I do mortises in cherry .1" at a pass, cutting at a good clip to help prevent bit burns, not enough cojones in the spindle motors hangy-downs to cut much deeper. :)
I was nicely surprised the other day though, I took the bearing off a 1/2 cove router bit, laid that newest big diamond disk from dermel against the face of the carbide and polished it a bit, and then used it to carve, with minimal burns, the finger grip relief in the back of the drawer pulls for my entertainment center. 10 of them, but only one side for the doors, toward the hinge side of the door. I didn't figure I had the rpms but it worked fairly well except when attacking the end grain in dig cut direction at the right end of the cut, there I had to slow it down and shave less than a thou per edge pass to stop most of the splintering. And that of course is where it burnt a wee bit. I fixed upo my web page to take less bandwidth, see at <http://gene.homelinux.net:85/gene/E-Center/web> But I'm about frozen out, I can't work wood in that variable an environment, its not insulated well enough to heat effectively. Warpage is the keyword, I can't keep ahead of it. Nor can I apply finishes at 40F, the best I could do yesterday when I said to heck with it. Get over this *&%^$# cold, and start insulating it I guess. Bring money I would use for toys. 2" styro is now almost $30 a sheet around here. The 2" Blue stuff seems to have disappeared, and I recall it was rated about double the R that the styro stuff is. 1 sheet does one 2x6 worth of wall when cut in half and stacked 4" thick, and there is 56 feet of walls=28 sheets, with some leftovers to start on the 16x24 ceiling. I figure about 40 sheets to do it right. $1600. Add another kilo for installed heat. It will wait for warmer weather thats for sure. :( >2) We never got good detailed information about the bug before, and were >never able to reproduce it.
