I did a search on GJ but didn’t find a discussion on this vise
But here is what I got for $16. I took it apart and put some grease on the screw and contact areas.
I know there are tiny vises like these but the jaw on this rotates.
I purchased the exact same blue swivel vise from Harbor Freight about four months ago, and have not had good luck with it. When I attempted to use it for the second time about two weeks ago, the lower clamping arm of the casting broke off when I was attaching it to the very same portable welding table as shown in your picture.
Sadly, this vise wasn't even able to withstand a normal amount of torque from simple and conventional hand-tightening. I couldn't return it for a replacement, because it was two weeks past Harbor Freight's ninety-day return policy when it broke.
In order to make it usable, I ground down the remainder of the clamping arm in order to make it flush with the bottom of the lower swivel base. (Now it can be screw-mounted most anywhere) This wasn't an optimum solution for me however, because I already have a stationary bench-mounted vise that I use for most things. This little swivel vise was purchased for its features and ease of portability between various locations, the latter of which is now compromised. That being said, I got the thing for $14.99 with a 25% off coupon, so I might take a chance on buying another one...
or the one where other reviewers said it broke when they tried to press straight some bent angle iron or use it press crimp off battery cables.
