Furnace Filters and No Manufacturing for You

In yesterday's post I forgot to mention the other thing we did yesterday.  We replaced the HVAC filters.  I first discussed this here.  Yesterday I was really hoping to video the filters levitating into position, but both my hands were required.  The force of negative pressure is a wonderful thing when it's running.  The key learning yesterday was to have the rubber mallet at hand.  When the grate swings up, it does not always go precisely where it needs to be, encouragement is required.

Here they are, nothing is supporting their weight.  Jim reports that the filters lift off his hand about 8 inches out from the air return.  So, have the mallet ready.


Why manufacturing is not coming back to the US.  Go here and read this.  It was illuminating. Angus linked to it on his post.  It's long, but interesting.

Or, you could go here, and learn about the first women programmers who programmed the ENIAC computer before there were keyboards.

  1. Very good article. Too bad nobody in the trump administration has read it.

  2. I didn't read the entire article, but I agree he's provided very rationale reasons for the failure of the tariffs. One line that struck me related to the fact that you'll be electing a new president before manufacturing could be ramped up in the USA. And the fact, that most people wouldn't be willing to do the kind of work required. We see this here in Canada, with jobs in the service industry, which are generally low-paying, poorly protected jobs. Canadians complain about immigrants taking these jobs but in general, most wouldn't take one of those jobs.

  3. The A/C filters at my family home in Florida used to do that too -- lift off our fingers right into the gap designed for them! No mallets required as far as I can remember.
