Reverse bracing to apply sinew.. question

[TurtleCreek]

  What about Wisconsin in the midwest Pat B?

[PEARL DRUMS]

I have two sinew backed bows I have kept around for myself. One is hickory and the other is osage. Both are 64" long, wide flat bows, and both are 50-55#'s. This is by NO MEANS a discredit to Pats observations, just my own add on's. I have never noticed either bow act or shoot differently in any weather I have had up here. If it was, it was so subtle I didnt notice it. I used TBIII glue on both, Im sure that plays a part.

  I also plan on using TBIII.  Will the sinew backing still pull the bow into reflex slightly if I use TBIII?

[Pat B]

Probaly not pull it into reflex but you can add reflex.  All of my sinew backed bows are made with hide glue. TBIII would make a big difference how moisture affects sinew but I don't think you get the same performance with TBIII as with sinew/hide glue. I've never used TBIII for sinew so this is only a guess on my part.

My sinew backed osage bow has nothing more than 8-9 coats of Tru Oil over it. No skins or rawhide. The TBIII and finish seems to work perfectly together. My bows were sinewed with 3" of reflex pulled into them. I dont believe the sinew retracted enough to matter. Im guessing TBIII wont let the stuff move anywhere. Both bows are about dead straight now, thats after thousands of arrows.
