Justin , thanks for the advice ... always want to keep the peace...
Having built over 60 bows so far , about a third of them broke , most were OK, and a few were real good shooters...We only started using "cloth'' backings for a cheap camo for our customers who wouldn't "spring' for snakeskins ... one guy even brought me a c/net and said that's what he wanted... worked so well , we just kept using it ,never giving a thought that we'd offend anyone ....
You're right!!! No backing is necessary , but if you're 2K miles away from home on a hunting trip , that little bit of "insurance" is very comforting ...especially if such Primitive things as eating depends on your hunting skills ...
If being Primitive is more important here than considering bow building ideas and information exchange, I'll just mosey on over to a more "friendly " group...Thanks , bye !!!
