modification is so easy and doesn't require any extra parts.
Modification to GBC-H220 laminator for making prototype PCBs is shown in this video:
GBC-H220 Gear Modification for Printing Circuit Boards
But I missed the boat on getting one by a couple years, it seems. They seem to be obsolete now. So I will look forward to your applying the board Harvey recommended to getting the laminator slowed down and to what modification you need to make to get the temperature to the value that works for PCBs.
