pic: Easy to make mecanum wheels

[mechanicalbrain]

I was wondering when this would pop up. OK the idea is basically to bolt mecanum wheels to tread instead of making a wheel (some people only have wood shops ). I'm pretty sure that if you have two sets of tread on each side you can get the necessary sideways motion. My only concern is the side stress on the tread. I don't think rubber will work. It is going to need to be plated tread which Ive been searching for. If anyone with knowledge on either tread or mecanum wheels could help me it would be very welcomed.
