I’ve got some high density foam and the age old tomato can cutting is going great. I’m wondering what the best way to cut strait lines in the foam is? i.e. I need rectangles of various size. Note that one of the rectangle sizes is a bit narrow: 1"x6". I’ll be using this slot size to fit test tubes that will house string… Yes, it will be awesome IMO.
So far I’ve seen a technique employing a “hot wire”, but I don’t think that this works for the type of soft foam I’ve got. It looks to be a successful technique on more styrofoam-type material, but I suspect this would not work with the type of sponge-like foam I’ve got.
