My insurance agent has a KOA campground in California and brought back some manzanita burl/root and sliced it up with his chain saw then called me to see if I could make him some clocks for their store at the camp site.
I used a 3" fosrtner bit to bore out the pocket for the clock works. Long process doing this as it is a hard wood and it took very little time for the bit to heat up.
Pocket depths ranged form 3/4" to 3". For the big thick clock (almost 4" thick) that I saved for the last one to do, I did about 1/2" with the fosrtner bit and then changed over to a router with a straight bit. It took me about an hour this way vs what I figured would have been several hours the other way.
Finish coat is several coats of clear lacquer spray.
And NOPE none of the work was done on the CW..
