CNC Mill

Using my CNC mill for some extra details.

Rather than chance clamping the plate that attaches the vertical stabilizer at the front with c-clamps, and inviting the obvious mis-alignment problems, it works out better to scale the pilot hole (1/8) pattern on the horizontal stabilizer (2-3/8 x 3) and use the mill to drill pilot holes in the attachment plate.

Then it's a snap to just cleco the plate in place and run a drill through the holes, one at a time, to size them for the bolt.

The first shot is the best screen shot I've been able to get of the software I started to write as curiosity project when I was recuperating from a little cardiac adventure back in 98. I've used the software quite a bit on this project and actually dusted off the wormy source code to straighten out some bugs with milling circles.
