If you dont't make them you don't brake them :)
Even small pins and knots can ruin the nicest laminate. Indeeed the strongest argument against edge grained laminates. As mentioned a patch will save that bow in case its getting worse Kidder...
Not sure if I can patch this one tough....
This one was ready tillered and pulled to 110# @ 33" a few times. I called it good, made and polished the nocks and tought I could get rid of the very small amount of set (and maybe gain a few more pounds) with a gentle heat treating. DON'T DO THAT ON HEAVY YEW WARBOWS! It was a perfect stave, very good and careful build and tiller imho....goodbye @ 108# @ 31"...

M2A:
Fall of 2019 I was working on a piece of American beech. Target weight was 50 lbs at 27". Had it tillered out to 26 or 27"(been a while), but had put a few arrows through it and it was real close to shooting in. Bottom limb was starting to take on a little string follow, 1/4" or so. I could not notice any thing wrong with the tiller and it shot good, but figured the top limb needed a few scrapes to even things out. but it was almost ready to start to shoot in.

Ya I’ve had failures. Even exploding ones. Here’s a good example of a few rookie mistakes. This was from a couple years ago with a yew wood recurve bow. The stave was decent but had some dog leg bend and twist in it one one end. I was able to heat bend them out for the most part with oil and dry heat. I believe I over did it though and made the bow too brittle. Also to blame it the bad tiller choice on this one. I decided to go for a more elliptical shape for my tiller and didn’t do a very good job with it and the top limb was stressed too much in the outer 1/3. The bottom not as bad but stressed as well. I learned from this bow and remembered to only heat correct an area once and only as much as needed and not ask too much of the wood. The tiller choice was not wise either on this and so I found out that the combination of the two errors caused an explosion of the bow. It was like a gun went off actually.

Looks like about a 9.9 on the pucker factor Dave.

Yup it was! Just lucky that it didn’t come back and hit me in the face and take my eye out.
