I believe it's 5 degrees for the point, and 11 degrees for the nock. If you can locate an already tapered shaft, you can use it for a guide.
When you get ready to start making arrows, nock should go on so that the grain is perpendicular to the bow. From the side, it will look like this ==========
The riff ( those v's you see on the shaft) should be pointed toward the point end of the arrow on top of the shaft. >>>>>>>>>>>>>>>>>>>>
Take your time, and don't try to get too fancy first time out.
Good luck!
