1974 - 78 eldorado clock gear replacement

[_Cap_]

Been trying to restore one of these clocks for my car for the better part of 6 months, found that all of them i could find had one gear missing, a brown gear that acts as the main drive gear

TLDR found one in a clock and was able to measure it before it fell apart and made one

This model is made to be resin printed because it has to be at a small scale, should be scaled to roughly 6mm across

Nice.  Does the rest of the mechanism appear to be kinda gummy when you find them with these failed gears?   I'm just wondering that is a contributing factor to that gear failing.  This being the 'digital' clock I suppose there is quite a bit of stress on the hour where every drum has to turn so a constant loading and unloading of stress.

Others can answer but I would guess the same clock was used in all the models since dash was more or less the same even in the Seville.  Not sure when they went to a quartz movement or if that changed that gear setup.

sorry just now seeing this, i have a revised model i posed recently i think
but no, usually when i find the clocks they are in good condition and rarely anything gumming them up. I put some clock oil on all of the joins and gears to make them run smoothly and they all seem to run perfectly

As far as I've found, they switched to quartz in 79, but i could be wrong on that, i know that's when they changed the overall design of the clock
