WARNING: I don’t know what I’m doing!
On a whim I bought a rusty, Ace brand 3 1/2″ (say 89 mm) vise at a garage sale. I’ve watched a few vise restoration videos, so I think I have a chance at restoring it…
How it started: I’ve been watching a lot of Matthew Read’s excellent clock repair videos (Open Clock Club Archive, How to repair pendulum clocks, and How to Repair Pendulum Clocks – LIVESTREAM). Lately he’s been repairing an early 19th century clock, doing a lot of metalworking in the process. Inspired by that work – and needed a vise for my clockmaker’s bench – I decided to buy a rusty vise and attempt to restore it. This post covers the first step in that restoration.

In converting a desk into a clockmaker’s bench, I wound up buying a router and router table to make the drawers. The router table has been taking up space on my workbench ever since.
I decided to make a rolling cabinet to mount the router table to, using scrap plywood and some drawers left over from a bathroom remodel.

The project is a good example of a thrown-together wood project, and a few lessons in “measure twice; cut once”.
My Ansonia kitchen clock had a loose warning pin – the pin that stops the clock’s gonging at the right time – so I decided to bite the bullet and do my very first actual metalworking, no-going-back, clock repair!

In an earlier post I calculated the ideal pendulum period for the Korean clock by counting its wheels’ teeth (outer teeth) and pinions (inner teeth). This post is an update based on the errors I made while attempting to do the same for my second clock: the Ansonia kitchen clock.
What follows is a more detailed “how to” for calculating the pendulum period based on gear ratios.

I just now learned how the great wheels – the mainspring gears – work, by finding they didn’t work correctly in my Korean clock. The strike train Tension Washer, that is supposed to hold the gear firmly against the ratchet, has come loose. …so I had to disassemble the clock, after it had run fine for over 11 days.

In my previous post about this clock I ordered a replacement pendulum suspension rod and bob, because the originals were missing. In this post I cut the suspension rod to length and adjust the speed of the clock, using audio recording to measure the timing of the tick-tock.

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.

In my previous post I calculated the theoretical length of the pendulum my Korean 30-day clock requires. You may recall that the clock as I bought it had a broken pendulum suspension spring, and the pendulum parts – the suspension rod and bob – were missing. In this post I order replacement pendulum parts.

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.

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.
