What tapers do you want to do? I use a Tim's Taper Tool. I have it mounted on a 4"X36" belt/disc sander. I can do the 10" taper, the nock taper, and the point taper. I have been using it for 10-12 years now. I really like it. 3 Rivers has them as well as Amazon. I buy parallel shafts by the 100's and straighten them, taper the nock end, and do the 10" taper. Then I go through them and weigh and spine them then group them. You will lose 0-2 lbs. doing the 10" taper. I hope this helps you.
