Timing Belt Drive System

[maclaren]

We are looking to build a timing belt drive system and I was wondering if anyone has built one out there.

What type and size of belts did you use?
How many wheels were in the drive system?
How did you tension the system?
What problems did you have?

Just curious what peoples experiences have been with a drive system like this.

We are planning on making a six wheeled drive system with spring loaded tensioner and serpenting the belt around the drive sprocket and the wheels. I haven't looked at had size or profile of belt we are going to use yet. We plan on using about 8" drive wheels with about 7" wheel pulleys. Yes we plan on either having spokes on the wheel pulleys or making them hub-less. We are planning on using live wheel with fixed axle and attaching the wheel pulleys to the face of the wheels. We have not decided on what wheels we are going to use ideally we will use a fully custom wheel made at our machine shop and then rapped with rubber from a local rubber mill we work with.

Thanks for the feed back.
