I need to hold small jewelry items for laser marking but couldn’t find a suitable vice for holding them. What everyone is using for such applications…any suggestions please…

Alligator clips?

Maybe something less affected by heat for laser marking.
What about Tesa Power Strips or Frog Tape?

i tried glue/tape also hard wax but heat is a problem…when engraving…

i have also tried clay but sticky/oily marks are a problem as the marked items have to again refinished…:frowning:
