I'm starting to think about restoring a 1863 springfield rifle that was nailed to a board and slathered with polyurethane. The worst part was someone tried to de-mill it by hitting the barrel about 2'' from the muzzle with an ax. Im looking for suggestions on the following; *What method and what to use to strip the poly off. *What's the best finish to use once I get it down to bare wood. *I intend to cut the barrel and re-crown it, any alternate suggestions? *I do intend to shoot it once I restore it, or at least make some noise and smoke. This will be pending inspection of the condition of the barrel. * Does anyone know what method is used to attach the original front site to the barrel? I'm probably going to silver solder a new site on to the barrel.
