Has anyone tried cutting Auralex foam with a table saw and a cross-cut sled?

Before I moved out of my old office building, I went dumpster diving and picked up a handful of Auraex panels from a radio station that had thrown them out. They're too large to sit neatly on top of my monitor stands. That said, they do an excellent job at reducing the coupling with my desktop. So I want to cut them down.

I've seen the advice about using an electric turkey carving knife, but I don't have one. I do have a table saw and a coss-cut sled.

Unless anyone has any specific negative experiences, I'm going to try it this afternoon. My plan is to go very slow and see if I can get a clean cut.

What's the worst that can happen? #TommyCaldwell

Freeze it first...

Otherwise it looks like this

Interesting. I have lots. I'll try it both ways. For science.

Or maybe this is a more practical solution? Not sure if the damping is quite as good since there is more weight in the foam which compresses it a bit more. It definitely looks more stable.

So, I wouldn’t necessarily recommend this as a way to cut Auralex foam. It works, but you have to be pretty careful. I’ll upload two videos to show what the deal is.

Hmm, how about a heated wire or knife?

IIRC this stuff is easy to cut with a hot wire styrene cutter. I used to use one to cut up the foam I used to store my Warhammer miniatures. A bread knife will also work but the cut ends will be a little sloppy looking.
