I typically use the Hegner for Puzzleboxes, but, the Hawk BM series claims to go 2.5", and have a longer stroke, so I thought I would give the Hawk a try and max it out. Here I use Padauk glued to Maple, and am using the Pegas #3 from a batch Hawkeye graciously let me have to try out. The kerf on the Pegas is pretty freaking tight for staying true at 2.5", so this is a very very good test. I did have to switch out "Thumb Screws" to find one that wasn't oriented in the down position when tightened (or I wouldn't have had clearance).
I love making these puzzle boxes, I'll post the completed box if I don't mess it up.
