Just need to vent...

Anti-ClockWise = CCW to us in non-Commonwealth countries. Lots of Canadians here, and lived / worked w/ them a bunch in WA, old habits die hard

 

Ah......time.
"Clocks" are interesting things.
I worked with scientists who insisted that hours, minutes, and seconds were only devised to make clocks more attractive....or 'convenient.'
It's the original "analogue versus digital" argument.
Degrees, minutes and seconds DO make for more convenient sea navigation in a 'pre-1800's' world.

Face it.
We live on a spinning ball.
People who are educated beyond their intelligence might describe it as a rapidly rotating oblated spheroid - but math is math and science is science.

On the afternoon of 10 December, 1941 this argument was settled for all.......um.......'time.'

It's COUNTER CLOCKWISE.
Deal with it.

People have ten fingers, but time and nature are analogue - NOT digital.

 

Depends on your viewpoint. Down at atomic / quantum / Planck scales, it goes back to digital, or at least partially so. With plenty of weirdness.

 

I think that's what I was getting at—if the twist is ACW, then it all comes down to flipping the switch on your reversible drill to ACW. The earlier post sounded as if how you secure it in the chuck had something to do with it, but I don't think it does.

 

I'm going to have to ponder that some.
You might have had me at the atomic scale and DNA seems digitaly but quantum seems like an a/d conversion, and then there's all of those pesky subs.

I would have to stand on the shoulders of those taller than myself to see that far.

 

Twelve stakes in the ground making a sundial may have been based on something other than aesthetics, but I have not read what that might have been.

 

I wrote above:

"If you look at the cut spring (brush on the other end)... and see ACW twist in it, secure in the drill chuck, and spin the brush ACW, so torque is trying to make the spring twists tighter. Spinning it CW tends unravel the spring in an unpredictable way, and can damage the hose you're cleaning (or you) rather spectacularly."

Specifically, 'secure in the drill chuck, and spin the brush ACW', is just getting it tightened in the chuck, and switching the direction switch according to whatever way you saw the spring twist, at the cut. In this case, ACW...

Earlier I'd written:

"Pro tip: make sure when you cut the spring, take note of which way your spring twists (CW or ACW). You want to secure it in the chuck, so the drill rotates the brush in the direction of spring twist."

Which is basically the same thing.

Main thing to take away, is not to spin this spring-mounted bottle brush in a direction opposite spring twist, when pushing into that main hose -- bad, expensive things can happen (and have to my hands)

I have. ACW's still used worldwide, and just as valid... so *shrugs*. Google can get people familiar w/ conventions that aren't theirs
