So I'm working on a medeco cylinder that came out of a 833C S&G. I started with one pin and the sidebar to get a feeling of what it feels like for that side bar to engage under tension. I am picking the lock counterclockwise. After opening the cylinder a 1000 times I added one more pin. Picked it open again until I felt comfortable. Now once I added a third pin I can't seem to pick it open. I did not use any mushroom pins yet because I wanted to get comfortable with the sidbar.
Any helpful tips???
I know I just have to keep at it and it will open but it's really beating me up.
