Re: Innexpensive crab module?
You say that you will be using drill motors. Will you also be using the drill transmissions?

If you are you may be able to direct drive the 4" wheels to the drill output and save the cost of chain/belt/pulley/gears.

A chunt of plastic such as Delrin or Nylon can may a good inexpensive pivot/thrust bearing for your crab module and it is much cheaper than roller bearings.
