It’s sad. My grandfather clock was an hour fast per day. When it broke down, it was correct twice a day (old joke). I suddenly had a very expensive paperweight in my living room (true life). That would never do. I had turned a working clock into trash. eBay! The replacement part retailed for $649. No!! I did not pay a fraction for the used works. Auction, bidding, success! (Long story short) $10.50 and postage was paid by the seller!
It did not fit. “Shit!” Oh, well, despair again! (Hey! I’m trying to fit a long story into a paragraph or two.) Old adage – in brain surgery – “if it doesn’t fit, …force it.” At the end an extra screw is not what you want to be seeing. I bet that makes you happy you asked? Nope, I finally used the auction part to tell me where all the gears went and in what order. Voila! Yes!! Really!!! I fit all those pieces and gears back in and I got it to work. It needs fine tuning. And in the course of things I found out why the clock doesn’t work right in the first place. Unfortunately, there was a piece broken before I ever messed with it. But now I’m ok to take a Kieninger clockwork apart. I can reassemble it with a little help. It’s mechanical. No jewels. No quartz. No springs. Hey, it’s not brain surgery!
