Oh Yeah- cutting the styro

[IDMiamiBob <IDMiamiBob@aol.com>]

I found a soldering iron with a one inch long "blade" tip, which heats up and
hot-knifes its way through the styro very cleanly.
A combination square will be useful for measuring off the styro and for
providing a straight guide for the knife/soldering iron.

They are both available at hardware stores.
