I'm not sure I'm posting in the right subforum, but I hope I am!
I need help removing a retaining ring from a lock cylinder that I removed from a doorknob lock. I want to disassemble the lock completely and re-pin it for picking practice, but I can't seem to be able to get this retaining ring off without a retaining ring removal tool. Any tips on how to get it off without damaging it too much so that the lock can be reassembled?
Here is a picture of the cylinder. You can see the retaining ring pretty clearly: http://i.imgur.com/KI8jmIk.jpg
