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 thinking that weird pin might be an anti-bumping device. The narrow shaft goes up inside the spring and its length is set to stop its upward movement right at the shear line. Sure a bump would still move it up but it wouldn't be at the shear line long before bouncing back down. Combined with a spool or two, should be hard to bump.

    I don't know, I'm probably totally wrong but I can't think of anything else. 

  2. I heard you say that the ball bearings on the side are for key control, are we talking like master keying? I'm not familiar with the concept. 

  3. Hey bill I can't find a mail or PM feature on the YouTube phone app, so I'm forced to ask the question in the open. 1: how do you thread the inside of the core? 2: is it at all possible to make a video on the subject of threaded cores. Thanks in advance and keep the awesome videos coming. 

  4. Amazing,i have to ask, im ordering picks and pick gun from southord a site you recomended, but i couldnt find any disc detainers, it took me a while to figure it out that my lock needed a disc detainer, where can i find one , and wich site is secure enought to order one disc detainer ?
    Thank you very much for reading this.

  5. Very interesting pin and curious as to its role. Maybe try to put it upside down and have some fun with it. Great picking and thank for the rake-to-release fault set pins technique :)

  6. Interesting lock Bill, the keyway is intimidating, even before you start! … well done as usual. The last cut on the key is relatively deep, it makes you wonder whether the strange driver pin would sit deep enough in the plug to bring the "second" ridge into play … Regards, Brian.

  7. is that a folgers adams key lurking in the background? We have some of those in the building I work in, was hoping to see a picking video or one.

  8. Wow bill your true leader in the locksport game im happy to be a follower your vids are so educational i have learnt alot THANK YOU VERY MUCH YOU ARE A TRUE INSPIRATION
