Foam Cutter

I built this foam cutter to allow me to generate objects from foam. In the process of building it I noticed that I could add usability by creating different jigs. So I added a fence, a circle jig and a miter jig to extend its use. Finally I am happy with the range of application I can cover with this foam cutter. Thanks to its t-track in the fence I can add more jigs in the future if necessary.

Here is a video of how this cutter can be used.

Nice versatile foam cutter. Looks like it will work a lot like a table saw for foam. I should show this to my daughter in law who is in to that stuff.

nicely done, so clean,
is it heat or vibration that does the cutting?

It is a hotwire that heats to about 500-600 deg F. and then cuts the foam like butter.

I like all of it but I gotta ask – machine work or CNC on the fixture pieces ?

Definitively no CNC involved. I am a lumberjock not a machinist :)
My tools are mitersaw, routertable, disksander, beltsander, drill press and dremel.

So elaborate. Looks like a do it all center for foam.

I’ve only ever done straight cuts for inside walls. 6” taping knife, and a straight edge. Knife goes through the foam like it’s butta.
