Re: rubber drive roller or steel?
I don't have enough experience with friction drive to help you masterx. When I first built the Jdog I made it a friction drive and used a fence post as a drive wheel. Worked okay just did not like the friction drive so I swapped it over to chain.
I would think the rubber drive wheel would work better but I guess the steel one would last longer. But with out having much time on a friction drive and never using a rubber drive wheel I just don't know. Be patient I am sure others with more experience will jump in.
