I have large screwdriver I use for through stock bolts. When I remove a screw I usually find some sort of bushing that will fit the stock hole and put it over the driver bit about an inch from the end. Rubber faucet washers work well. In a pinch you can wrap the shank with tape until it fits the hole. This keeps from letting the blade get off center, wedged between the screw and stock and breaking the stock when you "reef" on it.

Thanks for that word Chuck, new one for my gunsmithing dictionary.

My problem lies in reconciling my gross habits with my net income.
