Im curious....why would you opt for the taper tool over the belt sander? Not sure what your jig looks like and how you have it orientated to the sander, but sanding ANY taper is by far the way to go! I have a taper tool....it began collecting dust once I got serious about making wood arrows....and I use Surewoods (fir)! A taper tool (at least mine, and its a good one) leaves a nasty, choppy taper...its the grain of fir. Sanding is the best option for uniformity. Dont give up on your sander and jig!
