What a Man Can Do

What I saw a man do made me question the professed causes and benefits of the industrial revolution, the wholesale replacement of skilled craftsmen with autonomic machines. Many of you are familiar with todays industrial robots, metalworking machinery, the synthesis of the two, and their inherent precision capabilities. Consider how really specialized those devices are and how limited in what each can produce relative to programming and setup time. Now, consider this:

Y'all know I am a practicianer of the manly arts of Horseshoeing and Blacksmithing and if you are like I was, you're pretty sure the old ways of fashioning metal are fairly crude and imprecise. One of the tasks I was given to perform at horseshoeing school was to fashion a punch that would impress the exact precise shape of a certain type (there are many) of horseshoe nail head into an piece of red hot steel. I chose to make an "E" head punch for a #5 nail. An "E" head nail has roughly the shape listed as 'countersunk'.

I took measurements of angles, dimensions, used a caliper to measure the cross section of the shank, drew it up and roughed it out with hammer, fire, and anvil, then went to the grinder with my drawings and calipers and protractor to finish it up. Two hours later I was not satisfied. Disgusted I went to the head instructor and proprietor of the school and expressed my frustration.
- Let me see that.
I presented my work. He glanced at my handful of tools and drawings, smirked, arose from his desk and without a word went to the workshop to my anvil, started the forge and placed my work into it.

- What's this supposed to be.
JACIII - "E" five.
- OK. Watch.
He opened the forge door and removed the glowing steel. Placing it on the anvil at an angle, he spat into his palm, hefted my hammer and obliterated what I had so painstakingly wrought in three "Thor"-like blows. I stood in shock! Two hours of work gone, and this ham handed SOB squashed it in three blows and 5 seconds. Then...
He rotated the piece, so... WHAM! (full on hammer-stroke brought from above his head).. WHAM!WHAM!. Rotated it again, WHAM!.. WHAM!WHAM! .... eyballed it WHAM! fliped it over, spat. tap-tap-tap..tap, eyballed it rotated itWHAM!.... WHAM!

- See?

And departed the workshop. Total working time elapsed - less than 15 seconds.
I thought 'Bullshit!' and got out my measuring instruments. No bullshit. I tried the punch on a piece of steel and dropped a #5 E-head into it resulting cavity. perfect.

P E R F E C T

Not close, not good enough. perfect. As if you had used the nail itself to make a mold into playdoh and dropped the nail back into it.
"How can he do that?", you ask.
Answer - Because he is a master and student of an old-world craft and, most importantly, because nobody ever told him he couldn't. He has no formal education in modern methods of machining and is largely ignorant of and precision machinery beyond a common drill press.

The Monolithic Dome



I've always had a problem with these and Bill points to a valid concern about expansion causing cracks, but the stress that concerns me is from the temperature gradient from the outside surface to the inside surface of the concrete structure.

This is the primary mode of natural failure of most crystaline ware and it should also apply here. As the outside surface is warmed it wants to expand but the inside surface, being cooler resists that expansion. This places the outer surface in compression and the inner surface into tension. This is not a bad thing as it toughens the outer shell, but when the sun goes down the outside will be under tension which means it's lookin' for a flaw, stress riser, or any other excuse to crack. Given the thickness of the typical wall these forces could become quite large.

First Hand Report from France

Alex from the GPz e-mail list provided an unsolicited european account of the 'troubles' in france.

Here's the link for Alex' blog.

In case anybody of you is wondering about the ongoings in France: It's a
mess.

Two youths died after - presumably - fleeing the Police in Paris, for an
identity control. Now you can argue whether random identity controls are
abusive and wrong, but at least they are not worth to die for not being
subject to them.

This took place in the "village before the village", which is called
"banlieu" in French, for which "banned place" is the literal
translation. The inhabitants of those villages are to a part citizens
who came from the former French colonies or "areas of power". They are
legally French citizens, they speak the language, but for the last
decades (since ever they came over) they have been subject to discreet
and sometimes not-so-discreet negative discrimination. It's hard to find
a job if you live in the wrong area, have the wrong name and the wrong
look. The bit of that which I can feel is that you'd better prepare for
a control if you have a dark complexion and cross the borders. I see
this happening in front of me often enough.

Out of frustration some kids (we speak of youths, 11..15) started to put
cars to fire in Clichy in the night after the death of the two youths
and this was obviously a big show - since then, mostly kids all over the
country think that it's really big fun to set cars on fire and play hide
and seek with the Police. There is no coordination, no leader, no real
motivation except the "fun" of making riots happen - and apparently it's
very funny to even burn the very schools and kindergardens which
actually are in those areas, thus limiting chances for education and
integration even further.

