48" osage bendy bow ?
« on: February 09, 2013, 10:12:55 pm »
I'm working on my first bendy.
It's 1" wide @ center to 3/4" at tips. 3/4" thick @ center tapering out. This is a sliver I had laying around.
Also it has or had about 6" of reflex.
It is flexing at center but I'm going to stay away from it for now.
I have it at short string now and know it will be light but that's OK, this is practice.

My question. What kind of draw length can I get from it?

Never mind. Pulled about 15" and broke.
Learned a few things anyway.
Thanks

Any clues as to why it broke? It should have made it farther than 15" unless it was way too heavy poundage.

48" long and 1" wide.  That is a tough design to pull off.  And for me, I know sometimes those slivers of wood that get thrown into experimental duty don't always get the same kind of back treatment as less-experimental staves.

I think is with that much reflex along with being narrow and I was doing some what of a rounded belly.
It may have been ok if I had more length or less reflex.
It was looking good for awhile.  ;D

Don where did it break? That length and width would have made a nice little D/R bow. Just something to think about for a second try.

Broke at mid limb. Just got done getting the handle to bend just a bit more to.
Thanks Jon I will. This one could have been done that way. I had to do a lot of straightening anyway.

Those 6" of reflex will probably have to be added to draw lenght to get an idea of the stress in the wood. So about 21" when it broke. I never touched osage, but with other woods, a flawless stave and tiller might have allowed only little more, 2"or 3" maybe.

The shortest I have gone is 50 inches, 38 lbs@24. 1 1/8 inches wide.  It can be done.
I should add, it had 4 inches of natural deflex. I tried to make one from the reflexed sister to it and it broke. You need deflex on this style bow. IMHO

Add 2-3 layers of sinew and hide glue and it will bend much farther than half its length, and a bunch of reflex will come right back. Try again Don!

Reflex doesnt break short bows, poor tillering and asking too much from it does though, IMHO.

Chris I agree and disagree. Sinew and reflex is good because of the shift in the neutral plane. Too much reflex on too short of a piece of wood will USUALLY add too much stress.

Im finishing up a 46" ntn bow that started at 6" of reflex, it pulls 26", but feels better at 25". I will let you know how it goes. Here it is tillered and shot about 15-20 times.

It just depends on the particular piece of wood...I've made enough highly reflexed to start bows unbacked and backed with sinew or rawhide(n had all 3 types break)...and it takes an exceptional piece to survive because it is asking a lot of the wood.....its like gambling...you just might go broke

Chris are you counting the approximately four inches or so of flipped tips as reflex or six plus the flipped tips?
