Tension fracture on my bow?

[bownarra]

For future reference what you should've done is left another 1/4" or so extra width at that spot. Or an 1/8" to 3/16ths either side of the limb. Water around a rock in a stream Then you wouldn't have a problem.
If you have a knot the wood around it is different to the clean wood and not able to take what the clean wood can. If you 'add' the extra width around these knots they aren't a problem because you have compenstated for the lack of elasticity around the knot.

I think we need some circles and arrows. I can see what I think is a splinter to the lower left of the knot. It looks like it's outlined in grey and is about an inch long. Looks like it turns into a longitudinal crack.

   yes not quite sure what Im looking at,,
anymore, if I have a bad spot on a bow,, that looks like trouble, I sinew wrap it after I tiller, just to get ahead of it before it gonna cause a problem,,if I think its really bad I sinew wrap and tiller through the sinew,, then re wrap when done,,,
   I dont mind the way it looks,,and a sinew wrap or rawhide back will not hurt anything at all,, I know some dont like either, I love both,, they give me peace of mind, even Jay Massey said, I dont trust an unbacked bow,,  I have unbacked bows Ive shot for 20 years so I do trust them, just not if they have a bad spot,,

A wrap of some kind of twine set in glue and a sinew wrap set in hide glue might also help.

Let me offer some observations on how to avoid this problem with knots.

First, leave some wood around the knot. Let the grain limes swirl.

Second, the  tillering leave knotted areas just a little stiffer than the rest of the limb.

Knots, are prevalent in staves and learning how to handle them is important.

yeah i definitally need to get waaaayyyy better at it. I layed out a bow on a stave and once i roughed it out to a 1.75" all the way down the bow and 1" thick, i realized that this was not going to work.... i have a habit of getting the easy things wrong and the hard things done way better than i should.

That's an ellipse! I wanted circles or arrows!! Joke I don't know if I'd pay that any mind at all but I don't have a lot of experience with cracks. I've been lucky, they either break or don't. That is so small. I'll have to defer to the other guys.

Real nice ellipse, though !  I think a sinew or rawhide wrap would hold it together, and also preserve the character.  The other folks have more experience with those things than I do.

I think sinew or most other natural fibers would fix that .... I had a big crack similarly looking to the one you have there show up on my favorite BL bow and I just took some dogsbane soaked it in glue and wrapped the whole knot real tight... still holding up after a few hundred shots

Ok I see it in the ellipse now. Not sure what to think. Does look like it could be a fracture. I don’t remember that knot Russell. It’s been awhile. Where is it located on the limb?

here ya go, the back side is facing down but heres a approximate area


and heres a before picture
