Eman, Regarding the sled. I made the sled out of some plywood as you can see. I made it to cut at an angle (similar to that of Bingham's wedges).
Basically, I just cut 2 inch wide .375 thick pieces of wood, (about 8 1/4 long for this specific bow), tape them in the sled and slowly run then through a drum sander (performax 10-20). I generally use a 36 grit belt and after 6-10 runs through when the tip is paper thin, you are done.
