OK, after going back and reading Greg/MOs instructions and FOLLOWING them this time, I have made another attempt. I need a new motor. I've tried two. One is too fast one is too slow. I'll try a variable speed next time. I put a rheostat on the fast motor but it didn't work, the motor didn't have enough windings for it to be effective. Anyway, here are the results. I hope they get better with experience. If not I go back to reflective tape wraps.
