I'm ready to start making 6 mills for holiday gifts, all based on crushgrind (or Woodcraft clone) mechanism. In the past, I've always included a mortise and tenon of various designs between top and mill body. Craftsupplies has an instructive video which simply uses the 1 1/16 body bore as mortice and the "base" of the mill head crush grind mechanism as the tenon. Of course, this method greatly simplifies the build, but ??. If the roughly 1/8 "tenon" length is insufficient in daily use the mill is NG.

Anyone with experience?
thanks, Bill
