first erc stave..very clean no knots..62 inches long 1 7/8 wide tapered to 5/8 at nock for now... My question is...how far would you till bow before backing it..never done a rawhide backing, done plenty of sinew jobs and that is what I am leaning toward.. I am thinking I can longstring till to about 18 inches...maybe 20..I do not want to brace bow till backed...had a maple backed erc board bow blow bracing after I long tilled it..it was stressed to max r/d design ..ended up being a pin knot in backing that blew... was trying to build it too heavy also..lol...if you aint breaking you aint making..lol...
