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 was thinking also that the rubber rings looked like what my dad used to use for banding young calves. you might find some bands that would work on veterinary supply web sites under banding or in farm and ranch stores. I’m going to check tractor supply stores they should have something that will work.

  2. keyway is a 5R43? I know for sure it is not just one place you can get this one. I know 4 places in London you can get it and one being my shop xD

  3. Nice vid Bill but ….. its really grinding on me that you guys always always bump / pick the wrong the wrong way round ! its upside down Arrrrrrr, Never mind ill not let this spoil my day Lol – Great vid as always thanks

  4. It is a store bought (Brockage) that I got from SouthOrd.  When I lose it in the shop (often), any old plastic handled screwdriver works just fine.
