I have just begun the process of converting my non-functioning dash clock to battery-powered quartz movement. I have the movement out of the case, but can not remove the minute hand/medallion. In prior 'brand X' conversions, the hand simply pulled off the shaft; any suggestions as to how to proceed? Do I need to loosen the movement, separate the shaft from the movement and pull the shaft out from the face along with the hand?? Any suggestions you may have before I break the thing will be appreciated....

As you say, most the clocks I know, have hands that you simply pluck off the shafts. I've never tinkered with a Stude clock of earlier than '53 vintage, so I can't speak authoritatively on how you 51's clock dismantles. I have seen clocks where the very end of the longest shaft had a threaded finial on it. Once that was unscrewed, then the hands came off as usual. I think this was on a clock out of a foreign auto tho.[B)] MAybe someone else will chime in here with some hands-on insights. Let's hope![:I]

I got my car's clock restored by an old friend who is retired, but a real star. As an eighteenth century clock specialist (of great repute) I thought that he wouldn't take much interest, but when I called him he said "Oh YES! Those electrically wound, clockwork clocks are MOST interesting!" He made a slight modification so that it would last 100 years more, but I'm afraid I couldn't give details of what he did.

Did he give you a "warranty" on that 100 years thing, Peter? [}:)]:D

Well, I'm well along with the job of 'rendering' my dash clock from 6volt to AA battery quartz movement, preferably one which is not more than 1/2" deep. Here's what I did, in the hopes I can help/encourage others to resurrect a dead clock.

Remove trim bezel by prying the 6 tabs up. It's messy and I wouldn't be surprised if I have to solder the thing back on later.

Remove guts of case. Turn up the tabs holding the movement to the back of the face. Between the face and movement cut the stem which leads to the hands with a hacksaw.(face turned white yet?) Remove the old movement housing from the back of the case.

Cut the stem off at the base of the ornamental minute hand, grind it flat with a dremel, then drill a cavity with at 9/32 drill bit. A common cap nut used with these Japanese quartz movements will nest in the cavity. Glue it in place to the back of the hand. This will now screw on the shaft of the quartz movement and serve as the 'new' minute hand. Attach the new movement to the back of the face. Insert the face/movement back in the clock and mark the approximate location of the battery cradle.

Make an insert matching the inside back of the case. Drill a 1" hole in it about where the battery cradle would be.

Now you want to make a 'fake' battery. Cut a 3/8" dowell rod about 1 7/8" long. Locate small wood screws about 1/2" long and drill holes in the ends of the dowell to accept screw. Go to Radio Shack and get a AA battery holder. Crimp the ends to a 16-22 loop connector with hole appropriate to the screws. Assemble and place in the battery cradle of the movement.

Place the insert back into the case, mark/drill/attach three sheet metal screws in spots not interfering with the new movement.

Smear a healthy dollop of glue on the back of the movement, avoiding the time adjust knob. Thread the 'remote' battery cradle through the back of the case. Center the movement/face in the case and seat to the insert. Let dry.

Glue or tape the battery cradle to the outside rear of the case. Add a real battery when the time matches what the clock hands say. That's it! Now you can:

1. have dead accurate time regardless whether car battery good, bad or out of the car.

2. replace the battery easily when it runs down

3. service/replace the movement without having to do any major demolition in the future.
Good Luck!

No written warranty, Mr. Biggs, but I am quite sure that if I call him in 100 years and say that it isn't working, he'll fix it like an angel.[:o)]
