I would never tell someone to do something unsafe!
But would never say it can't be done either!
I, personally would try, after, you contact the manu. and exhaust that avenue, first!
I personally fixed an ol shakespear Necedah, that had a severe twist. It was given to me by a coworker, free, he knew I loved ole bows.
After a slow process to return the limb to norm, and alot of shooting by my son, it developed a longitudal crack in the glass, in that limb.
I put super glue in the crack and then wrapped the limb and then left bow strung. Flexed the limbs every now and then until I felt it was ready to shoot. It held and my son shot his first archery deer with this bow, that October.
Wish I could say the bow is still a shooter, but my son left it at a friends house one weekend, and their house burned down, following. Lost a new pair of coveralls, too. Thankfull, no one was hurt!
As John says, if you do the repair, work the limb on a tillering tree. But the real "Show" will come after shooting! Flexing alone, will not show what the limb will handle under the stress of a completed shot!
Wrap the limb, in case, to enclose a collapse, if failure happens. I used a camo cloth type duct tape. Let us know your outcome, please.
