Thread: Small green hone.

Got this in the mailbox today, very hard, and hard to lap. You can see where I have spent about ten minutes trying to get the dish out, and have given up for tonight,

I think I know what it is, but would like some opinions.

Will be interesting to see when they will be fully lapped

Seems to be a Llyn Idwal.

Here are the latest photos after lapping on my 32" lapping machine.

Looks a bit like an LI of the 'grecian' variety to me at first glance.

Love that lapping machine of yours, BTW - have been thinking of making one for some time...

How hard is it? Slurry? The back side of my yellow/green thuringian is marked like that.

All things being relative, I've spent ten minutes just getting ready to lap a hone.

That awesome machine of yours spoilt you fast it seems!

I got no ideas on the stone. Although I sometimes wish I did.

Look if the stone in the middle of this picture looks like your.

It's not slate or thury/Escher type. When I first took it to the DMT 325 it was very hard like a novaculite stone, it slurrys very thick like paste. Although after getting it on the lapping machine I found out it is not as hard a a translucent Arkansas stone. I was able to lap this in 5 minutes compared to an Ark'y that would have been 2 hours.

But it is still much harder than slate.
