Might try a very thin CA glue and let it run down in between all the cracks then clamp together. Carve you some new limb tip overlays for the back and belly side as close as you can get to a perfect fit, then Gel CA into place and clamp. Sand and file string grooves using the old ones as a guide. Then finish over all with the thin CA again. This might hold up for enough shooting to get your buddy interested enough to make a small investment in a bow in huntable condition. Pad those loops and use a B-50 string might help to last a few shots longer. Two bottles of CA (1thin/1gel), sand paper, string file,clamp,new string,50-60 bucks or so. When it wont shoot hang'er on the wall!! Like Dano said might wanna invest that money in a shooter if you dont want to invest the time and GAS in hustling up the supplies. Best of luck, -Greg
