It looks like a short flat spot there to me but when I zoom in I don't see it. Waiting for the answer and post mortem pictures though.

Post by: gumboman on April 29, 2020, 09:07:00 pm: Bottom limb. It looks shorter and stiffer.

Post by: Stick Bender on April 30, 2020, 02:04:48 am: Top midlimb !
Title: Re: Bow forensics.....
Post by: Rākau on April 30, 2020, 02:10:25 am: I honestly can't see any point in the bend that looks worse than any others I'm gonna throw a curve ball and say it was something strange, like the handle or the tips.
Title: Re: Bow forensics.....
Post by: simk on April 30, 2020, 02:23:34 am: unless it's obvious they never break where you expect. In this case I would guess for the handle area...

It should be :)
Title: Re: Bow forensics.....
Post by: bownarra on April 30, 2020, 03:19:07 am: 8 or so inches up from the handle.
Of course barring any delams or dodge spots in the pau am!
I've had quite a variety of results with it as a belly. Some has been awesome but some takes far too much set for my liking. I've always backed them with either boo or hickory and have thought before that maple/ash/elm would be better suited to it.

Post by: bjrogg on April 30, 2020, 05:39:01 am: Do you have a unbraced profile? If this is a full draw picture. Although tiller is not perfect it doesn’t seem stressed enough to break. Especially being backed with bamboo. Did it fail in tension or comprehension? Was it something else, like a delam?

Assuming a straight, flat unbraced profile and no other problems. I’m going with center of handle or lower limb right below bottom of sheet.
