Title: sinew
Post by: Slickhead on July 24, 2019, 10:23:38 PM

curious on sinew
how much does it take to do a 64" bow?
Also can you use tite bond or is hide glue better?

are there alternatives to sinew.
Looking  to add strength or durability.

Looking at getting a u finish and adding some protection
any help appreciated

Fiber glass, self bow, tri lam, what?
Who's U finish bow are you getting? the most important question.
sinew is not for a novice and hide glue is what you should use. Lot's of work and time waiting for it to dry.
Rawhide backing

Sinew adds a lot off mass a 64" bow depending on the front view is a little long ,I have a friend that makes Molly type bows and only sinews the working limb part of the bow on longer bows & works out for him but sinew in general works better on shorter bows below 60" sinew needs to be put under heavy stress to over come the mass issue but if your just looking for back protection the real thin rawhide like is used for drum heads , goat rawhide it adds a lot of protection for little mass and can be gotten for cheap I got a whole hide for under $30  and raw hide doesent require re tiller or adds draw weight !

I Backed a couple board bows with really thin goat hide and it worked great.

The easiest way to increase performance and durability in a board bow is to add a hickory backing, as long as the back of the bow is flat. TB glues work well for this and you can add 3" to 4" of reflex at glue up.

I agree.  I wasn't seeking performance with the rawhide but rather protection.  It cost some performance but it's still shooting.
