Again thank-you all for swift replies (yet again Gary!)

So using the floor as slip - I will use the toothed belt system.

The motors I've purchased are modern replacements for the GPA 750 - apparently their application is belt drive systems in wharehouse machinery (perfect suitor it sounds like).

I have done some calculations (with a few pointers from some mech mates) and it looks like I can drive the wheels without a gear box - is this wise? I find the simpler the design the less can be damaged.

Is there some magical formula regarding belt tooth count in relation to size and pulley teeth? Or am I hoping for the impossible?

I am finding knowing the name/source/brand of items to buy far harder than the physical design!
