Title: Sinew Question
Post by: BrokenArrow on November 11, 2014, 06:57:09 pm
What is the best sinew to use to back a bow and for a short 53 inch bow how many layers are needed?

I've used deer leg and backstrap sinew, elk leg sinew and cow leg sinew. They all worked well. The longer the better for a smoother application.   I actually prefer the cow sinew I used because it went down smoother for me.
 I usually put down 2 thicker layers or 3 thinner layers to get a smoother back. It depends on the sinew you use and how fine it is shredded.

What would be the poundage increase on my bow with one layer of sinew and then a rawhide strip?
I think it is currently around 40# at 24 inches

Maybe 45# but that depends on how thick the sinew is. Why add the rawhide. It will only detract from the performance.

Rawhide was my original plan but I read that to keep the recurved tips you should use sinew. Do you agree with this?

No. Recurved tips don't need sinew to hold them.

So do you think going through the sinew option is worth it if the bow has very little chance of breaking, should I just rawhide the back if I am unsure?

What is the  bow type and wood? Sinew is always a good option for a shorter bow.

Osage 53 inches.
Is rawhide enough to hold most backs down?

the sinew could increase performance, and draw weight,,, helping the bow hold reflex also allowing the bow to be drawn to a longer draw,,,,, the rawhide will not increase performance, or draw weight,, and not really allow for a longer draw,, it will protect the back somewhat,, and that is questionable depending on the thickness of the hide,,

I just wonder whether sinew is worth the time and money? It is a short osage bow but 3 layer so sinew is not cheap.

You should be able to get 26" with the 53" bow if you bring the bend back to the handle. Be sure your back ring is pristine with that much bend.
