soldering vise - third hand

This is a small solder vice with changeable jaws for round workpieces.
Also well suited for all other craft work.

The spindle is M6 and the guides Ø8. I used Allen screws as guides.
The compression springs are Ø8x20. (They were still lying around here)
From the bottom are holes for Ø10x2 Neodyne magnets. But, I have not used it yet.
