Hello everyone ,
I have a 1955 Ford radio (Model 5MFS-2 google this for pictures ) from a 1954 Ford Thunderbird.It uses a permeability tuner which makes the pushbutton tuning facility easy to engineer and therefore probably cheaper.
But the set has two problems . The first is that the three threaded brass shafts in the tuner which locate the 3 ferrite rods in the 3 coils, turn in, and are located by, threaded rubber grommets. These rubber grommets have, in the intervening years, become hard as rubber that old is prone to do . And have disintegrated. So that when the oscillator is tuned to Magic the antenna is tuned to Coast and the r.f. stage is tuned to Rhema.
I think I have solved this problem,luckily finding some brass nuts to match the brass shafts.I think I can embed these nuts in daubs of RTV where the old grommets were and ,once the RTV cures , get the ferrite cores to dance in step.I will let you all know if it works.
The second problem is harder.The radio came without any knobs.It seems to have the same knobs as many other American Ford radios of that era.So Ford Customline radio knobs look like they will do the job. I mention that because Customlines were sold in N.Z. Does anyone have a set of Ford Customline or similar knobs they would be willing to sell?Or possibly lend with a view to 3D printing.They are press on types with 1/8 shafts.I suspect there may be at least three as the volume control and tone control are that combined type. The inner knob has a 1/4 inch hole. All the pushbutton knobs are there -it is only the tuning,volume and tone knobs I need. Cheers everyone.
