Title: when sinew backing can i layer 3 types of sinew?
Post by: ravancroft on April 11, 2015, 11:59:40 pm: This will be my first time backing a bow and i am using sinew, i have enough back leg sinew for two layers of a backing and enough backstrap sinew for one maybe two layers of sinew. Would i be able to layer it leg, backstrap, leg?

Also, I prefer leg sinew for bow backing. But to answer your question, I don't see any reason why you couldn't use sinew from different species. Unless there might be different stretch, recovery or shrinkage rates. Probably negligable though. I would choose one or the other; leg or back.

Post by: MWirwicki on April 12, 2015, 04:21:26 pm: Cool PatB! Never tried mixing leg and back! I've got a bunch of back that I don't do much with except for bandaids and wrapping.

Post by: crooketarrow on April 12, 2015, 05:26:04 pm: I've mixed it up 2 times before I saw no differance.
I once used moose and did'nt have enough. So I put layer of steer first covered with mosse.
