Very cool video, jig & tying vise! I also have one of those Universal #2 vises, but don't tie on it a lot as I use an old Regal Medallion the most. But those Universal vises are work horses!
I have several old vises, most bought with estate lots of tying supplies. I had planned to sell them, but decided to keep them, for teaching tying classes. Have some older tools too, like Herter's & Chase bobbins. They're all still very useable.
