Tandberg 3001 tuner - broken gear

r that drives

list, so I

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.

Plastic gears can be repaired by melting new nylon or derlin into them with a soldering iron, even missing teeth, and cracks around the hub can be prevented from reappearing by pressing a ring of metal around them.
