I've been using the hand method for years and it has worked, but I have a couple sitka shafts I just can not get straight, yet, I ain't giving up ! I tried heat, with an alchol burner, keeping it up off the flame, just enough to get the wood heated up and then trying to bend them back in shape. There giving me a fit.
I had thought of one of the straightners, as an alternitive for some of the "worse" shafts. I will keep after it though, I ain't done yet.
Thanks for the help guys.
