the diamonds off one end of a DMT8C with it. Apparently you are one of the blessed lappers.
May your gift transfer to honing.

Yes, it is, from woodcraft. it was definitely off when I got it, The D8C made quick work of it.
I was really surprised. I expected it to take a while.

I flattened mine with a Norton flattening stone. I then dressed with 1K Wet/Dry wet and it took awhile but it was way worth it. I rarely have to redress it.

Mine was the same way. Maybe 10 min tops. I though I did something wrong for a while but never had any problems.
