New Treadwell Build

[deathproof]

Here's a question: Bloody Plastic's Treadwell build used 3" PVC couplers as the wheels, filled with foam. Seems a logical way to do it quick, dirty and cheap so I will likely follow suit.

Question is: What to use for the treads? I can't afford those blower motor belts (around $125 each, IIRC) that they used for the actual droid in ANH. Bloody Plastic used some sort of rubber mat from Home Depot, cut to size and stapled together. That seems fine to me, but I have no idea what sort of mat he used.



Any suggestions? I need something that looks like black rubber treads but preferably on the cheap side.
