FFV8 love your idea. Here is another Goldy did ..............Curt
The band might not be necessary if your clutch drum sticks out past the hub far enough (about 1/8")
There was a hole already in my clutch hub that I simply tapped 1/4 UNF to fit the pawl screw...upon final installation, I peened the end of the screw over to prevent it from unscrewing and falling out. The roll pin prevents the heavy side of the pawl from contacting the drum when running and also provides a point to fasten the return spring. I use a rare earth magnet to hold the pawl in the disengaged position when pedaling , or pushing it around. Also the heavy end of the pawl rests on the central part of the clutch hub when in the engaged position, I figured this would give it some extra strength and take some of the strain off the drum.
