Virgil,
I developed the Bow Bolt system for the exact reasons you mentioned. There are a lot of good systems out there, but none did everything I wanted them to do. The Bow Bolt does, but proper installation is very important. That's not to say that it is difficult, it's not, but care must be taken in getting the best glue bond possible when installing one.
My theory was that if you replace wood with stainless steel (assuming a good glue bond) the handle should actually be stronger than if it were all wood. Most woodworkers will tell you that the glue joint is stronger than the pieces being joined and where care is taken, this is true.
Having said all of this, there have been bows that HAVE broken after installing a Bow Bolt and upon examination, the reason has been the same in all cases. Poor glue joints around the Bow Bolt or "dry spots" in the glue joints of adjacent accent stripes. In two instances, the fault was found to be epoxy that didn't cure properly; probably due to its age. It was found to be two years past it's shelf life.
There are detailed instructions on my website (WWW.Warrenarchery.com) which emphasize the importance of being super clean during the process, but some tend not to read the directions.
I am still shooting all of my prototype Bow Bolt
bows (some are 4 years old now) and they are all doing well. Some are solid wood, some are action wood or dymonddwood, and one is solid micarta. I know of several others that have been dry fired because of broken knocks and one, an 85# bow with a solid Cocoabola riser that was built as a "test bow" that was dry fired on purpose and all have stayed together.
If proper care is taken during installation, there should be no problem with breakage.
