Imminent belly failure
« on: November 23, 2014, 05:36:30 pm »
Working a bamboo/purpleheart/osage/walnut composite. I needed to leave more belly and or length, if it'll be walnut.

Oh, and if this was about my personal anatomy, the belly failure already occurred. :)

Oh well lesson learned move on to another one.  The bow looks short and to heavy to make an even bend.

The limbs look pretty thick to bend much. Perhaps, you forced it. Jawge

Maybe it's not as thick as it looks. It was pulling 40# at 20" when I noticed fatal flaws.

If you try it again, use the osage for the belly and walnut for the core.  Osage is much stronger and way more elastic.

You've got to be gentle, gentle when using walnut for a belly. It's very soft and not very dense the best backing for it is ash imo.

Lots going wrong there...put the walnut in the core n osage on the belly...IF you just have to have walnut as a belly use maple,ash etc(one of the lesser overpowering Whitewood's for backing),and then you have to go longer and much much wider than what you have....trying to use walnut as a belly in lam bows is a waste of time n materials IMO....I'd grind off the walnut n glue on some osage to save that if that's what ya wanna do

  Walnt belly, bamboo back and a thick cross section is asking a lot of walnut.  The only good walnut bows I have made were hickory backed or self bows and 2.25" wide or so.

   That's a shame, looks like a lot of work went into that.  I get upset if I take too much off of a self-bow stave and it lowers the draw weight.

   I couldn't imagine the work that went into cleaning up those ply's and glue-up.   Maybe you could salvage the handle and glue it in-between some full-length boards/plys......  bamboo flooring?
