You need to quit shooting in Death Valley! 118??!!??  

I agree it sure seems the main factor was the heat, add to that your DL. Have to believe that it would be much better for the bows not to mention the archer to shot in the morning or evening not the heat of the day...Wingnut builds high quality limbs, he knows what he's talking about.

OK I went back and re-read the thread. I'm outta' the glue camp and into the heat camp.

My guess is the heat.Really an unusuall canundrum.After reading wingnuts experiance,sounds like he knows.Ive never experianced much shooting in that kind of heat,but have in the high 90s with very high humidity with no problems.
Bjorn must shoot in some pretty hot times being down in Los Gatos,so its looking like the heat.

Do you shoot three under? After readying all the posts my money would be in the extreme heat in combination of the strain on the lower limb. My thoughts would be more strain on the lower limb causing it to break before the upper.

Do you shoot three under?

PS sorry to hear about that I'm sure it's a very painful experience.

You also must live to shoot after not quoting after the 1st two came apart.

Disregard the 3 fingers under comment.

Sorry for your loss

I vote extreem heat. Three bows within 20 min and none were built at the same time? 118 degrees? Tell us where you were so I'll know not to go there.

another vote for heat

I am curious, what color is the glass on these bows? Was it black or brown glass? Or were the limbs dark? I am asking because I have found that dark objects absorb a lot more heat.

The Bowyers Bench is visited by many knowlegable in the area of adhesives tolerance to heat. Just a thought even though many who have responded qualify as well. And I thought south MS. was hot!

I live in Sweetwater Tx. When I was a kid I can remember the temp on the bank at 128 degrees also yea I live to shoot. At first I did not even know what was going on all I could hear was a strange klicking coming from my bows. That evening I read a thread on TG about bows delamanating and the sound they made at the begining of a major crash, and if they were delamanating the glass would be foggy in the  spot that tey were coming apart. So I looked at mine and found everything you guys have talked about in the delam process. Rather then take a chance on having the explode on me I asked and listened to ya'lls ideas and thoughts on what was going on with these two bows.
Previous threads have proablly save me a great deal of pain and this thread has given me some real insight as to what happened to my recurves. Ia am in hopes that you will not stop giving me your insights on this thread and I hope you will continue to bing your thoughts into this.  
To those of you who I have not as yet answered personally I wish to covey my THANKS also and am still continuing to read them even now.   WITH THE GREATEST OF THANKS Ric

Cyred4d the glass is clear sir

Wingnut I have been shooting for a few years but have only started  real learning sence joining TG everything that I learned in the years before TG has been the hard way through books and hard knoks on my own.

Danny Rowan only long enough to pull six arrows the rest of.the time it was in my hands

Adamgti I shoot two finger split and thanks to other threads on what the begining of delamanation starts out like it was not painful to anything but my wallet

LongStick64 the 60" has two pins and on bolt and the 66" has one pin and one bolt

sounds strange  

Well it think the lesson learned here is that if it's 118 degrees outside . ..stay inside and have a glass of icewater.  Very hot conditions are very hard on bows.

atatarpm, were you hanging your bow on something? If all the limbs delaminated in the same spot then it might have been a hot pole or stone that that part of the limb was resting against. I had a friend have his ACS delam on him this past summer when he set it down on a rock in the sun to take a nap and it blew up right next to his head.

I'll vouch for Atatarpm..I also live at "Ground Zero"(Sweetwater,Tx).I didn't have a bow that delaminated(only a 28" draw)but I had two rolls of Fletch tape that died and an inside vinyl car door trim that let loose.Still haven't gotten that trim to restick with anything yet.
Hoping this summer is not a repeat.
Oh yea,I vote the heat !!
Come visit us Ric.
