I bought a Bailegh 18" bead roller. No way is the crank going to work for me. I'm thinking about adding a steering wheel geared down 2 to 1. It'll be on a shaft above the machine so that it will be on the same end as the rolls. I'd like to hear from guys with this type set up. Happy with it, or is power a must? If power how much do I need? This will only see moderate use.
