True Facts for Mechanics
"Given a 50/50 chance of assembling something correctly the first time, you will get it wrong 87% of the time."

I have an hydraulic thumb that I can swap between the forks and the bucket for my tractor.

Any time I have a removable hydraulic device, I plumb it with quick connects. When I do that, I "sex" the quick connects with a male on one hose and a female on the other so that when I attach it to the tractor, the Up/Down or In/Out on the control lever is always the same.

I stole the plumbing off the thumb for another project some time back, and of course now I need it so I ordered up the pieces and replumbed it.

Problem is, I don't remember which way I had the darn thing plumbed originally so I just randomly connected male to one and female to the other.

Haven't tried it yet, but the Smart Money says I got it bass-akwards.

87% with or without throwing out the directions before you start?.

87% after reading the directions. If you threw them out, it's 50/50.

Color code paint all yer sex parts.

Red for female, blue for male. (think about it...)

You won't have to worry about getting your sexes crossed, unless Ray Charles is working on yer stuff.*


Cuz Ray is both blind and dead. And that's double trouble.

I don't remember where I read this, but long time ago, I read that the original Murphy's Law was, "If a part can be installed incorrectly, somebody will do that." I think that it had something to do with a Human Factors Engineering study, connected to the U.S. Navy.

Newer interpretations of Murphy's Law say, "If something can go wrong ..."

Unless a car power steering gear has different threads to prevent this, it is possible to hook up the pressure and return lines backwards. Hilarity ensues.

Yep.
Most gear boxes have different fittings for high and low side, but people can and do splice hoses or use adapters to screw things up.

I'm not very mechanical, but I can tell you never try to ride a British scooter made in India. The controls are reversed. And it hurt.

"The people hate the lizards and the lizards rule the people."
"Odd," said Arthur, "I thought you said it was a democracy."
"I did," said Ford, "it is."
"So," said Arthur, hoping he wasn't sounding ridiculously obtuse, "why don't the people get rid of the lizards?"
"It honestly doesn't occur to them. They've all got the vote, so they all pretty much assume that the government they've voted in more or less approximates the government they want."
"You mean they actually vote for the lizards."
"Oh yes," said Ford with a shrug, "of course."
"But," said Arthur, going for the big one again, "why?"
"Because if they didn't vote for a lizard, then the wrong lizard might get in."
