RE: Working with aluminum shafts - ?
Ditto what Art said, he is right on with all of it. Agree....Easton only, preferrablyXX78s (w/uni bushings).
Regarding inserts...what I do is put the insert just barely into the arrow, and heat it up over a propane torch...rotating it to evenly heat it. Then put yourferrule-tite stick on the insert, and rotate the insert in it....it will melt uniformly around the insert. Push the insert down onto a paper towel, and seat it into the arrow, then rotate it on the paper towel, wa-la....ready to go, with excess glue wiped off. You'll know when you get it hot enough, it doesn't take much....and you can't possibly melt the aluminum unless your a complete idiot.
I don't know if I'd waste the $ buying an arrow straightener initially. I have one, and they can definitely be straightened back if its not too bad, but honestly unless you shoot a ton...you won't use it much. Might be better to spend the money on something else. Fletcher, hi-speed cut off tool, etc.
Good luck!
