Why do power drills have R and L?

Motorcyclist magazine did an excellent article in the early 1980's where they trashed the various steering myths. Keith Code did even better when he built his "No BS" demo bike. Youtube has videos showing it in action. Here's one example:

First the myths. These things don't work to quickly and accurately initiate a turn on a motorcycle:

- Putting all of your weight on one foot peg.

- Digging your knee into one side of the tank.

- Shifting your weight to one side.

None of those things will allow you to quickly and accurately steer a bike. What does work is countersteering, and the most efficient way to do it is to push on one handlebar - right to go right and left to go left. You can achieve mostly the same effect by pulling on the opposite bar, and indeed you'll have to do that if you're riding with one hand, but pushing is much more effective.

For more info, I recommend the book, "Proficient Motorcycling", by David L. Hough. He discusses cornering on pages 49-62.

Years ago I heard stories of tweens etc. who had never seen a dial phone. I wonder, if they were kidnapped and the only phone was a dial phone, how long it would take them to figure it out.

Interesting. I think my '50 Olds had left hand threads on the left side.

all the later cars, starting with a '65 pontiac, had right hand threads on both sides.

No it isn't. I think of the time of day as a position in my head. Afternoon is on the right, evening on the left. A quick glance at an analogue clock tells me it's "late afternoon".

I don't wonk why I wrote that.

Try a Renault or Fiat, they frequently go well above the middle.

I bet it was French.

I thought all cars made in the last two decades had variable electric water pumps, so the temperature should stay pretty much exact. Just as humans use brown fat cells to generate heat and variable blood to the skin surface for minor temperature changes, meaning we don't have to constantly sweat and shiver and look silly.

Were you imagining this?

Or a 4 wheel wagon with automotive type steering behind an offset 2 wheeled baler. Cut the corner too short and get hung up on a fence post - then try to get backed off the post far enough to be able to get the whole rig out and around without hanging up again ------. I learned that at 13. Driving a 540 Cockshutt without power steering and a clutch that took half my weight to disengage ---.

Must be a Limey thing. We went away from bolts to studs and nuts in the fifties and havent looked back Strip a hub by crossthreading the bolt and it costs you the complete hub (or axle). Crossthread a stud and you just knock it out and replace it.

Out Renault 12 had studs. My 1961 Mini had studs. The MGB has studs. The MG TD has studs. The Isetta has studs. The e-type had studs. So does the Type S jag. So did the TR7.

My '35 Chevy had studs, my '53 Coronet had bolts. My 67 Peugot had studs. My '57 Fargo had studs. My '38 Terraplane had bolts as did my '49 VW. I converted the coronet to studs so I could mount mags.

No, your 1998 Chevy did NOT have left hand threads.

Chevy didn't have left hand threads even back in the fifties. A few Pontiacs did in the fifties

You can appologize for being wrong. I was a mechanic for decades. Worked on Chevys and chryslers and toyotas and even the odd triumph. Rolls, Rover, and Moskovitch and just about anything in between.

By 1998 even Chrysler had LONG abandoned LH threaded wheel studs

Getting about 3 months to the gallon right now - ---

That often depends on if it is hot or cold too- - - --

I see you have never ridden a BICYCLE

My ratchet spanner is really annoying. Perhaps there's a mechanical reason it can't be done the other way, but I have to turn the knob on the head of it anti-clockwise to set it to tighten bolts. Very counter intuitive. I also wish they'd make the ratchet looser, because you can't use it to tighten a bolt which doesn't have much friction, you have to try to get your hand into the tight space to do the first bit for it.

I tend to think I remember it being set in one direction, then tighten something I'm trying to loosen, making it impossible to remove.

I've never found those to work, I just use a cobalt drill. I always use cobalt for metal and tungsten carbide for masonry. Anything else wears away.

My current car is s*it at that. The guage is also non-linear, and if it's relying on that then no wonder. It takes 3 times longer for the guage to go from full to half, than from half to empty.

But the average speed is very accurate, so I use it to confuse those stupid SPECS average speed cameras. If I'm stuck behind a lorry below the speed limit, I can go way over the speed limit until I pass the next camera.

In the UK, cheapest is just "supermarket". Anything form BP, Shell, Esso, etc is a ripoff.

Bullshit. I know a few morons that don't know their left from right, but everyone knows which way a clock rotates. What I have seen is their inability to know which way is clockwise if something is upside down - eg you're tightening a screw underneath something. How do these people survive?

The same kind of thing that happens when you look at a map, and then the real world. I used to know someone who said she can't read maps because when they taught it is school the map was on the wrong wall of the room, but most people don't seem to have that problem. I'm actually looking south at the moment, but that doesn't affect my ability to read a map an go somewhere.

Probably true, doesn't mean they associate it with the word "clockwise".

It's not that simple a process. It only SEEMS simple because you're used to it. Same with reading numerals.

I never got used to the idea of going through someone else's server just to do something locally (like looking at a clock 6 feet away).

Half past 8 (8:30)?

Also, I just looked at the clock here (3:07) and took even less time to figure out that it was a little after three. The whole thing was likely much quicker than saying "Hey Alexa, what time is it?"

Although I'd look at it, not ask one of those "voice assistants".

I do have one clock that speaks, which is useful in a dark room. This just requires one button press, not the slow and complex process of verbalizing which makes it harder to get back to sleep.

A lot fewer people are carrying watches now that they have mobile phones.

Note that with the fluid, turning it clockwise is tightening it like with screws.
