Title: Strongly reflexed bow turning inside out!
Post by: WhistlingBadger on November 27, 2025, 08:31:29 pm
Well, dang it!  I've got a juniper/elk sinew bow on the tree.  The sinew put about 6" or reflex into it, which is great and should make a hard-hitting bow.  The limbs are a little snakey, but I got them unkinked enough that the string crosses the center of the handle.  But today I got it bending to about 8", put a string on it, and the thing turned itself inside out!  Is there any way to make it not do that, short of peeling off the sinew and starting over?

What brace height did you string it at?

You need to get it to the point where it can be strung at a decent brace height, at least 4". If you try and use a loose string or a low brace height even a moderately reflexed bow will want to "flip".

I was just about to say what Hamish did. Highly reflexes bows pretty well need to be taken to full brace skipping the low brace stage.

Definitely do not take sinew off. If you need to make it bend more just take more wood off the belly very slowly. It is very very easy to remove too much wood when tillering a high reflex juniper bow. Once you get past that snap back point the bow doesnt have as much draw weight as you think. Thats actually one of the things that makes sinew backed juniper bows so darn powerful haha. Kinda straightens the draw weight curve out a bit.

Interesting.  So the solution is to brace it higher.  That's counter-intuitive!  I'll give it a shot.  Thanks, guys.

And tiller slowly, Pierce.   :OK  No problem there--this thing is so snaky I think I'm going to do most of the tillering with a cabinet scraper.
