I was in my 20's and unwittingly built myself a small bomb! There was no more than 2 or 3 drops of kerosene in that clock. I must have figured it wasn't enough to raise the mix to a combustible level. WRONG!  BTW, the clock ran for a couple of weeks after that, but once the kerosene completely evaporated, it quit again. | | | | Joined: Feb 2004 Posts: 5,975 Member/5000+posts! | Member/5000+posts!

Why anyone would want to go back to the original style is beyond me. Having said that I applaud those who try to keep everything just like it left the factory. They are real time machines. For me, function wins out over style points,on the otherhand, I have a military eight day that came out of an F-86 that just might fit where the electric clock is now. We shall see!!  | | | | Joined: Dec 2003 Posts: 14,797 Likes: 551 Member/10,000+ posts! | Member/10,000+ posts! Joined: Dec 2003 Posts: 14,797 Likes: 551 | I can't say for sure that all electric clocks work the same way but a couple of years ago I tore into a non functioning clock and was a little surprised to find that the clock is really a mechanical clock with the main spring replaced with a solenoid. About every 20 seconds the solenoid activates and winds a little "main Spring". The clock will tick tock for about a minute if the solenoid is not tickled. I've got one of those in my '68 Buick. Every minute or so I can hear a 'click!' as the clock winds itself. What's also surprising to me is that the act of setting the time on these mechanical ones also adjusts the speed of the clock. If the clock is running fast then turning the hands back will cause the clock to run a few seconds slower per hour. After setting the clock a couple of times, my Buick is pretty accurate - a month later and the time is still correct, not bad for a mechanical clock. Nowadays one can get the mechanical innards replaced with a quartz clock. Externally it looks the same, but internally it uses a quartz-crystal controlled electric motor. The result is incredible precision, no need for speed adjustment and no winding (so long as the electricity keeps flowing).

The Sporty's clock has that annoying "Not for certified aircraft, for EXPERIMENTAL aircraft only" disclaimer. The "FAA/PMA-approved" clocks are nearly $300. What a rip. | | | | Joined: Mar 2004 Posts: 12,760 Member/10,000+ posts! | Member/10,000+ posts! Joined: Mar 2004 Posts: 12,760 | David, Send MORE money!!! I didn't charge you enough.
