Pushed it Too Far
Damn, I should have known when to quit, 50# at 29" was plenty for a relatively short longbow.
But no... I'd shot a few at 30" and taken it back to 55# @ 30" on the tiller.
I'd taken some nice pics and was going for the full draw picture when it exploded on me.
I was a bit shaken, but rather annoyed with myself for getting cocky and pushing it too hard.
Still, better to explode on me than some one else.
Examining the break (lower limb), there is no obvious defect, the sapwood seems to have given way a few inches below the grip. There is a knot through the heartwood further up the break, but that doesn't look to be where it started.
It's a shame as it was looking rather handsome and seemed very fast, presumably because it was working so close to the limit.
As one of the guys on Primitive Archer says.
" If you ain't breakin em, you ain't makin em".
That upper limb (the Oregon one) is still Ok but having been messed about twice I think I'll give up on it. I might mount up the tips with their nocks as an illustration of horn nocks, I don't think I'll be able to take 'em off and re use them. maybe I could wear 'em as ear rings (joke).
Hmmm, not a happy bowyer, but onwards and upwards. I'd called it as an experimental bow, just a shame the guy at the club didn't get to try it, although he's avoided the whack on the head!
More Cheery Update:-
I've started on another stave which has had a year seasoning it was from Shaun at the club and hopefully there's a longbow in it.
See this post http://bowyersdiary.blogspot.co.uk/2012/01/yew-logs.html
I've run it through the bandsaw and it looks promising , it's a bit skinny but I've sawn off the excess sapwood, cut down the sides to approximate dimensions and cleaned up the belly to show the black centre pith of the log for a fair bit of the stave.
It's 84" long with a few knots, but with all that length I should probably be able to position the bow with the worst knots at the grip.
The stave has about 2" of deflex, I may add a little reflex over the last 1/3 of the limbs later, but we'll see how it comes along. I prefer to avoid the hastle of heat bending if possible.
The pic isn't very good but it gives an idea of the size of the roughed out stave.
