I suppose I should have mentioned the roof was designed (if that word actually fits this hack project) to be removable. I built a basic mechanism for the blades, and put a couple of levers on it that are hooked to nothing, but because of where it is mounted it is difficult to see the levers, let alone what the rods are connected to on the other end. The small blade on top is a dremel cut off blade, and the drum that the drive belt will hook to is a rubber sanding drum from an old kit I had lying around. The belt between the 2 blades is masking tape, triple layer, epoxied and painted flat black.

and one of the roof set oblique. I could not imagine having an issue inside a building this size without a loose roof on it.

Did I forget to mention the handiness of a flat bed truck when working on a project like this? I can not imagine a better work bench…
