I know that one of my books describes how to make your
own tubular lock
pick. I think its the one by Eddie The Wire. If anyone is interested,
let me know and I can provide more details.
What's to detail?
Make a cylinder the size of a key. Drill holes through it at the pin
positions. Put some rods through the holes, so that you can slowly and
carefully push one pin at a time while applying gentle turning torque, and
have the rod stay where you put it.
