The Bad With The Good

I have to admit it's been a while (no arrogance intended), but I made firewood today. I was tillering out a new warbow. Hickory back, yew core, ipe belly. 74" NTN. 1 1/4" wide at the center, 1 1/8" deep, tapering evenly to 1/2" nocks. I had it tillered to 125#@29". I only intended it to be tillered to 30", and I was looking for 120-130#. It had <1" of set.

I asked my wife to come and snap a few pics at full draw. I exercised it well, pulling it multiple times to 120#, no problems. To get a full draw pic, I had to hold it for 3-4 seconds to give my wife enough time to center the shot and let the camera focus. Catastrophic failure. After autopsy, I could see it blew a tip off. Top tip. I've been making my tips lighter over the years to improve cast and reduce handshock, but I definitely went too far and didn't leave enough meat on these.

Looking at the full draw, I can see the left limb (would have been bottom limb) is a bit stiff especially in the outer third. I would definitely have fixed this had it survived.

First pic: full brace
Second pic: 125#@29"
Third pic: my wife caught it just after it exploded. You can see flying chunks!
Rest of the pics: autopsy

Without the bitter, there is no sweet.

That sucks! Better on the tree than in your hands at a 120lbs. A lot of good action shots lately!

adb:
I wouldn't have to worry about it exploding in my hands! I can't fully draw 125# anyway. I can shoot 100# comfortably, but even 5-10# above that is impossible. The difference between 100# and 120# seems logarithmically different.

ravenbeak:
Wow,

I heard an explosion recently and thought they were blasting up the road,  now I know what it was!

Tough one,   I too am consistently playing the how small can tips be game.  I guess the rules get exagerated with draw weights that heavy.

All in all a good lesson in more more woops too much,

Easternarcher:
ADB, what were the dimensions of your tips? they look fine to me....but point of reference is not there.
