Sinew backing: to chase or not to chase?

<< < (2/5) > >>

bradsmith2010:
   im just guessing, but alot would depend in the draw weight and how far you intend to draw the bow,,as to how much violation it would take,,
differnent woods are just different,, Im pretty sure Jim Hamm recommended following a ring, thats how I did it most the time on osage,, but sometimes if the stave was not enough to make a bow I made successful bows with violated back,,thinking a couple extra layers of sinew would work,, and did,, there may not be a definitive answer,, and lots of variations may work,, I like the way Pearl looked at it for a good starting point,,
   try it both ways and see what you think,, keep notes and give good advice later when someone has the same question,, :)

Marin:
Okay will do. Thanks, I just wanted to make sure I wasn’t the only one who thought there was more “nuance” to this

Back violations is the only reason I ever sinew backed a bow. If I have a clean back ring I don't sinew back it. No need. No failures yet with violated backs, and sinew, and not at all gun shy to shoot them, but do it the way you feel most comfortable. Never used yew, or juniper.  I have used blue beech ,elm, black locust, Osage, and hickory with violated backs ,and sinew with 100 % success rate so far.

superdav95:
I have had success with slight violations in non critical areas on whitewoods with backing with rawhide.  In cases where I have to remove surface damage or just shaping into the right thickness for the weight of draw I want I’ll sinew back and also thin rawhide or snake or fish skins.  For yew I’ve gotten lucky with slight violations of the sapwood but I think bow design would be a factor too.  Like was said already most non rawhide skins other then maybe sturgeon offer only cosmetic covering to the bow back and won’t provide any strength really. 

wizardgoat:
. I’m not certain on the real reasons, but aside from yew and juniper being evergreen soft woods, and osage being a hardwood, there’s pretty big differences in the wood and why most keep a single ring for osage and violate yew and juniper. There’s not a big difference between the early wood and latewood in yew and juniper, probably because they grow all year round. I prefer to use pretty nice and clean wood for sinew bows, so violations are minor anyways.
