Prof that's what I wanted to hear.... I still think about building the super simple friction drive and now that I know my chainsaw build was too weak the bigger drive shaft appeals to me.
What are you waiting for? Buy one at the sale price and do it. You can't go wrong with this engine at that price.....and even with it's lower RPM, this thing has good power.
The sale has ended. I'm going to wait to see if they put it back on sale. I'm not in any rush. I need to figure out what I'm going to use for a roller and how to attach it.
