Title: Backwards Osage.
Post by: Pappy on March 10, 2010, 06:55:21 am
Question ,Gary Davis stopped by yesterday on his way to Texas,he had told me he had something different he wanted us to work on on his way back next week.He had 2 Osage stave's for a small
diameter Osage tree.They have the ring chased and 3 layers of sinew on them. The difference is the back is the belly,He chased the belly side.The one he gave me still has the bark on the side facing me on the handle,My question is has any of you guys done this before,I have heard of reverse bows just can't say I ever seen one or how they may act different for any other.Wished I had taken some pictures,I will get some up later. :)

Pappy, Tim Flood used to make backwards bows from hickory at Mojam.  As I recall, he tillered the back of the bow. They worked out well and shot great.  I've never built one, so can't really help you much.I could see no difference in performance. I always figured it was just something different to make?  ;)

looking forward to the pics

Should be a interesting project. I'll have to watch you two pro's work through it. :)

If you think about it in terms of how ACS works, there could be something too it.  Theres bound to be a smidge of concave, or at least flatness to the back, and I've always held the notion osage rings behave as laminates under strain.  I'd imagine with care and the right specimen the back ring could be made sound enough, particularly with sinew and in light of Timo's recent experience using quarter or rift sawn osage as a backing.  There was a time I would have predicted the back ring would fail, but this could be an interesting project.  But the effect, or advantage, may not be so pronounced as to be revealed in a typical design and/or crafting.

Tim Baker has said that wood doesn't know which way it's supposed to bend........

I've made some Ipe self and backed longbows with the wood in all angles. I don't think it matters too much as long as the fibers follow the back. The last laminated bow I posted here was  composed from two of Timo's edge grained slats glued together.  I bet historically it happened more than we would have thought would have.

Gary lives a few miles from me and buys quite a bit of osage from me. Those small suckers are his favorite for pony bows. He just called about a week and a half ago and told me he wants some about 4 inch diameter for a project hes working on.

It seems to me that by making the bow backwards, the high crown of the tree is not an issue as the back. Should turn out fine. Good luck.  ;D

I agree with ryoon.  Especialyif the back is chased to one ring, the bow doesnt now its backwards. I bet it works out fine.
