with cracks, i make sure their is no oil in them, just bare wood. then i drill a hole in the middle of them if the crack is hidden. small hole. then i keep putting super liquid glue in the crack via the little hole in the middle. let it dry for a day or so. never had one come apart after that. if the crack is where you can see it on the stock, make sure that area is stained the way you want it as you cannot stain super glued wood. you can stain it before you glue it though. open the crack some with pressure and put in thin liquid super glue. release and let dry. it will stay together. if the crack is the opposite side of the lock on the stock. i glue and pin from the top with a stainless steel sheet metal screw. first glue the crack. then from the top drill a very small hole down through the crack. take a non tappered sheet metal screw and put some super glue on the threads and screw it into the hole flush. that crack will never ever move again. cracks dont bother me. i was given a savage barn 22 gun with the stock in pieces. when i was done with it it was a very good gun to shoot and to look at. my son uses it on his trap line to finish the coons he catches frequently. their are so many frozen coon on the deck that ive stopped counting them. cracks are nothing, just fix them. beech almost never cracks, maple rarely, walnut is prone to it, never make a gun stock out of even a beautiful piece of oak. oak will start coming apart with the first shot you fire.cherry lasts forever and never ever warps.
