Thank you. I've never tried any Ebony. I usually have local woods like Oak and maple, but I'm not much of a wood worker. It's tends to frustrate me. I'll need to get some new bits and put the big router back on the CNC, then I'll give it a try. There are quit a few woods harder than Purpleheart but I can't pronounce most of them.

I'm going to try some scraps of Padauk first, it's not as hard as the Purpleheart but it's harder than anything else I have.
