RE: Fletching Glue
Fastset gel and a good CA accelerator works perfect for me on aluminum or carbon.
I pour a little of the accelerator in a small cup thendip a Q-tip into it and wipe down the shaft just prior to placing the clamp in the jig. I give it just a light press down and it's bonded instantly.
Been doing it this way for years, helical or straight. Works perfect every time.
