Success!! today with a fresh cut 18 " hickory billet. My 4th attempt and this one is straight as a arrow and right down the middle. Perfect. Changes made include: I went to an 18 " X 1/4th" in bit (lots stiffer than 12" X 1/8th I was using) , I worked with wet fresh cut hickory, I followed the many excellent posts advice from Possum and Finnagan cleaning flutes, etc and I used a level to help trace the progress after cutting the face perfectly perpendicular to the billet long axis. And the big thing was that I was lucky. I've left the bark on to control/slow drying some ?, and painted the ends to help prevent checking. Any tips on the drying, curing process? and how to work a 3.5 in billet into a much smaller handle. I recognize that I have a chance to subtily impact blade striking angle some while I shape the handle, any suggestions?
