Found another candidate as a chain ring donor. Don't know where it came from, but it's been layin out back for about a quarter century. The small chain ring is still shiny and should clean up nicely. It's around a 40 tooth, which should put 2nd gear on the 4-speed around 1:1 ratio. I'd discard the big chainring. Then paint and reattach the chain guard. The made in Nashville Arkansas Roadmaster frame may have some potential as a single speed 26" cruiser. The top bar is right at 23" center to center. And it takes the 1 1/8 steerer, so I could maybe use the OCC chopper fork, and then an extra low mounted banana seat.
