bike peg mounting to motor shaft (friction drive)

[WaterDog]

How exactly do you connect a bike peg to the motor shaft? I understand the concept, I just don't see how you can connect them. I'm using a weed eater 25cc motor and I have the basic design down. I just need the roller now. Any advice would be helpful. Thx

On my w.e. motor i have a 5/16-24 threaded shaft coming out of it, I think I'm going to get a 1 inch diameter steel rod about three or four inches long and drill/tap it to screw onto the motor and run the rod thru a couple 1" i.d. roller bearing pillow blocks mounted to the frame via angle iron or something

in effect the shaft and drive roller will be the same part
