Part of what I'm doing involves the cutting of foam. A lot of foam. I did the design to take advantage of the natural scoring in the XPS sheets (the 2-inch sheets are scored at 16 and 24 inches from the long edges) which minimizes the cutting and assures nice straight edges, but cutting a lot of XPS is a pain in the ass. The hot knife is good because it's a hell of a lot faster than the razor knife-- probably twice as fast-- and it doesn't dull like the razor knife does.
But those long, straight cuts... there has to be a better way. You know what would be perfect? A knife that rolls, like a circular knife that's on a handle, like a... a...
Okay, to be fair it's got to be a pretty heavy-duty pizza cutter. To cut through 2" foam, the wheel has to be over 4" in diameter, and I was only able to find one 5" diameter pizza cutter online. But dang, I was actually able to find one online.
I'm gonna try to pick up something tonight. My pizza cutter at home is too small. I'm thinking Target. It will probably still not be big enough to cut through in one swipe, but I can do a couple. Worse comes to worst and it doesn't work, then I'll just have another pizza cutter.
It's kind of odd: after this, I will end up with quite the collection of foam carving tools. Then again, maybe that's not so odd.
What I've discovered that surprised me is that foam has become an architectural thing, like a lot of architectural detail is actually carved out of foam and coated with a kind of plastic. This intrigues me.
Okay, enough for now.
