You can't just go blazing away on the screw driver otherwise you'll cook the heat treat right out of it. When I'm faced with this stuff I make the screw driver blade to where I have to tap it into the slot. You just don't cook the screw with a torch. Use one of the little butane "crack torches" and tap your screw driver insert into the screw to where it stands alone. It'll travel down into the screw and heat soak the immediate area without scorching the surrounding area.
We use this technique almost daily with the group buy as actions often arrive with base screws in less than pristine condition. The best bet is a tip out of the Brownells super set. The steel is better and you'll notice right away that the blade geometry on the inserts are radically different than what you'll find on a Snap On truck or Sears. I too have a pet affection for these optics and own several.īased on the work I've seen you post this probably falls into the easy category but than again it's the "easy" ones that destroy an excellent reputation. One thing I have heard is any heat on a Unertl is a no go but your method of using the screw driver tip as the heat sink is probably safe. Once the old goo is loose I can't imagine it takes much to break it free.
