Hi Vince,



I wrote a nice detailed reply to your post below...but I
never-heard-a-peep..!

So, I will make another reply, shorter this time, maybe...as I amble amid
the writ, below...

Thank you...

Oh no, it is entirely consistant in every way...with everything...with me, I
mean...

No...

I just note where the shit flys, or where it would fly, when there IS some
test or routine or intuition or past experience to have established 'where'
and how particles, debris, or sparks or whatever have some path they will
assume under some conditions...and I note 'why' they assume the paths they
do, and I do not put my Eyes "there" in their path.

It is very simple...

It is all exigencys, and, their ways...

And, it is a deference to them...or, at-once, to me as well...

Well. sure...

And, observe how things work...observe what things 'do'...when do they do
what they do? How do they do it...

What are we doing? How are we doing it? How do we pay attention? Are we
paying attention?

Are we imposing some rote or habit on something, are we intimitely involved
in some involvement or interaction? Or just partly 'there'?

Is the Machine, and the Materials between us and the Machine...are they yes
or no doing exactly what we are asking them to do in any given moment?

Far as I could ever tell, they always 'do' exactly what we are actually
asking them to do, in so far as our interaction with them is taken literally
by them...

What are we asking them to 'do'?




> Phil, I think I might have some idea of the "bad habits" you refer to.


The bad habits essentially involve impositions on Machines and Materials
which arise from complaisency, or forcing them...useing force instead of
understanding, or ignoreing them, or where only some aspects of the whole
are being recognised or acknowledged.


This is true with everything...for everyone, always...it is always of some
importance...


One can be driving with someone in that person's car, the person has a Radio
playing, they always have a radio playing...one slightly hears some tiny
sound of a light muffled 'ticking'...one faintly smells 'hot' Metal...one
asks them "Will you kindly turn that god damned Radio "OFF"...and they
do...one listens a few moments, one says "Pull over...I wanna check
something"...

And in that moment as they are pulling over, the Smog Pump's bearing locks
up fatally, the serpentine belt snaps, and the Power Steering Pump shaft
bent from the stress, and...

Meanwhile, 'you' ( unlike them) would have p-r-o-b-a-b-l-y scented/heard
this miles ago...and done something about it before the catostrophic
failure.

They have 'air bags'...why should they care?

I hate modern Cars anyway, but I have had things like this happen when I was
a passenger in them...

Lots of people drive...few pay attention to more than some few aspects of
what they are doing.




I never have my head or body in line with the Fan of a running Engine...

Many people lean over from the front to goose the throttle and rev it,
especially after doing a tune up or something.

I decided when I was like 14 or so I would never do this. I decided it from
seing others doing it and some of me thought "You know, some day, some Fab
Blade could be bent a little, fatizue from minute flexing in use, and work
harden 'there' at the root and when someone revs it, one way or another,
that Blade could fly let go..."

Then, over the years, one hears of situations where someone was leaning
over, or someone just standing to the side watching when someone else goosed
the throttle, and, rare as it is, sometimes the the Fan can shed a
blade...and someone gets it right trhough the face or side of the hear or in
the throat or wnatever...this does happen...

Easy to avoid...one does not stand in line "with" it...

Like that...in endless ways...everything...little things...everything...

Standing in line with the Grinding Wheel when one turns the Bench Grinder
"on" is a "Bad Habit"...and one in which safetyglasses will be little
consolation if the Wheel disintegrates just as it comes to or reaches speed.

Hair...from Irish Setter's long bushy Tails, a Girl Child with long hair
waling up to see what one is doing, a Z.Z.Top kinda Beard, or long haired
pal stopping by who leans over to pick up something off the ground next to
the Grinder whuile one is running it...

"Bad"...

Habits of circumspect...


But my question was - what are they/we/whomever doing? How are they doing
it, for there to be particles or whatever comeing "up" to threaten their
Eyes in the first place?

Not having examined 'this' and made sensible changes about it..."is"...a
'Bad Habit'...


I do not have any such particles comeing "up" when I am Grinding...

Why would others?

Again, a flying fragment from 'what'? As a matter of routine practice or
method?

From a disintegrating Wheel, failing catastrophically just AS it somes up
to, or has come up to speed?


I have recommended that one does not stand in the Wheel's line when the
Machine is turned on...and, that one let it come to Speed for a little bit
and stay there before one bnegins one's Grinding tasks...as well as top make
sure the path of a possible disintegration is clear of people and whatever
else...

I have recommended one not Grind with any force on the 'sides' of Grinding
Wheels...

I have recommended on understand 'what' one is doing...

To me, this the best 'Safety'...

This is all SO general also...

Grinding 'what'?

Grinding Berrylium? Grinding Plutonium? Grinding a Crystal Glase drib on the
base of Pot-Vase? Grinding a Cold Chisel?

Every kind of item has to it some possibly important or special potential
considerations.




And, the essence of my assertions, is that if one elects to wear Eye
protection or not, or, for only some occasions or situations, or for all of
them, one does so most happily when one also understands the rest of it as
much as reasonably possible.


I even outlined a general scheme for a "quiet" and effecient Pot Grinding
Machine one could make which would be totally free from particle or
disintegration scenarios as well as that it would make no airborne dusts...

It layed there like a dead fish...!


Lol...

Likely we were not really thinking of the same things in our imagined
scenarios.


Best wishes!

Thanks for the fun...
