Thoughts on sinew on black locust

<< < (2/3) > >>

Pat B:
I agree with both Brad and Pearlie about this. But...for someone not familiar with different woods or methods a 63"x1 1/4" locust bow IMO doesn't fit in the parameters of a successful bow build. And, trying to save an already over strained bow could give false hope to a newer bow builder. If he just wants to experiment with heat treating and/or sinew backing then this bow would be a good choice instead of ruining an a perfectly good stave. We all know about sows ears and silk purses. That was my point.

Mo_coon-catcher:
With black locusts propensity to fret not long after it takes set (Atleast what I’ve worked) I would be afraid of the collapsed wood ripping apart when the set is pulled out between heat treat and sinew backing. I’ve had sinew rip apart wood that hadn’t been stressed past bracing. Now that was Eastern red cedar. If the limbs has any fretting I wouldn’t mess with sinew backing since I feel it’ll be a waste of sinew.

Otherwise I feel that sinew and black locust will be a good combo. Black locust has good compression resistance, forcing the sinew to stretch and work more. Especially once the black locust is heat treated.

Thanks guys. Last I heard he has decided to leave it as it. He realized after he did it he should have left it wider, but he’s the type that jumps in before doing any research lol. Sometimes he just gets ahead of himself.

bradsmith2010:
good points,,,maybe sinew backing without trying to heat it,, would have been a safer option,, and it may have shot ok,, but I have noticed that for a sinew bow to shoot very well I need some reflex,, that being said, best to him on his next bow,,,

Lots of good points i'd agree with here. Compressed stressed locust does not like to forced into tension, Have proved that more than once. I dont like thin ringed locust, it has seemed to crystal easier than thicker ringed stuff. That said maybe your friend has not narrowed the handle yet and could make it a bendy, good dimensions for that. But I suppose its too late for that.  Otherwise i'd agree with it not having enough mass for what is being asked of it. hope to get the finish on a new build soon, 1 3/4 out the fades and 65" ntn for a 27"draw. That is pushing the limits for me with locust handled bow.
