Resized the top pic twice andd it still looks too big. I took out that flat area out on the outer third on the right limb.

So far this bow seems pretty quick. I'm going to shoot it a lot more and check the tiller again.

I'd like to get it down to 50 at 28". It is amazing how little it takes with the scraper to effect a change on a limb.

Nice looking bow, Jim.  Is this the one you were working on in the summer?  Looks great.

I think it is the same on both sides. may be the shadow on the pegboard behind right limb.

Jim, I like that bow.  How thick are the limbs?  I want to make an osage bow and will probably use hickory backing.  My attempt at osage last summer didn't go well.  I'm using the pieces as accents.

Thank you. At mid limb they are about 1/2". Where you at in Ark? I get my osage boards near Salina Okla.

Well... this bow exploded at 28" Backing separated from the osage. Looks like a starved glue joint. Luckily it was on the tree.

Did you loose the backing and belly?

from the pic, it looked like a hinge starting about 1 ft (midlimb) from the handle on the right limb.

Is there where it broke?  Real sorry to hear it.  Its heart breaking.

Looks like the backing let go about mid limb. Not sure wich one was on the right when she blew. It was quite spectacular, i'll give her that. I didnt rough the to mating surfaces up very well. TBIII was the glue i used.

wow, I see what you mean by glue starved.  Did you use alot of clamps?  I am always afraid to over clamp.

sorry to hear about your bow. It's never fun, but they do make cool mini explosions.

 Wont do that again

That's too bad Jim. Looks to me that a grain run off where the fades were cut in is where the failure started.
  With TB glues you want smooth flat glue surfaces not grooved or roughed up.

isnt osage an oily wood?
Title: Re: HBO longbow
Post by: Pat B on December 21, 2010, 08:46:00 AM
Osage is oily but I've never had a glue failure with TB glues no matter what woods I have used. I do degrease with acetone but I know others that don't.

Sorry to see that. That must have sounded like a small bomb going off, bet you could tell your heart was still working just fine after that one.

Made several glass backed bows and was thinking about trying this style of bow but upon seeing this I think I will stay with the glass backing and leave this to the experts. Sorry about your bad luck and glad you weren't actually shooting the bow. Bows breaking at full draw is a scary thing with a broadhead at the end.

Started another bow of the same material.This one has one limb 1" longer than the other.

Have it to 5" of brace. Being optimistic, I glued bocote tip overlays, handle and a grip overlay.

I'm going to cut a shelf into this one and thought the grip overlay might help support it a little better.

Please Santa let me complete this one.
