Jewel 935 Clock Radio (1950)

This is another ebay item. I got this one for $8 and assumed it was bakelite and that it would require cleaning, painting and perhaps repair of a crack or two. I don't usually buy clock radios, but I was looking for one I could put on my nightstand and had recently read an article about repairing the Telechron rotors used for the clock's movement.

Its funny, but the radio was in much better shape that I had expected, but at the same time it was far dirtier that I had thought. The parts of the radio that look black are really dirt and as it turns out, this radio isn't bakelite, its plaskon or another type of ivory plastic.

This picture shows the Telechron movement installed in its laminated metal transformer housing upside down. The small gear sticking out drives the clock gears underneath. When it arrived, the gear did not move at all, probably because whatever oil that was originally used had gummed up. These rotors are not designed to be serviceable, but they can be serviced with a little bit of heat and oil. I had read that one could use tip of a soldering gun to heat up the rotor and that you could place a drop or two of oil on the gear which would be sucked into the rotor by the vacuum created when the rotor cools. I didn't have a soldering gun, so I used the element from an electric stove burner. I heated it up for 45 seconds and then pulled it off and set it on a heat sink. I started to wonder if it was going to turn now and looked at the laminations from the transformer where it came from. The laminations were such that I could insert it upside down, plug in the clock and see if I got movement. It worked and so I repeated the adding-oil process several times. All functions of the clock now work well.

This is the "all done" picture. I had to wet sand the bezel around the clock and paint it with Krylon Brass as the finish was too far gone and there was rust. I filled in the "Jewel" logo with a plum-colored Crayola crayon from my daughter's crayon box and wiped off the excess. The radio dial markings are original. There was one small hairline crack at about eight o'clock. I tried to clean the line with bleach, but it never really improved. Fortunately, its barely noticeable. I don't know if the radio selector knob and the volume knob are really supposed to be that color, but I doubt it. I think the plastic has just reacted with the environment and discolored. The clock knobs are much more white and are probably what the other knobs originally looked like.
