I have done the fiberglass handle myself. We followed the instructions in the PA magazine. I will tell you, It is not easy. It took me and a fellow tradganger about 5 times of trial and error before we got one right. But we started with two billits. Not with a complete bow that we cut in half. Did this make it harder, Im sure that it did. Problems that we ran into were, Too much wiggle room, one the bottom limb wouldn't say in the sleve, one was not strong enough, One got glued together (took a comealong and a hammer to get it apart) Those are the types of problems we ran into. Here is what I learned. Be sure to wax one end REALLY good, you can use a drill and make a "snap effect" to know when it was in place, the use of single strands is the key.
We took the two billets, which were about floor tillereing, cut the angle on the handle part. The we placed them in two vices alining the handle ends as close together as we could (one with wax and one not). Then we took 20 min epoxy but some on the bow and took single strands and wraped them untill the handle area was completly covered in single strands. Then we put more epoxy on the handle and took wraps the size of the handle that would only go around the handle once. You could see the epoxy seeping through from the underneath. We would still apply more epoxy after each wrap. We did 3 full wraps. After the full wraps were appled we went back over the last layer with more single strands like we did to begin with. We let it dry before removing the limb.
Maybe on the next one we do we will do a buildalong on here. Hope that this helps
