Flight bow failure
« on: August 28, 2018, 09:29:16 pm »
Been playing around with this design specifically for flight Archery.  It shot super fast but I may have pushed it too far. Here's what it looks like after it turned inside out on me. It was 60" 50# @ 25"...ish Sinew and Pacific Yew.

Hehe that's a funny one DC. Nice try Mark. I've seen Ed do them with sinew backing and horn belly. Always impressed to bageebeis out of me.

I bet the horn belly would help and I lost too much heart wood on tillering I think. Wider and flatter for the next one. That did sting a bit and sure gets your attention quickly  :o

That is nasty.  High reflex bows can be very touchy especially at first brace and any sideways bend has to be dealt with right away

Well at least the sinew came off pretty clean! Sorry for your loss.

Did the sinew come off or did it split the wood?

When the bow turned inside out after the shot, the belly failed as there was nothing to stop the tips from continuing forward. I pulled the sinew off myself. This was a very unstable and sensitive bow and I was shooting it at a fairly low brace.

Sinew will pull a weak bow apart. I tried to glue up the crack but it pulled apart again.

Definitely some power in sinew and I laid it on pretty thick with a high crown for that one.

Wow!
I've had sinew pull apart but I don't think I've had a break like that.
But I don't push limits.

That will happen with a narrow tip contact recurve. I had that happen the other day with sinew backed juniper. 60" long with 5" reflex. 50# @ 28". In my case the low brace saved it from breaking. It still shoots fine. I had just added little horn nocks that increased the recurve just a tiny bit and made this happen. I got home and filed in new nocks 1/2" below and it's back to stable again.

Eric, my most used personal bow has huge cracks like that all up and down the sides. 49" sinew backed juniper 25-26" draw 48#. I have shot it thousands of times over the last 3 or 4 years. I started to see little signs of wood cell breakdown on one section of the limb finally but have never had a problem with these sinew cracks except they are ugly.
