need guidance

[Barnbikes]

Have a pulley off of a old grain cleaner that I want to use as a flywheel for a Rider - Ericsson type pump engine.

It it is about 20" diameter and and about .750" wide.


I plan on grinding the teeth off. It is not very heavy. I would put a .250" rim on it but do not have access to a lathe big enough to turn the outside true.

What size cylinder diameter should I aim for?

What pitch are the teeth. Could you put an old motorcycle chain on the OD for some weight? Would look cool in my opinion!
