A plug spinner is the obvious choice, but if you don't have one it is tough. You can substitute a spinner for your tension wrench, and a rubber band. Turn the plug nearly back to home, and put the wrench all the way into the keyway on the bottom. Then slam that wrench with a rubber band(or anything really) so the wrench turns the cylinder to the other side. Not the best solution, but it works.
Wow! It works like a charm.
I was searching for good plug spinners. Now that I know the trick with the rubber band, I'm starting to think that I don't need a plug spinner

After that encounter I sat down and learned to pick high quality, tight tolerance cylinder with a rake or a diamond pick.
I noticed that a lot of people use a rake or a diamond pick to pick the lock. I know the principles of raking, but never use it, because for me it seems like it's faster if I just use a standard hook pick. I probably need to work more on the raking technique.
I've never used diamond picks. I read that diamond picks are used if you need to apply more force on the pin to push it. Is that so or can it be also used like a standard hook pick?
