Tex, I shoot aluminum arrows. Had to make one set of woodies for one shoot that I attend once a year. Get the notion that this is a one-time deal? The guided only work for 11/32 diameter cause that's all I ever intend to make. I like Eric's for simplicity. It'll take any diamter. Like Eric, I don't use the stop any more. Even before I'd made a dozen, it was EASY to eyeball the length of the tapers. Basically I'd eyeball the skinny diameter at the end of the taper, since you don't want a point.
