Two top line recurves both left handed first a 66" 63#   lower limb on the right side about 6 inches from the riser. The other bow is a 60" 63# and a 53# set of limbs built one year apart from each other. All three delam's happened at the same time within hours of each other. What I am looking to find out is what I could have done in my form to make this happen?

OK is this a box store bow or custom from a bowyer?

Both bows are top line costom hand built bows.

I will not name the bows because I do not believe the bows or the men who built them to be at falt but you can find then both in Trad Bowhunter Mag. every issue.

Hmmm without know the particular I'd would give the fella a call and discus the issue to come up with a resolution. I think that about all you could do?

Gota remember...sh*t happens...does it suck sure but these bow are made by hand and there are alot of variablez to consider.

The thing that gets me is that I have to believe it was or is something in my form. None of my long bows have done this only those two recurves and I don't want to buy another recurve untill I have a idea about what happened.

Arrow weight to low possibly.

Light Arrows?

It sounds like maybe something to do with atmospheric conditions, exceptionally
dry, wet,heat, cold?  just a guess but if they happened within hours sound like something to do with that time period?

The arrows  weight was 680 grains.  Not being mean here guys but all three lower limbs delambed at exactly the same place within hours of each other. I am a lefty and they delambed on the right side lower at 5.5 inches from the riser two limbs were made by one bowyer in Tx a year apart from each other. While the other was made by a bowyer in Wa. three years before that. Really am looking for help here. Would string torque have any bearing on this?

Storage, exposure to high heat, dry conditions. Left strung during long periods?

Is your draw length within the recommended range for those bows?

Hummer3T that is something I have not considered it was 118 degrees out that day.

Owlbait both bows were extremly well treated and cared for.              Looper I have a 31.5 inch draw and the Tx bowyer said his 60" would handle that, but I hace very much wondered about that, and the other bow is a 66" I would hope it could handle my draw

I bet the heat is the primary cause. Are these takedown bows or one piece?

Looper they where take downs sir

I have to agree that heat probably is the culprit. Are they stored near a vent or hot water pipe?

I just don't think anything in your shooting could do that.I think it would have to be related to the heat.

118 degrees in February? Maybe the heat/cold temperature switch paired with the extreme heat? Were they black-limbs? Those are worse in the sun.

I am thinking something simpler..like a bad batch on glue? Maybe not curing properly?
