In repairing broken and cracked stocks,regardles of the adhesive, clamping is very difficult to do often times, and can damage the stock in the process.I have found that one of the best methods is to wrap a strip ,cut from an innertube,of rubber around the joint. Pull the "stretch" out as you go. A few wraps will pull the joint very tightly together, making Tite Bond II a good adhesive to use.This does not make dents in the wood and is easy to do.The Gun can be assembled to insure proper placment of the parts, without fear of gluing the stock to the gun(with Tite Bond II,not epoxy).
