I recently purchased a cheap padlock from Harbor freight. It resembles a Master 220. I took the cylinder out to remove the pins to practice but I can't remove the core from the cylinder. It doesn't have a clip or any other retaining device on the back. I am stumped. How do I get it apart without destroying it. I will try to post a pic later.
btw, I have an american lock that I have done this to so I know what I "should" be doing.
