Same. I broke at least 3 shafts when I started, spending hours trying to get them straight. May sort of be starting to get the hang of it...
Oh, now I want to try wooden dowels. Red oak is pretty cheap at Lowe's, but tends to have lots of grain violations. So much straighter than the bamboo I have, and softer bends..Forrester's shafts would be way better and still a good value.
Those Korean and Japanese fletchers somehow get the bamboo dead straight, but I'll probably just make crooked arrows that hopefully spin true.
