The Second Clock: A Craft-Altered Ansonia Derby

Since I was making good progress on my first clock, I decided to haunt the antique malls looking for a second one to repair. I wasn’t really planning to buy a clock until I’d finished the first, but I found the perfect second clock to work on.

I found it in an antique mall in Hillsboro (Oregon). It’s a mantel clock – a Kitchen Clock – similar to my family Seth Thomas clock that is my eventual target for repair (once I know what I’m doing). It also fit the bill of a) not working well, and b) not worth a lot.

Clock Repair 101: Making Sense of the Time Gears

In my previous post I finished cleaning my Goodwill clock, ending up with a jumble of gears and other parts. You may recall that when I disassembled this clock, parts sort of fell out willy-nilly, leaving me a bit fuzzy about what gears go where. In this post, I figure out which gears are part of the Going (time) Train (gear set), and as a bonus I calculate the length of pendulum this clock requires.

Clock Repair 101: I Finished “Cleaning” the Clock

In my previous post I showed the early results of my cleaning of my Goodwill clock by hand. In this post I show why cleaning by hand isn’t really very effective at removing old oil and dirt.

After a few hours of scrubbing parts with SOS pads and toothbrushes, then rinsing in water – twice to get all the soap scum off – then rinsing in alcohol (wearing gloves this time), the clock parts are all “clean”.

Clock Repair 101: a Time Bomb Waiting to Go Off

In my previous post I explained how I got started on this strange path to clock repair. In this post I talk about the dangers, some videos, and my first clock repair tools.

The first thing I did was to remove my Goodwill clock’s movement from the case. This step is pretty easy: unscrew the nut holding the hands on, gently pull the hands off, unscrew the wood screws holding the face onto the clock and voila, there is the movement.

Clock Repair 101: “Lasciate ogne speranza, voi ch’intrate”

The Dark Arts of clock repair open before me. I feel the need to wear flannel. …to create a basement workshop. …and to live where it snows most of the year. What brought this malady on? A clock.

I have an old Seth Thomas “Chicago” series mantel clock that I believe belonged to my paternal grandparents, who were married in 1909. I haven’t run it for years, and got it into my head that it needed repair.

Printing replacement parts for your Prusa 3D printer

I recently bought and assembled a Prusa i3 MK3 kit, and decided to prepare for printing emergencies by printing a full set of replacement parts as soon as the printer was working well.

I’d found, in using my other printer, that even high-quality printed parts do eventually delaminate under stress: after two years, that printer’s X and Y idler supports developed fractures. Because I couldn’t print the replacement parts (and because doing the replacement seemed daunting at the time), I wound up sending that printer to the factory for repairs.

I’ve also seen notes and videos from people recommending a set of replacement parts as a backup, in case you break a part while adjusting or doing maintenance on your printer. Having replacement parts on hand is also a good preparation for helping a 3D printing friend when their printer breaks.
