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.
Score so far: Vise: 1, Me: 0. In this post I tell the sad tale of trying to extract the jaw face screws that are frozen with rust – nothing has worked for me.
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.
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…
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.
As I said in my previous post about the Ansonia Derby clock, it seems that long ago part of the upper gingerbread broke and the owner sawed off the rest, reducing the upper gingerbread to a simple arch. I’d like to create new gingerbread for this clock. To do that I need to unglue the original, cut remnant and glue my to-be-designed gingerbread in its place.
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 I had set the pendulum length, regulated (adjusted the speed of) the clock, and set it running for a 30-day test, to see whether its springs still run the clock for its full 31 days. If they don’t I’ll need to replace the springs.
