Re: Friction Drive Encounters Oil
You could keep some rubbing alcohol and a clean rag in your tool kit to degrease the tire and roller. I don't know if cutting some shallow cross grooves in the wooden roller with a dremel or rasp may help.
I have found the pavement where the big trucks wait for traffic lights to stay pretty oily.
