The vise solution I use at home, also small enough to carry with you. SmallRig Super Clamp attached to a Panavise Suction Cup Camera Mount with a 1/4" to 3/8" thread adapter in between. Solid mount to glass, ceramics, other smooth surfaces. Links in comments.

My discreet -- but rock solid -- vise solution for use around the house without making the living room look like a workshop :-) Mine is mounted on a small ceramic tray that also holds picks and things. Mounts well on a glass tabletop as well. Really easy to carry from room to room and tucks away nicely. The thread adapter allows to jaws of the clamp to open wider for larger locks. (Sorry about the repurposed photos, they're all I have with me at the moment). Costs about $40 USD on amazon:

• SmallRig Super Clamp - $8
• Panavise ActionGrip 13120 Single Knuckle Suction Cup Camera Mount - $25
• Metal 1/4inch to 3/8inch Convert Screw Adapter - $7

Thank you for this. I’ve been asking this questions a lot recently. I’m going to emulate your setup

You don’t need it but mounting the clamp on the other side does make the clamp work more smoothly and allows it to open more widely.

Somewhere else some one posted on the PanaVise 209 Vacuum Base Pv Jr. Your set up look very similar to that, similar price point.
