Hey Ron, some details from memory.
The motors are mounted end to end, with one motor connected in reverse. The roller was made from a short lenght of 25mm aluminum rod, drilled to suit the motor shafts and grub screws fitted at each end to tighten onto the shafts. The whole motor assembly could be adjusted from side to side to center the roller, and tension against the wheel was also adjustable. More tension reduces the chance of slip, but increases current ( increased current equals less speed and less range ). The trick was to back off the tension till it was about to slip.
Control was a single DPDT switch, center position off. Sit down with a bit of paper and you can work out how to wire it up. Dont forget to add a fuse!
