I need a good 6 shooter one day..Had a 44 given to me but had way to much rust since the previous owner didn't take care of it..So it was pretty much scrap metal..
sometimes rust can be taken care of. My cousin bought a blued Ruger Mark I semi-auto .22 awhile back that had been left in a pistol case and really rusted to the point that there were some deep pits. The bore seemed to be ok though. He gave $50 for it and brought it out to the house to see what we could do. He was in agreement that if we ruined it, there wasn't a lot of money in it, so lets just see what happens.
We took it apart, and on any flat spots we put some 200 grit sandpaper on a table, and worked it back and forth until 90% of the pits disappeared. The round barrel assembly that separates from the lower trigger and grip assembly was going to be a challenge because of the taper in the barrel, and the shoulders where the barrel and reciever come together. I have a 6" grinder at home so we bought one of those cloth buffing wheels, and some rubbing compound, just like you get to buff your paint at the auto store. We just hand buffed it back to smooth in pretty short order. Then we put another clean buffing wheel on the grinder, and put "semichrome" polish on it. You can get it at most motorcycle shops for polishing chrome. Its a very light abrasive, so we polished everything back to a mirror finish. When we got done it looked like a chrome plated pistol
By this time the "hot blue" kit we ordered from Brownells arrived, so, following instructions we put the parts to be blued in the over and brough the temp up as instructed, took it out, rubbed the blue into it, and put it back in the oven to cool slowly. Once we reassembled the pistol it actually looked pretty good. If you held it up to the light and looked down the side you could kind of see a couple of slight wavy areas where we really had to buff a lot, but over all it took a junker and made it back to a shooter for less than $40 ;D
