I asked in another thread and it seems the general tools for sculpting foam are saws and blades, with some people using hotwire tools occasionally.
It also looks like most guys are still using cork roadbed on top of the foam.
I was wondering if anyone is cutting roadbed out of the foam? If the roadbed was cut down into the foam the surrounding area would need less 'mounding up'. It could also be cut down and away as needed. A lot of roadbed does actually have a lower base layer than the surrounding earth anyway.
To that end, it seems like a little "car" or "cart" could be built to hold a hotwire shaped to cut roadbed out of the foam as it rolls over it. The wheels could be locked to any radius, or just straight. And if you wanted to get really fancy, gearing could be included so that as the cart rolled over the foam it would raise/lower the hotwire at a determined grade.
Anyway, seems an interesting idea.
