Manipulating safe locks can be fun
and profitable! It also takes practice. I recently bought a used safe combination dial lock and mounted it to a piece of reclaimed wood. Mounting a dial lock involves threading the dial spline bolt through the combination wheels, and then hammering a soft, brass "spline key" into the spline's notch so that the dial will turn the wheels.
My lock came without a spline key, so I searched around the house for some brass to use. I found a spent bullet cartridge casing, and attacked it with a rotary tool cutoff wheel to get a sliver of brass.
After sanding off the rough edges, I folded it over to the proper thickness to fit snugly in the threaded spline.
One solid blow with a deadblow hammer, and the soft brass wedged in place. The dial now turns beautifully.
I'll be bringing this and some other cutaway locks to Boing Boing's Weekend of Wonder, where I'll be teaching lock picking workshops, so if you're attending, please come check it out.
Last chance to join us at our 3-day extravaganza this weekend in Southern California!
