Hi:
Shimming is nice but I would like to make a more durable one.
Where in this site can I read about this? I would thank you a link, please.
Instead of shimming i've been able to open some cheap locks FERMAN trademark (combination locks, at least I call them like that) by feeling the correct numbers. For example: 3, 25, 10.
Where may I learn about the inside mechanics of this locks?
