The radio looked so nice on the shelf so it was worth putting right, so off to the shed to look for a suitable piece of brass to make a new pin for the handle fixing. In the end I decided to sacrifice this old control extension which happened to be 1/2 inch diameter.
It took a while to dissemble the radio, the manual said unsolder the speaker and aerial wires, remove the 3 screws and pull the chassis down. Two screws were easy to find but the 3rd eluded me for quite some time.
Here is the original pin.
Here is the new pin on the left and the original pin cleaned up prior to polishing and spraying with lacquer which I will now do tomorrow. The thread on the new pin is much bigger than the original one because 4mm was the smallest decent die I had, but that is not important as it is hidden in the case.
Whilst the radio chassis was out I had a look at why the tuning was so stiff. I oiled the cap bearings and waxed the cord where it went over the simple peg guides.
The concentric slow motion drive was still slipping in its bearing though. I fixed it by relieving some of the tension on the cord. On this radio the cord only operates the tuning pointer as the slow motion drive is part of the tuning capacitor spindle.
Now tuning adjustment is now nice and smooth.
I am getting quite fond of working with the lathe, brass is a lovely material to work with, the little lathe copes with it much better than steel.
