I'll bet this has happened to someone else here:
I had a bow done, ready to ship to family member. It was hickory, 68", 27" draw. A fellow stopped in the shop and admired it so I braced it and handed it over. He pulled it back to ...hmmm.......30"-plus someplace and cracked it just north of the grip. Oh, crap.
I guess i'll start putting those "over draw" strings on my bows, and let the final owner take them off when they want.
Overdraft protection is a good thing.
(the crack is about an inch long, comes off the corner of the back and can be closed up with hand pressure. I may glue it, wrap it with artificial sinew and an over wrap of thin rawhide. It may shoot again, but I cant gift it this way. )
