I have used small rubber O-Rings with conventional blades for many years now to tune them for my bows. Never had a problem with them yet. I guess it would be just as easy to heat them up & turn the inserts. I just never did it because I have never had any problems with the rubber O-Rings!!

I went to the local hardware store and bought snall rubber o-rings. They add maybe 1 grain of weight and you don't have to worry about the teflon tape (some tip) throwing the balance off by getting to much on one side. They will allow you to line up the blades with the feathers.

I use dental floss and wrap it around the base of the broadhead..

Hunting with a bow brings about a different challenge on every hunt!!!
