As an amateur, novice, hobbyist "gunsmith" who haas buggered a few screws in the past despite filing tips to match slots and being careful, perhaps I need some pointers on technique. Any web-based tutorials?
Do real gunsmiths use a brace on all sorts of screws? I saw a photo in the archives of CrossedChisels using a brace when removing a hinge pin. Looked like a special case.
On my present project, I've been stymied by a very small screw that holds the cam that retracts the locking lugs. Tried penetrating oil, heat, and vibration and finally gave up after minor buggering.
