[QUOTE="Garycrow, post: 900576, member: 30743"] Torqueing the action screws during bedding is a very bad idea. The point of bedding is to allow the action to lay in the stock stress free. You're trying to make the stock fit the action not the action fit the stock. If you torque the action screws while the epoxy is unhardened then you're just bending the action until it tightens down against something hard, which is whatever solid piece of the stock that it happens to touch. You now have a slightly bent and stressed action that's going to go back to that same bent and stressed state when the epoxy is hardened and you've cleaned up and reinstalled it. In essence you will have accomplished nothing with your bedding. The goal isn't just to achieve tight bedding, it's more to allow the action to rest in the stock in a consistent place and stress free. Tight bedding and a stressed action = bad, Tight bedding and a stress free action = good. The right way to do it is to use the bedding screws with no heads sold by midway or brownells, or do like I did and bought a couple of long hardware store bolts and cut the heads off them. I then wrapped them with electrical tape to give the needed clearance. When you put the action in the unhardened epoxy wrap it snugly with surgical tubing or if you're cheap like me wrap it with a bunch of wraps of electrical tape. The goal is to hold the action securely in place without putting any stress on it, surgical tubing or electrical tape won't generate enough force to induce stress in the action or stock but it will hold it securely in place while the epoxy hardens around the action. The epoxy will fill all the voids if you did it right (and even if it's kind of ugly it usually works just fine). Set it aside and let it harden for a day or two before popping it out of the stock. When you pop it out you'll have a negative imprint of your action and your action will go right back into place. You can then torque it down to spec and there won't be any stress points, the force will be applied evenly across the action to the stock which is laying in it's perfect bed. Avoid the urge to put a headed screw in there and tighten it down when the epoxy is hardening, by doing that you're totally defeating the purpose of bedding it. DON'T DO IT!!! [/QUOTE]
