I made Mississippi Dave a BBO that had a lot of grain islands on the belly. They started popping up just like your crack for no apparent reason.  I had him draw the bow to open the cracks, filled them with super glue and gave them a super glue soaked thread wrap like this. The bow is holding up just fine.

Wrap it with silk thread and TBIII. It will be fine. It appears you may have tried to bend it to soon. Those swirl areas are REAL buggers to flex outward like that.

This is on the belly of the bow? If so, there is a picture in one of the BB of cutting out a chunk and gluing in a block replacement.
Bowmakers are a little bent, but knappers are just plain flaky.

I'm with Bevin. The block is called a Dutchman, perhaps because of the practical ingenuity attributed to the makers of windmill-land drainage.

It's not really a dutchman but similar. When using this method you need to be SUPER accurate. Both pieces MUST mate perfectly. If it's too tight then you will have problems -too loose and you'll have problems. It's possible to repair bows perfectly well like this just go slow and be very careful.
Wrapping isn't going to fix anything in my opion. Simply hide it a little and maybe stop a few splinters flying if it were to go bang.
Did this happen when you reflexed it while heat treating? If so next time make sure there is less bend on these island areas while reflexing by using shims/clamps. Islands are just waiting to pop out when under tension.

I pretty much agree with Mike, :(I would probably wrap and give it a try,it really depends on how deep it went ,with humps with knot/swirls in them it is very easy for that to happen,I finely learned not to give it that one last crank of the c clamp and shim it keep the pressure off that spot.Good luck,keep us updated. :)

Those plug repairs are a real PAIN to pull off. I gave up on them. As mentioned the fit has to be perfect for it to work. Your issue isnt that bad and my feeling are your risking a good bow that could be easily repaired with a wrap Soybean.
