just finished my first batch of arrows, using the Jo Jan multi... well, actually, I used one station of the Jo Jan multi. I used the fletching tape and immediately discovered that one clamp is all that's necessary. The clamp worked well. As it happens my son has a Jo Jan mulit as well, but he got his used along with a bunch of odd extra clamps... some straight, some right helical, some left. the other night we decided to cut out Jo Jans down to three stations each and split up the clamps so that each one had a right helical station, a left and a straight. The tool will still be nice and stable on the bench and very versatile.
