The PP Mini-Tarus came with what looks like 1632 tubes to tie on the bands. First slingshot used without clips or some other mechanical system to attach bands. Used some flat ribbon ties to attach the bands I cut. Probably over kill in terms of wraps. 7x, tuck the tail, 2x, and then lock. Played around with the tubes. Looks like 3-4 wraps plus 1 over the tail before locking will hold. Anyone recycling their broken 1632 tubes or using fresh tubes to tie on bands? Minimum number of wraps? Bad idea to recycle used tubes? Would need to purchase fresh 1632 tubing. The costs relative to the ribbon (~$12/10m v. ~$2/20m) is huge. But tube looks like it can be reused a few times. Maybe fewer wraps needed.
