Well with working out of town for the last 6 and a half weeks I have not had the time to put the finishing touches on the wheel changeover until a few minutes ago. I did put a few miles on the wheels and I am very pleased with the results. I must first state how difficult it is the mount the sheave on a rear drum Worksman Wheel. I had to purchase the sheave mounting clips for a vintage Whizzer with the 5" rear drum brake. They are not cheap and do not fit exactly the way they should. I did finally get the sheave mounted but I will be checking it frequently to make sure I don't have a catastrophic failure. The other issue was the brake cable adjusting fixture. The stock adjusting fixture is not usable because it puts the brake cable at a very sharp angle and is at a very tight spot in the frame. The brake arm itself is another problem. I was able to clamp it with the brake arm clamp from a Whizzer coaster brake setup.
It will be much easier to mount the sheave on a Worksman coaster brake wheel. The only modification needed for that is to enlarge the spoke groves on the mounting clips for the larger spokes and use the Whizzer brake arm. The front was much easier but you still have to be creative with the brake arm mounting. Be very careful to make sure you keep the distance correct between the forks. If you pinch them in or splay them out you could have a catastrophic fork failure.
The Worksman Wheels are a big improvement over the stock wheels as far a strength goes but installing them on a Whizzer is not an easy task to say the least. If you are not comfortable with tools and modifying things you should probably not try this yourself.
I'm glad I did because it changed the whole feel of the bike.
