90 minutes to go 5 miles...

 

(Not my picture, I hotlinked.  Phone was playing Iron Maiden)

When I drove past it, the burnt out shell of a trailer was still there, they had earthmover equipment on site, and they were putting up a new sign pole assembly where that one for route 83 apparently used to be.

 

I knew it was going to be a fun drive home when the signboard just north of Columbus with estimated time to I-76, maybe I-80 (about 10-20mi north of rt 83) just said "- -".  Never saw that before.

I thought the whole thing with Japanese sword making, and the years of practice a person needed to become proficient in their use, was because they did not have access to any decent ores, so they had to improvise with variable metallurgy like coating the blade with different thicknesses of clay to control how quickly it cooled, and then spend years training people how to use the sword without shattering it because in the end it's still amazingly brittle except if used exactly the right way.

 

Do not get me wrong, it is mind boggling what knowledge and technique there is involved.  All the same, you could probably whip up a better sword in a day or two with an old truck spring.  Not nearly as romantic smiley

I understood the blacksmith was a priest, chanting and praying kept from rushing it.  The metal is folded on to itself over 400 times, if it's folded in the same direction every time you get the straight linear grain lines, random flipping gives the other designs.

In WWII, American GIs would snap the handle off and bring it home.  Under the leather and wrapping is engraved the family history of the blade; maker, owner, people it killed etc.  Nice but to me the blade is more interesting.  Look into an apprenticeship, it's a career!!

Aviation art tends to be technical and controlling. Watercolors are anamorphic and wild. Combining the two should have been a nightmare. Mom commissioned me to do a painting for Dave. Dave is a retired Air Force wrench. Dave also likes tigers. He also knows about the  A.V.G.

This might be my finest watercolor to date.

One of my favorite photos. I know jack-all about sail boats, but I do know the amount of precision and skill it took to get to this moment in time was amazing.

It's probably not quite the balancing act it seems to be.  It's certainly more so than a keel hulled boat (below), which as the boat heels (leans), the resistance to heeling increases as the keel becomes less vertical.  In a catamaran, the anti heeling torque actually decreases as it heals, reaching zero at 90 degrees (essentially capsized).

The most important controlling factor though is the angle of the wind, which is always directly parallel to the surface of the water.  That wind acts on the sail, creates torque, which makes the boat heel.  As the boat heels, the angle it hits the sail increases, and thus the torque decreases.  Because of that, it's essentially impossible for a keeled boat to be capsized by the wind (heeling torque goes to zero as anti-heeling torque goes to maximum just before capsizing).

So, it is still a bit of a balancing act, but baring sudden wind gusts, or change in angle (e.g. turning more broadside to the wind), being blown over is not has easy as it seems in a catamaran.

Why heel you ask?  Well, in a keeled boat, it can't be avoided, and it would be ideal if you could (capturing more wind, need less sail etc).  In a catamaran, it's pretty obvious by a picture of one up on one pontoon, far less hull drag.

Oh, and catamarans do have another advantage....

The B29 was insanely complicated and sophisticated for it's time.  It was also insanely expensive to design and produce.  The Manhattan Project (atomic bomb) was 1.9 billion at the time..... the B29 was 3 billion!  (Includes almost 4000 built of course).  It was the most expensive weapons program of WWII.

Here is the mechanism (targeting computer etc) for just one turret:

That is an insane amount of torque for a car that light and short. I wonder if it can pull the front tires when it launches?
