One of the most aggravating things a gunsmith/blacksmith runs in to is when the owner of a rifle puts his scope bases on with thread locker and the gunsmith can't get them out. I broke 2 torx bits this morning trying to do just that. I even heated one with a soldering gun for several minutes with no luck.
Some gun owners must think the screws are holding the drive wheels of Kenworth together.
Ya think....
