Please have mercy and give input on my glass bow project.

<< < (2/2)

IrishJay:
To ask a more general bow building question, what are the mechanics of a back overpowering a belly? I understand that its caused by the tension strength of the back being greater than the compression strength of the belly. And I understand that it causes crushed fibers in the belly. I'm just a little fuzzy on the how and why of it.

Also is it something that would happen just drawing the bow, or is it somehow related to the recoil of actually shooting the bow?

Pat B:
Woods are stronger in tension than they are in compression. The reasons those bow companies discontinued the glass backed wood bows is the bellies couldn't take the tension of the glass backing.
 Did you use a strip of bow glass on the back of your bow? What binder did you use for the glass?
Over the year, here on PA we've had this discussion quite a few times. We are here to build wood bows and to learn how to successfully build an all wood bow without an artificial crutch. It can and has been done and I might add with some incredible results. Just look at BOM over the years.
