Smashed Sinew Backed Bow
I'd just done my final tillering, got my sinew backed Ash bow (51" long) up to 28" draw. I'd shot 6 arrows yesterday and it felt really good.
I was going to take some pics of it on the tillering rig which I've just made in the garage. Frosty morning...big mistake...crack bang.
Where the sinew snapped it looks dry and fibrous as if the glue hadn't really bound the fibres together. Anyone else managed to smash a sinew backed bow?
I was sooo looking forward to shooting it to.
I s'pose it's how we learn...

BTW it was measuring about 48lb...:bawling:
Not sinew. But a bamboo backed osage. It was a bad spot in the gluing. It's one of the reasons folks started using inflated hose to compress the glueup.
Why do they wait till you have all the work in before exploding?
Good you didn't lose any blood over it!

same happened on my first longbow attempt. Also bamboo and Osage. Bad spot in the glue made the lamination fail when tillering. It was repaired though and is now a working bow :)
Sorry to hear about the bow.
Was it Titebond you used afterwards? Using traditional glues, the sinew is soaked in the glue and when applied to the bow, much of this is squeezed out. How did you apply the sinew?
Yeh, I used the TitebondIII, it did seem to soak into and soften the sinew, I worked it into the sinew between finger and thumb for a bit before laying down each strand.
I think the real prob was I was too greedy trying to get too much poundage and draw from such a short bow!!??...then factor in that I'd just added a couple of twists to the string having waxed it to help bed the strands in...and then a frosty morning.
I think it was an accident waiting to happen.
I'll have another go, I'll start looking for fallen timber, I'll add a couple of inches in length. I'll try the hide glue this time...I was a bit put off by the thought of having it at 100degrees C, can it be worked thiner and cooler say 50 degrees?
Anyhow it's all part of the learning process, and at least I got my decent tillering rig built.
I was reviewing some threads about bow warming...but I think the frosty weather is just an excuse for me being greedy.
It will be good to have tried Hide and Titebond...the Titebond experience was pretty good, but it's a laborious process, I did 2 layers of sinew.
