Third hand PCB vise

thingiverse

This "Third hand" tool (http://www.thinkgeek.com/gadgets/tools/a4bb/) has a magnifying glass I never use, but its PCB vise intrigues me. I adapted it for my needs; however, the base isn't very sturdy. A full vise may be in my future. To create the vise, I drilled undersized holes and used guides from an old spotlight rail (or any 6-8mm tubing). Secure the position with two M6 hex bolts (15mm or custom length), tapping a hole first if needed (drill to 5mm, then tap for M6).
