Bohning has released a version of its Tower fletching jig that is compatible with spin vanes. The Mylar Tower removes the guesswork from positioning tape-on vanes with precise 120-degree placement, and comes with centre posts to fit multiple nock types and two post rings for varying arrow sizes. The red clip is adjustable to fit left- and right-handed fletchings, while the bars on the arms make it easy to line up your vanes and cut the tape to length.
