Title: Sinew backing a spliced stave (billets)?
Post by: Juniper on April 27, 2011, 04:19:43 pm

I have my eye on a couple of pieces of juniper that are approx 4-5" in diameter, they are straight, but not very long 36-40".  I was thinking of decrowning and splicing them together in the handle.  Would there be any problem with sinewing backing the bow at that point?  Wasn't sure if the spliced handle would cause any trouble as the sinew dries and hopefully pulls the bow into a little reflex.  Appreciate any thoughts.

When doing a splice can't you put a little reflex in the splice?

I agree with Polar Bear.  You should preload a bit of reflex into the bow blank, prior to applying your sinew.  Construct a simple stand to hold the bow horizontally.  Tie the center of the bow to the stand.  Apply sinew.

See pic.  Note simple shim under the middle brace of the stand which preloads the bow into the reflex.

Unless the wood is naturally reflexed, when I'm splicing I always glue a couple inches of reflex in.

   I really hard to saw the joints to have the reflex some people just can't get it. Just saw it straight then use a form like you see. I ratch strap them down and ad my own reflex. This way your reflex is not jist in the handle. If or joints glued up right adding the reflex is not going to hart it.
