? for math experts
« on: June 02, 2013, 09:32:00 PM »
Looking to build a jig for point and nock tapering fir shafts.  My question is am I looking for 11 degrees off the edge of the shaft or the center?  Planning on a simple piece of wood to butt the shaft up against and trying to figure if it needs to be on the 11 degree mark or set back 1/2 the shaft diameter?

I'm certainly no math expert, but the center of the shaft and the edge are parallel to each other.  So 11 degrees will be the same off of both.

I concur.
No need to complicate things.

An other way to think about is, whats the hypotenuse. And set your jig to equal that dimension.
