Sinew processing

[Newbreedarcher]

So, I am processing sinew for the first time. It is leg sinew, fairly long(12-15") I have processed 5 or 6 pieces and they have rendered nearly on half of an xl ziploc bag. My question is, is how much hard sheathing is normal to have left over? I have a large amount of it left. I am saving it, I am under the impression I can use it to make glue. I have pounded the sinew to a point it is separating as much as it seems as it will without damaging the fibers. Any advice would be greatly appreciated.

Pound until all the hard stuff is gone. It is easy. You will know. It will beautiful white threads.

how about processing back sinew?  does it need pounding too?

I just scrunch back sinew between my hands and pull it apart.

Like Pat I generally just scrunch it up and start tearing it loose. If the back membrane wasn't removed pounding the heavy top side will help to break it loose. Also even when part of that membrane is remaining you can tear a few strands from from the center and work out to the sides. Usually the membrane will stay intact and the center will pull loose from it.

I've processed a pretty fair amount lately. What you should have left over is just some papery stuff. That is the outer sheath. This is what you're trying to achieve. There is only 4 deer leg tendons here. Patrick
