I'll try and get some photos soon, though the wheels are being very difficult at the moment. They are twice as wide as the shaft and I can't cut them down easily. Instead, I'm sawing them in half which seems to be working a charm. If all else fails, I have my eye on some other ones. The tape is merely to enlarge the drill shaft as the mounting hole is slightly larger than it. I can't do the melted nut method because I don't have a pillar drill, and the wheels Antazz sold were too small. I still need to paint the sides and mottom, properly mount the wheels and motors, shock mount the electronics and make a cradle. So much to do, and so little time.
