Introduction: Styrofoam CUTTER
This is my invention for cutting foam moldings.
It also works with polyurethane baseboards.
Step 1: Parts
The main part is the heating nichrome wire 0.4 mm. I bought it on this online shop:
And of course the bench power supply from my last project:
Step 2: Frame
I made a wooden frame from boards 100 x 20 mm. Just because I had had it :-)
I made a gap 5-10 mm for adjusting string tension. And a one screw for it.
Step 3: Washers
I used square and round washers and screws to fixing nichrome wire between them. And made small groove for wire.
Step 4: Cable
A cable is connected to the ends of the nichrome wires.
Step 5: Base
The base is made from plywood and the simplest hinges.
On the base I marked lines for 90 and 45 deg angles.
Step 6: Result
I provided 9V, 3.38A for foam cutting. In the picture is more for red light :-)
Done! Please, watch the video! Bye!
