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

 

Basically, almost, if you already know what you meant. The key thing is, if the twist is ACW, you'd better be chucking it into a drill that can run ACW—otherwise there just isn't any way to secure it in the chuck, so the drill rotates the brush in the direction of spring twist.

How you secure it in the chuck doesn't affect that.

 

That dump truck driver will likely be in his own set of PTSD

 

Good, I'm not the only one who always thinks that with a headline like that.

"Man dies after being run over with dump truck" would be ok, if it wasn't instant.

 

This is getting into semantics now

I haven't seen a single example of a drill I'd actually use to clean a CPAP hose with, and/or wasn't some antique, that 1) can't run ACW, or 2) doesn't lock in place when off-trigger, to fasten a hand-twisted chuck fixing mechanism.

My cordless 20V Dewalt has both. That's what was used to form the basis of the proc DeWalt's a pretty good example of a typical common drill brand; if you're gonna use a WWII-era one your grandfather passed down to you to clean your CPAP hose... then okay, eyes front

 

Well there were a few fractions of a second whilst getting run over that he wasn't dead yet, I suppose

 

I always love when people say "this is getting into semantics" as if that's a bad thing, when 'semantics' is the meaning of what's said.

 

The neighbor's tree (Ash) & the accursed helicopter seeds that every year during autumn, coat the rain gutters, the upper deck, the lower porch, most of the front yard ('till there's more brown visible than green), & the front porch.

 

Be grateful you still have ash trees.

 

Right. So grateful - I can't wait till next fall where I get to start Leaf blowing gutters & raking again.



At least the helicopter seed pods on Maple trees will yield sap good for syrup. Big fan of any tree that yields a consumable harvest. All these are good for is blocking up the storm drains. Louisville Slugger can just as easily make baseball bats out of birch or maple.

 

That’s what happens when you have to learn two languages.
