i'm working on a blk. walnut bow with a little bend in the handle. i want to add reflex so i added some sinew with knox and it did'nt appear to do anything. so i couald'nt wait any longer and started to get it to brace height today. but i think i might make some hide glue and add another layer of sinew and see if this will work. does this sound reasonable or not? and what wall mart dog treat is best used?

Did you have the bow in reflex when you sinewed it? I use 2x4 blocks to raise the tips a bit and the handle pulled down and tied to the form with thin string that can be removed or cut off later. How long is your bow? If too long the extra weight of the sinew and glue will defeat the purpose. You can add reflex by clamping the stave to a reflexed form and heat it well. After it cools completely (preferably over night) most of the reflex should remain. Don't put more than 3" of reflex in it either because it will overstress the wood and take more set.

If you tie it up into a little reflex and then apply your sinew it will hold a little reflex after the sinew and glue have dried. It works like gluing up a laminated bow that is clamped into a reflex to start with. Also over the years as the sinew and glue continue to cure it will keep drawing the bow into a tighter reflex. In the past I have had to go back and re tiller a bow to reduce the increase in draw weight.

Look's like we were a minute apart, Pat ;D

no, i did'nt, but maybe i can take the sinew off and start over!?

Are you trying to get sinew from a rawhide bone treat? I've never seen a sinew dog treat. ??? How long did you let the sinew cure?
