Here's a copy of a pm a feller sent me with advice on how to fix it....
kris
it looks like you did a number on that bow!!but all is not lost--mask the glass w/masking tape--then get a decent clamp--c-type is probably best--then 2-pieces of stock--1/4-or-1/2"x2"x3"---enough to cover the damage and some of the undamaged limb--wrap the blocks w/saran wrap[so they don't stick to your bow!]
get every thing ready-then use thin super glue and saturate the damage letting it go in deepthem sqeeze it nice and tight[dont crush it--just good and tight]let it sit overnite--un clamp it--peel the masking tape-then carefully sand the core [edge]then put a drop of super glue on the damage and rub it in---sand again--when it looks good-rub some varnish in and let it cure--ive had this work more times than not--string it and let it set for a while--then try it slow pulling short draws at first then when your comfortable-come to full draw --listening for noises all the time--wear saftey glasses the first times your testing---this should work-it doesnt look too bad--good luck
I used super glue to fix mine and been shooting it everyday for for about two weeks or so, give or take a fewe days.
I used popsicle stick between the clamps and wax paper over them.
If it's not cracked to deep it can be fixed so don't freak out like I did... Just take a deep breath get your fixing stuff together and get after it. I used 180 sandpaper clean the damaged area glue it, sanded it, glued it, sanded it until it looked good and for the final I sanded it smooth and rubbed the heck out of it with steel wool #000. Put a little finish over it and WOW I was back in the saddle.
This weekend I skinned the bow with some canebrake rattler skins to cover the bad spot cause you could see it if you were really looking and it gave me a good excuse to skin it and it turned out great.
I'll post some pics of it when I get a chance.
Good luck and I'm sure some other's will give you some advice as well, Fine bunch of feller's here.
