Big Difference!

Crimson King.  Autumn Blaze.

I identified Becky’s tree as a Crimson King Maple.  It’s not.  Crimson King is purple in the summer and yellow in the fall.

  Becky’s tree is an Autumn Blaze Maple.  Green in the summer, red in the fall.

Big difference.

I had a question about leverage and mechanical advantage

Who do I turn to with such a question?  McKee.  He’s a design engineer so we know he’s well versed.  He’s also a sculptor, so we know whatever solution he proposes is going to be elegant.  This is the guy who has a motto emblazoned over an elaborate oak and stained-glass hobbit door on his house that reads: “Never make anything simple and efficient if a way can be found to make it complex and wonderful.”

Our problem had to do with the couch/bed in the van.  There is a certain lack of logic to how it functions.  It’s primarily a jackknife couch, with an additional stationary piece on one end.  To convert from a couch to a bed is easy.  Lift up in the front edge of the couch seat and the parts (couch seat and couch back) separate and lay down flat for a bed.  To reconstitute the couch, however, is not quite so easy.  With the whole thing laid out flat, the leverage is gone.  There is not enough advantage to just lift the front of the couch seat and have everything pop back into place.  It takes more power than I possess.  The combined effort of Judy and me together, lifting from the front, can get it done, but that didn’t feel sustainable as a long-term solution.

I thought about this for weeks and came up with a couple solutions myself that should have helped, but they didn’t.  So, I turned to McKee.  “Leverage and mechanical advantage” he said.  “I can deal with that.”  We drove to his house.  I demonstrated the difficulty.  I got the couch part-way up and left it in that position so he could examine the mechanism.  He took a long look from every angle.  He muttered.  He disappeared to his garage and came back out with an improvised tool.  He directed me to the leverage point on the frame.  “Stick this in there and lift up here.”  I did.  The front of the bed lifted right up, and the rest was easy.  Exactly the power assist we needed.  And here it is, the elegant solution.

A four-foot long 2×4 board.  (Sanded and rounded so we won’t get splinters.)  Elegant in its simplicity.  Stows on the floor slid-in next to the bed.

The McKees.  Such good friends for so many years (50).

Our civic duty

We’re home and have voted, in our continuing effort to turn Texas purple.  That’s a tall order because Texas has been so red for so long.  The good news (for us) is that Texas has moved a couple points toward blue each of the last several election cycles.  The bad news for everyone is that since the races feel more contested this year, money has poured in, and political commercials have inundated our televisions.  Thankfully, we have mute buttons and fast forward to get us the rest of the way through.

Becky’s tree

That tree I’ve been sending all the pictures of over the last few months.

We’re not there in Colorado anymore, but Becky sent this photo.

Fall has fully arrived to this crimson king maple.

I’ve been thinking

We’re supposed to brush our teeth for two minutes, twice a day.  We’re also told that electric toothbrushes are maybe ten times more effective than a manual toothbrush alone.  Does that then mean that with an electric toothbrush we can brush our teeth for about twelve seconds each time and call it good?
