I'm betting that no one has the balls to try the tip i'm going to mention... I've mentioned it before and everyone cringes.. It's on my bow building video and I have gotten many replies on how i should do something different, but here it is.
I use a 1" wood chisel to remove the tape off of my glass. I used to use the cheapest tape that I could buy and then use the chisel to start peeling it and then again when ever it would tear.. some times it peels, sometimes i would have to shave the tape the full length of the limb. When I switched to Bear Paw glass, I had to switch to frog tape.. so when I went back to Gordons (currently using Gordons) I just stayed with the frog tape.
I've had employees and friends do this to help me out. In over 2500 bows, i have yet to have anyone scratch the glass more than what would sand out with 220 grit. I doubt there has been more than 5 or 6 scratches the entire time.
Now, if you can't be trusted with sharp things or aren't very talented, this may not work for you.
No tricks to it, just always lay the chisel flat on the glass.
