just backed a hackberry with hide glue and leg tendon sinew from two bison we butchered. its now drying.
ok my question to y'all with sinew back experience:
...some small gaps formed when the sinew dried .. Is there a recommended filler in those crevises other than tiny bits of sinew
and more hide glue? has anyone tried TB3? or any other filler that takes limb flex?
appreciate any thoughts!

I would add more sinew to the gaps. It will become part of the backing. TB glues are compatible with hide glue/sinew but it will only be along for the ride even though it will fill the gaps.

I posted this a while ago in the hopes of helping out those who struggle with the vagaries of sinew backing.

great info PatM,
good to actually see what you're doing
didn't think about wrapping it to compress it all together...makes sense.
you mentioned you wouldn't leave a sinew back bow without some covering, thin rawhide or other
What would be a reason other than "looks" ?
If i did decide to rawhide back over the sinew , how important is it to get any air pockets out of gaps between sinew ?
it would be hide glue laid down first, then a rawhide strip just a tad wider
and be wrapped with the same cloth strips?
