Blind heat and delamination???

[David Mitchell]

A buddy had his RD longbow delaminate on him at full draw on an antelope.  We were hunting in Wyoming in pop-up blinds--temps were 95-99 outside the blinds--hotter than that inside.  Do you think the heat for two full days of hunting caused it?  Or was it ready to let go anyway?

There is a good possibility.Normally,I would think it would take a little more,like temperatures in a locked up car on those kinds of days.

How old is the bow? And how many layers of laminate and what is the laminate?

My guess is it is a combination of heat and possibly aged or poorly adhered laminations.

That being said, it gets pretty darn hot here in the summer, especially this summer, and I had bows in cars, out shooting 3D, sitting in direct sunlight while I shot other bows, etc... Luckily so far I have had no problems with the mid 70s Bear or anything made in between then and made more recently.

The bow is only about 5 years old--maple lams, black glass. Don't now for sure how many layers of lams--two I believe beside the glass.

Seems to me temps that would melt epoxy glue would kill a person long before the bow gave away.

Shouldn't be the cause in the blind.  Did the bow get unstrung when not in use?  Sounds like it was it's time for some reason.

We had one let go a couple weeks ago but a guy left it strung in the car for a few hours in 100+ heat.  Didn't do it any good.  I gave him a good deal on some new limbs.

It was not left strung when not in use, nor was it left in the truck strung. My suspicion is that it was going to happen anyway.

IMHO 99 degrees is not enough to de lam a bow  ............ maybe a bad glue joint is to blame  .......... I once laid up a recurve and used some old glue and it gave way the first time I strung it up
