Thank you! That's EXACTLY what I was looking for.
Here's the thread (from the keypicking forums) that explains the concept I'm interested in for bump keys (LINK)
. It could be that I just totally suck at bumping and gave up too easily the first time. But I had absolutely zero success at bumping any lock I own. I tried every imaginable variation of turning pressure and tapping force.
I know (as per your signature) how lame it is to blame your tools.
But I wonder if there's just too much slop in the bottom of each key bitting so that the force isn't being transferred well. The way this guy describes his bumpkey concept is that the barest of taps will immediately transfer force. Sooo, I wanted to give it a shot.
