I'm looking for a 3rd hand type tool.
I've used them before, but forget the exact name of them.
Its similar too the 3rd hand thing but instead of alligator clips, it has something that looks like this:
The hole in the piece there is where it slides over the shaft that the alligator clip "assembly" normally goes on.
It uses 2 of those pieces.
They both slide along the shaft so you can set it to whatever size the PCB is, and the groove in them is where the PCB goes.
(Now lets see how long it take before someone makes a sexual reference to what I wrote
