Dial cord spring for a Grundig Satellit 650? - UK Vintage Radio Repair and Restoration Discussion Forum

netsmo62 · 25th Sep 2021, 2:00 pm

Hi, during the work to restoring a satellit 650, dial cord spring broke. Unfortunately no one of my spare parts dealer in Europe for Grundig radios have one, so I ask where i can find it. Dimensions are about 2,5 mm OD and about 15 mm lenght with hooks. I have searched on two suggested sites I have find here but minimal dimensions are bigger than I need...someone can help me?

Thanks in advance, F.

If it has broken at one of the hooks, it should be possible to bend the end turn 90° to make a new hook. I have sometimes done this when no suitable replacement was to hand.

Retractable ball-point pens are a good source of all sizes of springs.

The spring from a retractable ball-point pen would be my starting point.

Unfortunately has broken in three pieces...no way to recover it.

I have already test it. Pen spring is too big in comparison to original one, dial cord on 650 where spring connect the two hooked sides run very close to chassis so why spring must be so little in OD.

If you have a spring that has the right diameter size of wire, you might be able to wind your own spring, using the shaft of a twist drill as a mandrel. You would need to use a somewhat smaller drill as the wire will go back slightly. I have done this in an emergency, clamping the drill and one end of the wire together in the jaws of a vice before starting to wind.
