The Worcksman wheels I have did not come with sprockets. I have sheaves.
My Worksman wheel came with a 22t freewheel, Whizzer also put a 22t freewheel on
The freewheel is for the pedal chaining. The sheeve is for belt drive
I put a White Industries 22t Freewheel on my Worksman Wheel
However you mount the rear sheeve the Idea is to get it perfectly centered on the wheel
When using the Worksman drum brake freewheel and the modern Whizzer sheeve mounting brackets,
1 spoke notch won't line up and you'll have to make another notch on the brackets
Tip make the notch with a grinder or round file
Yes I've got the rear sheeve mounting figured out as best I can without the factory mounting tool
I guess you must of seen a thread or post I made about it
Basically after you've mounted the rear sheeve on the rear wheel as centered as you can with measurements
Mount wheel on bike with rear belt off - Using a Run Out Tool -
By loosening and tightening one bracket at a time where needed - tap the sheeve with a rubber mallet to align it.
Put the rear belt on and spin the rear wheel or start the bike, the clutch arm shouldn't bounce, you know the sheeve is perfectly centered
Perfection can be hard to achieve, 1/8" clutch arm bounce is acceptable.
