Not a lot of point in finding a 'donor' set since the gear in that one
is likely broken or will break sooner or later. Nylon gears pressed
onto plain shafts are very prone to snapping at one of the roots
simply beacuse there is a constant tension in the plastic, flow
boundries and stress risers due to the gear shape.
I have had good luck finding brass gears that are 'close enough' for
these sorts of applications from other junked mechanisms that have
gear boxes in them. Anything from VCRs, copiers, printers [especally
laser ones], paper shredders and so on are a rich source of gears and
bearings.
