So, when I go to play with the connections on an acetylene torch, I have
to mutter "tighten it off" or "loosen it on" as I'm turning to get it
right.

What do you do? Or are you just so mechanically inclined that you have
no trouble?

Just to confuse matters I have some RH threaded unions with the same
nicks that would usually be on LH ones. I don't know why they came that
way but I know from the application which way to unscrew them.

Just remember, flammable gasses threads are usually opposite to normal
threads, or do you have problems with normal right hand threads as well?

I can screw and unscrew bolts inside of blind spaces with my arm cranked
up like a pretzel. I never have a problem with right hand threads.

I think my problem is that I've got right hand threads so ingrained in my
brain that as soon as I think "loose" or "tight" I turn the thing the
correct direction -- for a right hand thread.

Interesting. I guess my problem is unique.

Nope..its very very common with most people. Most folks have so little
experience with lefthand threads that its rare and unique to most of
them.

About the most lefthand thread use that I can think of were lug nuts
on some older motor vehicles

http://www.carcraft.com/junkyardcraw...lefthand_lugs/

And of course..bicycle cranks....

So how many people actually learn to turn em?
Few.

The methodology of the left has always been:

1. Lie
2. Repeat the lie as many times as possible
3. Have as many people repeat the lie as often as possible
4. Eventually, the uninformed believe the lie
5. The lie will then be made into some form oflaw
6. Then everyone must conform to the lie

Tie rod ends on most vehicle have one RH one LH. Some fan clutches as
well. A few others still out there as well, usually in spots where a RH
thread would tend to loosen from the predominant torque direction, or
when a company wants to make it difficult for after market add-ons.

The light bulbs in New York City subway stations have left-hand threaded edison bases to discourage theft.

Bicycle pedals?
Lugnuts on older camper trailers?

I learned the hard way. Thick paint covered the Ls on the wheel studs
on the driver's side of the Army truck with a flat tire. I couldn't
loosen a lug nut so I enlisted a buddy about my not-so-large size to
help, and together we managed to turn it, the wrong way.

Then we sheepishly called on the motor pool mechanics to fix our
little oops. They were so impressed that we were strong enough to
strip the stud that they didn't give us any grief about replacing it.
Afterwards they treated us with respect instead of like geeky
electronic techs.

That, and they didn't want any more stripped studs to replace.

That depends a LOT on the gas, the tank type and size. Propane has at
least 5 different threads with both left and right hand threads.

I just look at the threads. And for the nick. And the color of the hose.

No trouble here. Fuel gasses = left hand thread.

"Right/left hand" threads means you use your right/left hand to show the
direction: curl your fingers & stick your thumb out - when the nut or
bolt turns in the direction your fingers are pointing, it moves axially
in the direction your thumb is pointing.

I hold my hand out a lot more than I used to - I seem to be getting
worse with age. I'm now forgetting what it took me so long to learn G.
