If you recall my Westclox clock didn't work and it was not possible to take apart in an easy way. So I decided to convert my old clock to a modern quartz and I didn't want it to be too obvious. However even though the clock is now completed I still need to replace the pointers as the ones I'm currently using are not looking stock. Will think that part through one more step but wanted to share the current layout as it is now.

Using a quartz clock from a German manufacturer, price around  six USD. Took it apart and used only the quartz clock, as the battery holder for the AA-battery would make it too large for the Westclox housing. Then I bought a battery-holder for LR1 batteries. That's the best size I found, for a 1,5V battery, glued it in the bottom of the Westclox housing. Then it was all down to fitting it together. Except for the pointers you can't tell its been converted and its easy to replace the battery and set the clock. Its also stopping the drain on the main car battery...

Excellent job Anders!!! It's sometimes so much more rewarding to fix and execute a repair and improvement such as you've done here. Could have easily been sent out but this is the type of thing that is enjoyable, for me, working on our cars.

I think the hands look fine. The average person will have no clue of the difference


Problem is; you and I are not average...

How many people will you meet that will see the difference Anders? Leave it like it is when you are happy with it.

Kinda agree. Nobody would know... except me every time in the car.

Have the hands on my desk. Will try to modify them.

There is no rush as I'm not gonna be using the car until late April anyways. A little more than a week ago we got about 50 cm / 1,5 feet snow. Its melted now, but they think we will have a severe winter. So both cars are parked for the winter.

Time is running out on you LOL
Is there a 12 volt equivalent to that type of clock? I hate changing batteries in my home clocks let alone my car. LOL

I'm not aware of any. If I would have found a 12V quartz clock then I would have used it. Was looking for a 12V to 1,5V small transformator as well before settling on a battery.

Radio shack use to sell those lighter adaptors where you could select 1.5, 3, 4.5, 6, 7.5, or 9 volts. They were kind of cumbersome if you needed to hide something but in a pinch remember taking one to power a 6 volt auto reverse cassette player I had worked into an alarm system (long story!). Since every thing was tucked under amp and alarm boxes it didn't matter. If you are into wiring you can also simply use resistors to build a voltage divider circuit.  I did some quick math and it looks like a jumper wire between a 10KΩ and 1.5KΩ resistors would get you in the ball park. (1.43KΩ would put you almost exactly on 1.5 Volts).  Somewhere between a big bulky DC 12 volt lighter transformer and a crude wiring between 2 resistors, there is probably a simplified stepdown that could be tucked in the light housing.

Sounds like a good idea. However I'm not an electrician and fear that I would make a mess of it completely. So I stick with the battery. A quick turn to left, unscrew 3 small screws and replace the battery and set the clock. Takes less than 5 minutes and I can do that once a year without a problem, so in 10 years I am looking on less than 1 hour of work. If I would try to build something that would transform and fit into the housing it will take me many hours and most likely cost a lot more.

Nothing anymore involved than what you have already done. Just a couple of resistors with the setup basically being 12 volt source to 10KΩ resistor to 1.5KΩ resistor to ground, with jumper wire between the 2 resistors to feed the 1.5 Volt clock. Insulate everything and you would be good to go. Knowing what I do not, to keep it compact I would probably make the connections, run some good electrical tape around each individual component then put some thick heat shrink around everything. You could also just embed in electrical putty and electrical tape. (that's how I make "wet connections" with my low voltage outside lighting.) Google voltage divider circuit and you will see the formula and circuit. You would be surprised how simple it is.

The internet is unbelievable. I can not believe there are still people out there that are against getting smart phones and don't know how to turn on a home computer. I've been in meetings at work where someone is making stupid statements and I do a quick search with my phone under the table for the correct answer. It stopped people pretty quick from making statements as facts that they pulled out of their asses.

Reminds me of my formidable years when I had to get on a bike and ride 5 miles to the nearest library to study my current interest! As a child of a divorced laid off truck driver, we were pretty poor, and that Funk & Wagnall set of encyclopedia and the current year Almanac, and a few other reference books served as my window to the world. I couldn't imagine being a 12 year old again and having the instant access to everything we all do via our computers, phones, vehicles, TV's and other appliances!  That's one reason why for me I have the latest smartphones and smart TV's ...  It enriches my life exponentially and saves time, money, provides entertainment,  and connects me with others.... such as our 1963/64 Cadillac Website and Chapter members... just to keep this Cadillac related!!

Hey guys hope you’re having a great day. I have a question about the choke heater tube. Mine is loose at the intake and seems to be causing a vacuum leak. Any thoughts on how to seal this up?

New vehicle in the club

I was successful in getting a vehicle from the New York contact I talked about at the last club meeting. I am still trying to figure out how to post a picture of the vehicle that is tied with this comment so if you see a random picture of a black convertible in a yard, that's me haha.  …


Torque converter grab when idling in Drive

Posted by Cliff Johnston on June 14, 2021 at 8:47pm 2 Comments

Hi Everyone, been quite a while since i have been on here.

I have had an issue with the idle on my 64 Coupe Deville ever since i have had it.

With the Idle set high enough that it is smooth, but still a nice idle, the RPM seems only slightly too high for the stall of the Torque Converter. And therefore it tends to sit there and grab and lunge a bit. So until now, i have been putting the car in Neutral at the lights to stop this happening.

I've had the car dyno tuned and…


Can you help? Driveshaft Question....

Posted by Chris on May 30, 2021 at 8:55am 1 Comment


Newbie to the group here - we have already found tons of invaluable information on the board, so thanks! We are restoring a 1963 Series 62 Convertible. We are wondering if anyone knows of a source to buy the propellor yoke flange (that bolts to the pinion flange) for the driveshaft? One of our ears partially broke off. Not sure if we can buy just the yoke flange as an aftermarket part, or if it has to be rebuilt by a welder/fab guy? Maybe a salvage yard for a source? Again, any…


Thank you Kurt re: VIN location

I just wanted to say a thank you to Kurt for steering me to the tech tips page on V.I.N. locations.  Excellent information.  Thanks a bundle.
