Adding an Air Filter to a Box Fan

During the wildfires of 2020 I saw many instructions for how to quickly duct-tape air filters to a box fan, to remove smoke from household air. Years before that I was interested in buying a woodworking shop air filter that would remove fine sawdust that otherwise floats in the air for days or weeks.

This post describes my experience making a air-filter-box-fan design, using 3D printed clips instead of duct tape to hold the filter to the fan.

CAUTION: I have no idea how safe it is to clamp an air filter to a box fan. Such a filter may reduce the air flow to the fan’s motor, which might result in overheating and fire. Always supervise the running fan. You’re responsible for your own safety.

Removing Rust and Paint from the Vise

I wasn’t happy with how much rust remained after the vinegar treatment, so I decided to give the vise a treatment with Evapo-Rust – my favorite rust remover.

I also decided that so little paint was left, I’d strip the remaining paint off, either with paint stripper or a wire wheel, depending on whether the paint had lead in it.

Restoring a Rusty Vise – it Begins

WARNING: I don’t know what I’m doing!

On a whim I bought a rusty, Ace brand 3 1/2″ (say 90 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 needing 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.

Building a Cuckoo Clock Test Stand

The family cuckoo clock I’m working on is being capricious about when it decides to play the music, so I’ve built a test stand that will let me see what’s going wrong.

After looking through the wide variety of weight-driven clock test stands on NAWCC.org. I decided to build a floor-standing U-frame.

Cleaning and Adjusting a Cuckoo Clock’s Musical Movement

I’m in the process of cleaning and repairing a family musical cuckoo clock. I’ve watched a lot of videos on repairing cuckoo clocks, and have disassembled, cleaned, and repaired one cuckoo movement, so I think I’m as prepared as I can be for working on the clock movement.

The musical movement is another matter. What follows is a detailed How To that captures what I learned, what to do, and what not to do.

Is That Cuckoo a 1-Day Clock, or an 8-Day Clock?

Because of the economics of cuckoo clock repair, you can easily find old, dirty cuckoo clock movements on eBay for a fraction of what a new movement costs. These movements come with no documentation, so you get to work out which chains, weights, and bellows (cuckoo whistles) are right for them.

In this post I calculate the run time (1 day vs. 8 day) of a cuckoo movement I recently bought, and the Links Per Foot of the chain it uses. These two numbers tell me what parts to buy to make a clock case for this movement.
