"historical chauvinism" is sometimes spelt "high licensing fees".


IIRC this was part of the problem in this case. I suspect that any patent
would have expired by now, but perhaps there is a surviving copyright.

Happy landings,

I had a yellow handled Snap-On that matched my aerobatic plane. However,
needed the Modine heater in the hangar replaced one day, and after the work
the screwdriver was missing.

Still not convinced that an electric is the way to go- it seems like they
chew up the head more than a manual. In the operating room we use mostly
hex sockets or torx head screws. Of course, a single bone screw can cost
close to $100.

The key, like another poster said, is the use of a real low clutch setting.
Simply put, the clutch slips at such a low torque setting, that there is not
enough power to tear up a head. Loosen the first little bit, and tighten
the last bit to the correct torque with a hand driver.

Some screws, not requiring high torque, can still be done without using the
hand screwdriver.

Have we covered Pozidrive versus Phillips? (Too many mgs to scan.)

Tektronix used Pozidrives exclusively when I was there.

Being a Canadian, I am also a big fan of the Roberson square screw and think

Look at the Wikipedia article
http://en.wikipedia.org/wiki/Robertson_screwdriver
According to it, Henry Ford wanted to use Robertson screws on Fords, but
Robertson had been screwed (sorry) by a previous licensee and refused to
license any other screw manufacturer to make them. Ford decided that he
wouldn't trust a single sourced screw, so went to something else. And
thus, Robertson missed his chance to have Robertson screws become very
common in the US.

From Wikipedia
http://en.wikipedia.org/wiki/Robertson_screwdriver
http://en.wikipedia.org/wiki/P.L._Robertson

I note that Robertson was having the same kind of legal problems protecting
his invention as the Wrights were having at the same time. Today we realize
that he would perhaps have been smarter to give away the license to use the
screws and to retain the license for the drivers.

What's your personal favorite tool? (Mine is the Snap on ratchet screw
driver. It has a great action and feel, and in fact we use their same
mechanism in the operating room for placing bone screws)

So, back to aviation- let's hear your responses!


It must be winter, there is little flying so we are reduced to talking
about screwing.

Funny - airline pilots talk about screwing all the time - regardless of the
season...

Reminds me of the joke about a bunch of young airline pilots and one old one
gathering at the bar after the day's flying is done.

"Hey, Cap'n," says one of the young ones to the old one. "When was the last
time you were in bed with a woman?"

The old timer removes his hat, squints upward for a moment. "1955," he says.

The young pilots laugh. "Geeze, that's a LONG time, isn't it, Cap'n?" says one.

The old-timer looks at him for a moment, then glances at his watch.

"Hell no, son, it's only 2215, now...."

A male pilot is a confused soul who talks about women when he's flying,
and about flying when he's with a woman.

In fact, it's surprising that any sort of hardware works. When it works, it
is just biding its time waiting for a more inconvenient time for it to fail.

Viperdoc asked
... how many screwdrivers does the average airplane owner own? ...

All the ones I have -- somewhere -- or only the ones I can find and actually
use?

Viperdoc wrote
I have concerns about using an electric screwdriver on my plane- don't
they chew up the heads?

I use power to remove access panel screws and have never had a problem
stripping their heads -- and they're stainless. I use manual to replace
them.
