Just picked up a used bow and it has what appears to be 2 small linear cracks? in glass on belly side of bow up against string groove. Hoping to get advice on how to repair.
Pics:

Kinda tough to tell exactly whats going on there, those string grooves have definitely seen better days. Looks to be the glass is lifted on the left side, you could try whicking CA glue into those cracks and then clamping them with a small C clamp. Not sure there is much else that could be done.

Thanks buckeyebowhunter. Any recommendation for a wicking CA. I don't think Loctite make 452 anymore.

That's a start to a delamination. Don't shoot it that way.  Glue and clamp as suggested.  You might also consider adding another piece of glass, or glass cloth to reinforce the area.  A little epoxy and fiberglass cloth from the tip to about 1 1/2 inch below the nock would be about right.  You might pick up a scrap of fiberglass cloth from a boat/canoe repair shop if there's one in the area.  After filing and sanding off the hardened excess, be sure to sand the string string grooves so there's no rough or high spots.  Do the same thing to both limb tips, even the other doesn't show damage.  Good luck.

Order a bottle of starboard thin glue from Amazon. It's basically the consistency of water. Like Orion said you could try overlays on that side. A thin piece of glass roughed up, blue cap gorilla glue, and several c clamps or vice grip style clamps would hold it on. It's more work than it sounds like to do the overlays and clean everything up and then clean up grooves and refinish that area. If you decide to go the overlay route you can try what Orion said or I can send you a few pieces of scrap black glass.

Thank you all for the help and advice.

Just a thought, Could they the tips be cut off and the bow would be shorter by 2 inches and the weight could be made lower and the bow re-tillered.

Shortening the bow would increase the weight.

That's correct, but a weight reduction can be done to get back closer to original bow weight

That is really not a good idea to consider not knowing how much the original bowyer sanded the glass. You could easily ruin a perfectly good bow....

To the OP:

This stuff would be the ticket, but be real careful with it. Its excellent for wicking deep into a crack, but its just like water and can make a hell of a mess. Use masking tape on the edges so it doesn't run everywhere.   Then use an 1/8" chain saw file to smooth out the string grooves when you are done. Those are super fine files that are perfect sise for string notches. I typically use a little 220 grit to polish it up before sealing it.

Hope this is helpful     Kirk
