im not saying that broke it,, but something to consider,, but bows are more likely to fail when moisture content too low,, It might not re hydrate in low moisture condidtions,, I have a moisture meter and my bows were getting below 8 %,, so i sprayed the bow I was working on to get it up to 10,,% cause I have broken bows and then measured them and they were 6%,, I asked Mark ST Lous about heat treating a bow in low moisture climate,,, and he said dont on that particular bow,,,, so I am just careful and take it into considreation,,
Im just saying maybe you didnt do anything wrong the moisture content got you,,
