I fixed a radio

My 1937 Zenith 5S-127 radio uses a belt to drive the dial mechanism. The original belt was some sort of rubberized cloth that was disintegrating when I got the radio at an auction about 25 years ago. At that time I replaced the belt with an o-ring that I cut to the right length and glued. The glue bond lasted a couple months, and the radio has been sitting with an non working dial mechanism ever since.

Yesterday I opened it up, retrieved the o-ring, made some measurements, and 3D printed a new belt using TPU filament.



The radio is working again...



You can't buy a radio like this and expect it to work. I restored the electronics by replacing failed components many years ago, then refinished the cabinet.

This is what I should do with My Summa Sign D610 24 inch vinyl cutter.
The only differences is I need a Rubber Tire (" Tyre ") for the Pinch rollers.
I rigged three faucet washers together with rubber glue to form a single wide Tire around the original bearing this seems to work though it is not quite the right diameter.

You can do the part with TPU too ! To get the correct dimension , roundness, finish use abrasive wheel on a Dremel for ex. ABrasive is perfect to machine TPU.

I really like TPU. So many uses and it looks nice, too.

If only I could do this for my hi8 video cam

Cool
do you hear

Some one born in 2000 would never know what it is?

Put an arduino w blue-tooth in it, so you can listen to it with your air pods
and a stepper motor on dial drive, so you can tune it from an app!
