WOW! You all must be reading my mind. I want to do the same thing. Where did your big wheels come from? Anyone have a design for doing this? I tried googling hometrax and got nowhere. I was figuring on taking big PVC drain pipes in 10' lengths and just using them as rollers. BUT it did not seem really very likely to be successful. I LOVE the idea of making my own wheelset. But I am going to need more design ideas than what I have now! THANKS!
