Found a good use for my non repeating cheap import Telescopic gages.

Great solution to a common problem.
I keep a small jar of various small compression springs near my mill. I use them the same way you're using your telescoping gauge.

When all else is too big, I use a short piece of flexible tube. Works with the vise either horizontal or vertical.

I like that. I've got lots of scraps of tube in various sizes. Doesn't even have to be tubing: sections cut from plastic bottles would work.

Rubber bands around the jaws and parallels
They don't hold up the best but work at any jaw opening

I most often use old banding from boxes & pallets.
Cut and bend a spring to suit the gap. When I'm done, I throw 'em in a plastic bin for the next time.

I use the banding too for smaller gaps (and sometimes larger). And flat brake drum separator springs are usually used for larger (down to near full compress), with spacers to provide more width. The spacers are generally "shop made parallels" I started making a long time ago from short remnants. Mostly just fly-cut mild steel for the squared up parallel faces, they get used for common drill projects, shimming weldments, and such non-precision precision stuff. They tend to be around vise jaw width so easily span the gap, and thick enough to lay down sideways to combine with the flat spring for supporting low parallels. Also great on the drill press (or tacked onto something) since they are casually sacrificial, and can be touched up or reused for other things as needed.

I use rifle magazine springs, the flat ones.

Moved the Chinese telescopic gauges from the metrology shelf to the drawer next to the mill. Is the only functions they may be good for; that and as bouncing hammers.
