Homemade Cat Wheel??

I was wondering if anyone has any somewhat simple plans for a homemade cat wheel????

I did search through some posts and found one post that the woman said to PM her for the info....but it does not seem she is an active user on here anymore. (for over a year now).

I'll pm you on the one I have (from a TCS member) - we are working on building one now - its slow going as we had other things that were more pressing, but hope to finish it by end of the year.

We were considering building them and selling them, but its more work then we realized.

There was one in the Market area, a guy was trying to get rid of. It's large, but.. um, it's the only one I've seen!!
