Osage Sinew Backed question
« on: February 17, 2010, 11:52:00 AM »
I'm working on a osage sinew backed recurve. The bow is 60" long,46#@28". I still have a little bit of tillering to do to make it perfect. I'm gonna lose some more weight. I really did not intend for this bow to be this light. Do you think taking an inch off each limb would bring the weight up 5-10 pounds even though I'm taking some of the curve out. The curve in the limbs right now, is just enough where the string barely touches the belly at brace.
I'd appreciate a little advice,
Dan

Will you post pics of the bow and the recurves?  That will help.  You can shorten the bow a bit to increase weight but I doubt 10#. How many courses of sinew on the back? How long have you allowed the sinew to cure?

I'd just add some more sinew instead of making it shorter.

It has 3 courses of sinew. It has cured for 5 months. I already put snake skin on the bow. I'd hate to have to pull that off to add more courses.
Thanks,
Dan

Pike each tip 1" and see where you are. You might even be able to remove another inch from each tip but without pics I can't say for sure.
  It always pays to be sure a bow is well shot in before making it perty. What did you glue the skin down with?

Does it bend in the handle?

It does not bend in the handle and I used hide glue to put the skin on, so it would not be to difficult to remove if I went that route.

I should mention the limbs are 1 1/4" wide then taper to 3/16" nocks. The recurves are also static.

I would not shorten it.  Most of your weight gain is going to be from loss of leverage (ie. stack weight) and not necessarily do anything to make it a more efficient bow.  I'd probably just build another bow if I thought I needed more weight.  Life is full of lessons learned.

Sounds like a sweet recurve to me.
