It's function is to improve chain wrap on another sprocket. I don't know if there are any common PVC pipe sizes with an ID of .375. Do you think turning a Delrin piece to go around the shaft would work?
I think the GDC should force us to use steam engines, but the electrically-inclined folks on my team might stop whining if they're given more to work with. - Madison [more]
