so last night I decided to make a neck caul to help in clamping the fretboard onto the neck. I usually put it in the go-bar deck, but I need
a little pressure this to make sure it lays flat (long story, don't ask).
So I got onto F360 and modeled a caul with a concave surface perfectly matched to the neck model (just did a solid subtraction on the two parts),
and then CNC'd it last night. Came out with a perfect fit, and now I can use regular woodworking F-clamps on it.
