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. I’m sure you will be near JACK (Czeck) sooner or later, give them a visit and bring back some locks for the Tribe.

  2. From that look, cheap quality, however, the bow of key look like Schlage.

  3. Hey Bill. Good job on the disc detainers, I need to practice with those at some point. I have a question: I have with me a few master-keyable padlocks (Zeni Z16) and they were cut off and discarded where I found them (not mine, they were tossed away into the bushes next to a thing they secured; an identical padlock is present on the hasp); I disassembled them and they seemed to use 3 key pins pointing to the key in place of driver pins with a master wafer in between… I'm guessing that's why they were cut off, because if a slave key with all deeper cuts was used meaning those master wafers would be balancing on the point of the "driver" pin (actually key pin) and possibly rotated badly. This is present on two of these padlocks that got cut off. Both identical pinning. Why would theu use key pins like this? These pins flop around like crazy too. Some with tapered edges, some not. Due to their location and use, I would think they would be more professional than that.
