(871) Ted Park’s Master Challenge


LockLab is Fan funded!  Help pay for stuff to review, break and talk trash about, and maybe even give away when we’re done.  Join the Tribe!

My vises are made by Panavise, a U.S. Company.  The one with the wide jaws is the model 350.  The smaller one is the model 301. Both have the 312 Base mount – www.panavise.com



  1. That “T” driver pin in chamber two: I bet the narrow top portion was at the shear line because of the key pin being so short. I bet it would have felt like a spool with strangely varying tension as the spring wiggled about on the narrow top. Just my opinion, but I wouldn’t discount it too quickly.

  2. Hey Bill, if I accidentally signed up for one of the giveaways twice, would it automatically erase one entry? I can't remember if I signed up for Wednesday, and I don't want to cheat or be disqualified. Thanks.

  3. Hi Bill, I'm a new subscriber and newbie at picking. I wanted to ask if you have any advice on lock identification. I have some practice locks which I can pick easily but I'm having problems with real locks. Thanks in advance, keep up the good work
