Bill Bryson At Home

Like all of Bryson's books this is interesting and witty.  He mentions that the 1889 Paris Exhibition that caused the Eiffel Tower has a competition for what to build.  The 900-foot guillotine was not the winner.  

And there is this marvelous one

Things That Make Sense for Governments to Do

It is an article of faith among some of the ideologically pure libertarians to argue that nothing the government does is legitimately their responsibility or that they add any value to our society.  While there is often merit to these criticisms there are items like this.

2/29/24 SciTech Daily reports on JPL's tracking of an asteroid that came with 1.8 million miles.  While not an immediate hazard, the prospect of a rock several hundred feel across getting close makes me glad that our government operates an office with a title straight out of a Star Trek episode: Planetary Defense Coordination Office.

Tripod Legs

I mentioned a design problem several weeks ago about how to keep the inner tripod legs from falling out the bottom of the outer legs.  There is enough disparity in the leg dimensions that it would not be a close enough fit to rely on friction.

One of you made a suggestion so elegantly simple that I have abandoned my attempts to machine an all carbon fiber solution.

The inner legs are 3/4" inside square and just a few hundredths inch thick wall.  The outer legs are 1.03" +- .02 inside.  I can buy 1/16" x 24" strips which I will epoxy onto the 3/4" square inner legs.  (This makes the inner leg very close to the inside inner dimension of the outer tube.  I can use thumbs screws at the bottom of the outer leg to lock the inner leg in position.

At the top of the inner leg I will drill a hole large enough for a nylon guitar string.  At the top of the outer leg, another where I will use a stainless steel SHCS to hold the other end of a 24" long guitar string (perhaps a little shorter to make sure the inner leg does not slide out).

The screw at the top of the outer leg is to simply removal of the inner leg for repair if needed.  Both legs will be cut at 60 degree angle to get a flat surface match.

I have also mastered the gCode for cutting circles.  If the legal historian work ever relents the first step will be cutting .875" holes in those 1" squares for the needle bearings.  The first attempt produced.872" holes so I may fiddle with the radius slightly until I get .875" ID.  Maybe start with the nominal .875" hole then adjust the radius .,005" until I hit the needed ID.

I also need a 4" OD disc on which the ears that hold the mount in various latitudes will be screwed as well as the slots into which the tripod legs will be mounted on a .5" axis.  This will be clearer when it transitions from the drawings in my mind to pieces of carbon fiber that I can photograph.

New House

There are 25 potential buyers already lined up for our current house.  It will not close before we close on the new house, so today was spent doing a mortgage application. 

The new house was described as having an XL conditioned crawlspace.  If you do not recognize "conditioned crawlspace," newer houses have crawlspaces that are cooled or heated and are pretty free of dirt and bugs.  This is much nicer if you have need to go under to do repairs.  Been there twice as a teen and do not want to repeat that.

What is XL?  It is about three or four feet of clearance.  A small ladder might be appropriate.  It would also make a tolerable expedient fallout shelter.  Two stories above you and a mass of basalt shielding (the foundation was poured on bedrock) you from the above ground side of the house that is the big radiation threat.  You might not want to spend all day there, but sleep would reduce your exposure quite a bit.

My House is For Sale!

Ideally there will be fist fights between buyers over who makes highest bid. :-)
