To me, it looks like one of the little cracks that can pop up when you bend in some reflex with a heatgun. It happens in tension rather than compression because the wood is being bent backwards. They look similar to frets but they are horizontal like that instead of diagonal like frets tend to be. Is that a possibility? I worry about those less because they weren't created by too much compression, and they are usually in places that aren't under a lot of stress (the outer thirds).

That's what I see to Weylin but I might not be seeing the frets.

Ill try to get a better pic or two...

Dry fire as in release w no arrow?  I’m sure I’ve had a botched release or two where the arrow for one reason or another didn’t stay on the string and didn’t leave the bow....damp fire? Never on purpose released the string was no arrow on it.

Is it a problem? Just something to keep an eye on?

Thanks so much everyone!

Sure looks like a chrysal to me, even though a very minor one. If that is actually on the belly, I just don't like the way the belly is rounded so much. I would flatten the belly of the whole bow and thereby scraping off the chrysal and see how much draw weight would be lost. If not too much, you would be better off that way.

I’m with Weylin on this. Did you induce reflex in that area or not? On mine I finally seen it in tiller and left that area a bit bigger. Arvin

He said it is 16 years old. I doubt he was heat treating it into reflex! It does look like it could be a tension failure induced that way though.
If you show us it at full draw with a mark on the spot where the chrysal is it should be obvious. You can also string it and see if it fells raised. Or rub it with cotton wool.

The heat treating revival began in the summer of 2002.

Show us the strung bow profile, it the tillering is a little off this could be the cause.

They don't get any better and they only stay the same if you don't shoot the bow.
The eventual ( hard to predict the time line) result is that the bow will fold up like a book.
I have had that happen on a bow I made for my younger brother of blessed memory.
I saw it happen.
I already mentioned how to handle them.

I did not start building bows until 2004 . But I was putting heat on them then . All wrong for the most part. But I did not have you guys to tell me I was wrong because that was my pre primitive archer days and my computer days.  Arvin

Some better pics....

Here are some more pics...area of concern is about 6 or maybe 7 inches from tip.  The tip with the string loop, not the end with string tied to bow tip.

thanks so much for your input.

Not likely that they are chrysals as the limb doesn't seem to bend in the outer limbs anyway

Not a chrysal, more likely a tension crack from a tip correction. Or it suffered car door impact... Either way, ignore it and enjoy the bow.

They either came from the semi dry fire you spoke of, or, when the limbs were heat straightened at build. Odds are the wood just had to become much darker for you to see them. I wouldn't even think about them and continue shooting your bow. My favorite bow has them on one end and has been shot a zillion times.
