Ridgid Insulation Cutting Examples From Youtube.

Not cheap but may give some an idea or two.

I like this one.  Easy to get angles off of the tablesaw or skill saw.

Yeap, we use putty knife on polyiso up to 2" thick, it's just awesome for bevel cuts :)

I had in mind something like this. You'll have to excuse me as my photography skills are only slightly better than my 3D modelling skills (which are totally nonexistent.) Imagine the pice of cardboard I hold in my hand here is roughly the size of the piece of cardboard I'm holding in my hand—maybe a little bigger, the inside edges will need to be slightly more than 2" to cut 2" polyiso board. Also imagine the blade is around double the size of the one I'm actually using in the picture, whatever the size snap-off blade you'd usually use to cut polyiso board would be.

Also imagine there are two slots in the right-angle, one to set the blade to 30º and one to 60º. All you do is print one of these in your 3D printer, insert a blade, then pull it down the edge of your panel (as I'm illustrating on the edge of the table in the last photo there, don't tell the landlord.)

You've just cut a perfectly beveled edge with almost no effort and no tools aside from a simple 3D-printed part and the blade you were going to use anyway.

Can anyone who knows what they're doing model this and throw it up on Thingverse? Extra points for taking account of the non-90º angle at the point of the blade where it's seated and getting the correctly angled slots for doing 30º and 60º cuts into 1", 1.5" and 2.0" board.

Cheers, Robert.

Very cool! The longer you make it along the edge the more accurate things will be, I am thinking 2 ft should work nicely.

I was thinking about 6" would be plenty—and be small enough to fit on the bed of most 3D printers.

Cheers, Robert.

I wonder if you could mount a large pizza cutter for the same effect:

That one has a plastic blade but I'd think a metal one would work well.

Pizza cutter at an angle, mounted on a flat thick piece of wood with an (angled) axis? Would that, erm, cut it?

[Rob Gordon]

I don't know  hopefully someone will try it or has.
