Nothing too spectacular but here is a shot review what I did.
|First I cut the foamboard roughly with my electric jigsaw.|
|As a kind of ruler for the hotwire-cutter I fastened to beads on top and bottom of the foamboard.|
|Then I cut the overlapping foam with the Thermocut.|
|The wire of the cutter is rather soft. Therefore in some parts the cut wasn't smooth. So I sanded it a bit.|
|After removing the screw clamps... A clean and smooth cut.|