Not to speak of the people whose cars were burning - these are not the
places where they sell a lot of all-risks-included insurances.

But politics are not sleeping and the French interior minister had
nothing better to do than to insult the people, thus pushing the riots
even further. And to announce that the police will act with "full
force". They do not, and it's a wise decision - any further dead people
on any side would start an avalanche.

In the meantime, local leaders and religious leaders, the parents of the
kids who died in the beginning, asked everyone to let things calm down.

This night, the first curfews are in place.

I'm living pretty much on the countryside, around 30 min away from the
next cities - there have been some events, but at least a few days ago
the Gendarmes (MP) were not upset. I'll see one of them tomorrow and
will know more (or not ;)).

cheers
Alex


Thanks for the heads up Alex. You stay safe in the countryside and shoot all trespassers like we do here.


It's a different world over there and Alex's view is going to be a bit different than ours. No flames toward Alex, please, as he has done us the favor of providing a firsthand account.

You gotta love the frogs:
"Fire and blood in France -- at least that's what some foreign media claim is going on," Le Parisien wrote. "Paris is burning, civil war, war zone, race riots -- the headlines, especially on TV, often have no nuance."

Nuance he says! You can't make shit like that up.They are running wild burning the place down and he's upset about the lack of nuance in headlines. Ha!

Tornado Defense

Photo credit to http://www.karinya.com

Bill asks:
What would it take to build a tornado proof house? I'm guessing the roof would be the tough part, but folks make houses that can take a cat 5 hurricane, why not tornado proof? As I type, I'm thinking that with a wind load of a few hundred pounds per square yard, and having to put up with airborne cows and such,

I have heard of aerated-concrete dome houses that are supposed to be able to take massive wind loads, but there is no telling where a load spike might locate on a structure or how massive the spike might be since we really don't seem to know that much about how the darned things function.

"Were you prepared for this?"


This was the question the CNN reporter asked the deputy fire chief in Newburg, Indiana. Like they had three days to prepare? Ditzy bitch. The Emergency Broadcast System failed as did the 911 system prior to the tornado. The government will take care of you. Don't you fret.

I reckon y'all have heard about this tornado in Southern Indiana and North-Western KY Saturday night. We put in a quick call to the inlaws this morning as MrsJAC has an aunt with a farm next to Ellis Park (the horse track that got hit. Bless 'em, their all OK. This country lets a twister run wild, as you can see.

Don on the GPz list just checked in and he's worried that he hasn't heard from his baby sister who lives in one of the areas hit. Prayers are appreciated on his behalf, and all those injured or suffering a loss.

Some of you boys out west may think the country in the linked pics looks familiar; It just goes on forever so flat a teaspoon of water will cover an acre. I miss it still and these rolling hills in central Kentucky make me feel plumb claustrophobic.


The work of one ugly critter.

I Miss My X-Car


For those of you not in the clique, an X-Car is common parlance among owners of the Ford Excursion. Just as fuel prices started to rise I ditched the Excursion in favor of the most fuel efficient 4x4 with 5000lb+ towing capacity I could find. We got a Jeep Liberty smoker (that's a diesel ladies - SB already knew that) and it is big fun, reliable, and cheap to keep. It's no Excursion, though.

I firmly believe there is no luxury greater than space. That being said, our old Excursion is probably the most luxurious vehicle I have ever been in, and it was quite reasonably priced for what it was. 8000 lbs of steel, 425 Hp and 400 ftlbs of torque, four wheel drive like an old power wagon, a foot of ground clearence, four cows worth of leather interior, drove like a big Mercedes, an undercarriage that brings to mind a cement truck.

I have had a sneaking suspicion that the fact that it and other SUV's offered unparalleled luxury and capapbility to the masses is the primary reason for the 'anti-SUV' vehemence in society. Who do you hear gripin' about 'em?! Beady-eyed-cocksuckers with enough money to buy 1000 of 'em. It's just no fun being a bigshot if when stopped in traffic the view from your limo is the polished hub of a 4x4 wheel on Suzy Homemaker's Suburban which happens to have features and amenities your limo doesn't. That won't do. Can't have folks who work for a livin' havin' it too good, can we?

The other SUV haters are commiesratbastards and can't abide having the benefits of the free market displayed before their unbelieving eyes.

Alas, what the beady-eye-cocksuckers and the commie-rat-bastards couldn't do fuel prices have. The X-Car was nice, but I couldn't see spendin' $300.00 a week to have the wife livin' large.
