I shoot
Beman ICS Hunters and Sonic 100's.

I screw in the broadhead and spin it. If it wobbles I put it in a pan of hot water then rotate the broadhead to smooth out the glue. I will line up one blade with the cock Vane. Then spin again. Up until now that has worked fine for me. However, if I get one that still wobbles, I assume that the end of the shaft needs squared. Up to now I have not had to borrow my friends squaring tool.

At least that works for me.
