Osage 5curve with a concave back 49#/28” (No. 97) – Stonehill Primitive Bows

Osage 5curve with a concave back 49#/28” (No. 97)

This bow is made out of a unique stave. The back is along almost the entire length homogenous concave. This is enormous mass saving, but tillering is a bit more complicated.

The belly ridge comes out of the fades and ends with the tips. Cross section is more or less a 5edge with a concave base (back) and tapers at the last inches into a V-shape.

The bow is very light by mass and I think it would be a good candidate for flight shooting too. I’m curious about the calculation with Steve’s mass theory.

One minor crack at one side of the upper limb (probably a wind check) was filled with thin super glue – no problem.

The bow seems to be stiff handled, but it isn’t. There is a very little gentle bending in the handle and the built up is therefore done with three layers of sole leather. Another piece of leather glued onto the back made the handle deep enough for a comfort grip.

The handle is wrapped with black leather lacing and linen yarn.

Black buffalo tip overlays.

The back is darkened with osage soup for a two tone appearance.

I like this bow very much and hope the new owner also.

Wow Simon that is an amazing bow! Was the back already concave or did you shape it like that? Been doing some flightshooting lately and woul love to try that one;-)
Cheers,

    Thanks Leon,
    it is the natural back of this stave. Probably the 1 under 1000 …

    Nice to have you here checking out my site.

Wow that is a rare stave for sure! Looks crazy but in a very good way! Been missing you on PA so check your site now and then to see if there’s some new bows;-)

Hi Simon,

That is a fantastic looking bow, I am very intrigued by it! Did you present it on PA as well? I find the geometry you have come up with really great and what a light weight bow it is as with that draw weight! How did you recurve it, with dry heat and oil? Did you add the belly ridge after recurving it? I have seen this type of wood with a concave back on maple trees in my bush where two trees grow very closely together and the one wraps itself almost around the other. Since they are no good for lumber, I should try to cut some of them and try the same thing. Do you think this would work with maple as well?

    Thank you Philipp,
    the recurves are steamed in and the ridges are carved after steaming. And maple is good bow wood, try it! At least I would do so.

Thanks for the clarification Simon, you have me inspired now to try a maple bow with a naturally concave back.
