Interior clock from GAZ 21
Here is a little story about the clock from the car Gas 21, which I recently bought and burned in the home interior. It is electromechanical clock, needs 12 V to work, consumes about 3A current when auto winding, then the coil is de-energized. In general it is an ingenious creation of the Soviet times. The clock is from ’69 and still working. I can not say that I bought it in terrible condition, no, but the chrome on the bezel is a little rusty.
First I made a LED clock backlight. As standard there are two bulbs which irregularly and dimly light the scale. To make it all right, I cut a ring out of cast iron with crowns:
In sprint layout program I drew a schematic diagram:
Etched and tinned, then soldered LEDs and varnished:
Then painted the bezel black mat and assembled everything:
Next, the enclosure needed to be made. For a long time I was thinking that if the watch is round then the case should also be round. I bought in a store a metal muff for ventilation.
It is very difficult to make a perfect circle with a jigsaw, that’s why I made the inner hole with a crown:
Silicone sealant adheres well to metal, tested, so I fixed the ring with it:
When the sealant has dried, you can turn over our workpiece and fill the groove with polyester putty with fiberglass. We use a metal spatula to apply it:
sanding and painting with powder matte paint
The clock is attached to the ring on the back side with self-tapping screws through the original lugs, which had to be trimmed a little. Screwing it to the front of the kitchen cabinet:
Made in the USSR. 69 year clock from GAZ-21 car into home interior.
I bought two years ago on an automobile forum a clock from GAZ-21 of the 69th year. The thing is not to say that the direct rarity, but I got them in very good condition. Well, why I bought it, read below)
The GAZ-21 Volga was a Soviet car of the middle class, mass-produced at the Gorky Automobile Plant from 1956 (1957) to 1970. This watch was installed in the car:
My watch when I bought it from the garage looked like this (seller’s photo):
The watch is a ’69. They had some chrome on the bezel and some rust on the case.
Decided to first sand the bezel and paint it black. The paint used was “Montana Black” for graffiti, it is very dense and has a texture after drying, also does not require priming:
Next, I took the clock apart to check the condition of the movement, but it was in perfect condition:
The watch is electromechanical, needs 12 V to work, consumes a current of approx. In general, an ingenious creation of Soviet times.That is, the coil winds the mechanism with a spring, and as the mechanism works spring compresses and contacts closed, thereby energizing the coil to wind the mechanism, a click is heard. The winding is carried out automatically every 5 minutes.
Now, about the backlighting of the watch. As you can see there is just a faint incandescent bulb inside the watch, and it glows like this:
I decided to make a LED backlight, drew a board, etched and soldered LEDs:
In the case of the watch it went like this: I coated it with varnish:
Put everything back together, plugged it in:
Now it was necessary to come up with another clock-fastening case. At first I wanted to make it from plywood rings, but unexpectedly in a plumbing store I came across a vent flange made of metal:
But the diameter of the hole is larger than the diameter of the clock, so I cut the ring out of plywood and glued it inside with sealant, since it adheres perfectly to the smooth surface of the metal:
Now we need to “smooth out the corners”? using fiberglass putty with hardener:
Then a 2K automotive finish:
After sanding and painting:
Now we cut a hole in the facade:
Using the regular lugs on the clock, screw them from the inside to the plywood ring, and screw the case to the facade:
It remains to shorten the flexible shaft, which is responsible for setting the clock, run the wires, and make a cover for the back:
I used a CD box cover, sealing it with sealant. Wired with self-adhesive pads and clamps so that there was a sliding attachment when the door was opened:
All this stuff is powered from a low-powered computer PSU, which I bought at a flea market.
And the result: At night:
The clock has been working properly for three years.
