Default Re: Modifying Friction Drive To Accept GEBE components

I've been informed that the GEBE drive pulley's ID is 5/16" fine thread. :detective:

That won't slip onto my 1/2" diameter jackshaft. Unsure if this pulley can be drilled 1/2", then welded onto the shaft.

Does anyone know what the OD of any or every GEBE pulley is? I need to know the diameter where the belt rides, and the diameter of the outer lip.

Maybe I'll be needing to search for a pulley and belt elsewhere, which would work well with the GEBE ring's belt grooves. :detective:
