5 Piece yew bow
« on: August 29, 2017, 09:38:59 pm »
I've been shooting this yew bow quite a bit, just trying to get the final tiller dialed in. it was 53" NtN, 55 lbs @ 26". it had a nice kink at a knot in the upper limb, or in these photos, the lower limb,with what looked like a section of rot on the belly side which looked really neat.
I use my phone to take full draw pics, it takes 10 rapid photos. I thought I would shoot it upside down to see how it looked when flipped. Just a recommendation, not a good idea once you have reached full draw on such a short bow. I reached full draw as the camera starting taking pictures, and this one piece of yew, turned to 5. All I could do was smile and laugh. The limbs gave out in everywhere. I can't tell where the break initiated, but it broke at the knot and at the thickest part of the fades.

Bottom limb failed first. Probably at the knot. There is a ghost image at the tip of the lower limb as tge broken limb came around.

Damn! Hate to see that.  Only bow that has ever broke under my own draw was a Yew bow.  Hoping it was a fluke.  Osage always let me know earlier if it was gonna fail.  The only Osage that exploded under draw was on the tiller tree...and it made a distintive cracking sound before hand...it was laminar cracks just like Ryan Gill warned about.  And a 2 Piece t/d at that... :-[

Really hoping my next 2 yew bows turn out...

To bad it was looking good, that was asking a lot from a 53 inch piece of wood.

At least you got pictures of it happening in real time, that never happens!

I am sorry for your loss though.

All of the above.
That knot is bending way too much.
Knots should be tillered to appear slightly stiffer than the rest of the limb.

That bow was too short for the draw length and the condition of the stave with knots, etc.

If the bowyer gets one or 2 full draw explosions he/she learns to fit the design to the stave and not vice versa.

I've had 5 (that I can recall) full draw, full fledged, while I was shooting, explosions... 2 or 3 of which drew blood so I learned that lesson quickly.

240m3srt, yes, from my experience, yew has never given me any warning at all. it just goes when it decides it's done.

Pappy and George, oh ya, I was asking a lot of this thing, but its fun to try. Besides my pushing the limits, flipping it, and trying to shoot upside down wasn't the smartest either.
The knot wasn't bending too much, its a kink in the stave, and that area was left thicker. I would have posted a unbraced profile.......but.
