Hi Vince, all...



Lol...

Probably, "yes", this would benifit to have some explaination or
expansion...


Grinding Pots - glaze dribs on feet outsides and so on -

I would say for me or anyone, for "this", definitely DO wear an adequate
Breathing Mask
or filter, no
matter what the Abrasive System or device or method is...if it is Abrasive
and
high
speed and done 'dry' then wear a Mask...so one is not breating in swirling
fine dusts from this type of Silica laden
material...

And or
better yet, set up an outfit so the Grinding is done with replenishing
Liquid
Coolant...Soapy Water is fine, and this then carries off the particles,
aside from what ever atomization the mists may carry close to the Wheel or
Abrasive Belt. If these seem likely to be aspirated, then wear a Breathing
filter or filter mask so you do not breathe them in.

It is easy to make a Gravity Feed set up with a Five Gallon Jug or Container
and some clear soft plastic hose and a little petcock and a home made fine
oriface Nozzle even...so the Nozzle mounts or stays where one wants it...fit
it to a simple spring Clamp or as may be...

I have never Ground anything on a Pot to know how I would feel about the
rest of it...

A lot depends on where one stands, how one stands, and how one does what one
is doing...with anything...


Probably, if I was having to Grind Pots, I would get a large Carborundom
Wheel of fine Grit...maybe a 14 or 16 inch diameter, by 1-1/2 or 2 inch
width...mount it in some old Universal Mandril, run it at a rather slow RPM
( 400...or 600 rpm or something or see by experiment where I like it, ) and
have a Gravity feed Coolant dribbled or 'peeing' to where one wants it via a
little Nozzle that clamps however so, and a trough to catch the slurry and
so on...and NOT be doing it on a conventional 3,500 RPM, cramped, awkward
for 'this', Bench Grinder make-do.

No atomized mists containing Silica, no mess, no "DANGERS!!!!!", no
hysteria, no freak outs, no trauma, no de-scalping scenarios, no punched
foreheads, no revisiting of all the usual introjecting second hand trauma
freak outs, and "quiet" operations, too...just a nice easy "hsssssssss" of
the Wheel...


Can you, or anyone else here imagine a more Happy scenario, or a 'Safer'
one, for Grinding Pots, than 'that'?

I can not...!


I would say that "THAT" system or method then, would be my Heartfelt
recommendation for anyone who wishes to Grind on their Pots...and it is what
I would do if I had Pots to Grind.








Grinding general whatevers on the Pedestal or Bench Grinder -

What is the concern?

I have ground-sharpened, modified the ends of, reduced partial diameters
to make step-drills of, and whatever el;se on or with a great many sizes of
Machinists Twist
Drill Bits, other things on Spade Bits, made other end geometrys on them for
special purpose
things, done Grinding in
various ways on endless pieces of mild or other Steel, Brass, Aluminum
Alloy, Castings, making parts for
things, fixing things, endless
whatevers, and never once, ever, in any kind of way did anything ever get
into my 'Eye'...at least not that I can remember. Or, if anything did get
into my Eye it was not worth remembering, and made no impression on me for
me TO remember it.


Similarly, on the 6 X 48 Stationary Belt Sander which I have always used a
great deal for coarse work or surfacing things and shaping and other varied
aims...Wood and Metal...( mine being always in the
upright position, ) I once in a while on that one, get some little particle
of Brass or Steel into my Eye...same as I once in a great while do on the
Metal Cutting Band Saw. Depending on 'how' the particle 'feels', I blink
gently a
few times, the particle moves to the
corner of my Eye, I wipe it with my dirty sleeve, or finger, and it is
"done", I am
fine and that us all there is to it.

I squint a good deal too in many operations, it is instinctual now or always
was anyway...95 percent of what MIGHT have hit my Eye, which is next to
nothing already, hits my Eye lid and
does nothing.

Maybe, twice or three times in all these years, I walked to the Bathroom,
twisted the end
of a little piece of Toilet Paper, wet the end in my mouth, pulled up my Eye
lid, touched the twisted
'end' to the Metal sliver or particle and lifted it out from where it had
been under my Eye lid, tears streaming. And all was well.

One does well to have the discipline
NOT to 'blink'
when not-to-do-so is the appropriate response ( just like not to 'sneeze' if
that is the thing NOT to do) ...if one has some nasty little
thing
under one's Eye lid...or one DID blink at least once to get it "there"! -
and...that was all there was to
it..."done" and back to Work.


Someone else of different fore-thought or response might blink a lot without
thinking, rub
their Eye hard, rub some more, scratch the living shit out of their Cornea
for some possibly long term damage or making the particle or sliver actualy
embed even, start freaking out, stomp around in pain and exhasperation,
go to an 'emergency
room', wait five hours of misery amid third world wheezing and other's
sundry
exuperating sores weeping shiney streaks on the bench seats arm-rests and so
on, to
see some
schmucky overworked hack of a doc who maybe barely speaks bad english
anyway, finally, and, the doc lifts the Eye
Lid, gets the particle "out" and the poor victim gets to spend four thousand
dollars for the role and priveldege...and maybe gets some sort of illness or
infection FROM the visit. One of the new TBs maybe...


Okay...

So...how is it then that others claim to have so many troubles?


What are they doing? How are they doing it? What is the "difference" then
between doing things with no troubles? and, doing the ostensible 'same'
things WITH troubles?

Clearly...something IS different...

And THIS is ever so much more the matter, to my mind, than rote perfunctory
insistances which take into account nothing but that some people are going
to make problems because they do not know how to do something...do not
understand things, and react emotionally to the problems they make or cause
or make worse, by reacting to them.




Now, I never have anything come "up" toward my Eyes or Face when I am
operating a Bench Grinder, nor do I see or find anything in the way of
particles deflecting on anything to go 'up' from glanceing on my
clothing or legs or whatever, so I do not understand how others are having
particles comeing "up" to where they require Face-Protection??

When I am Grinding with the Bench Grinder, the Wheel is turning 'down' and
away from me and
whatever
sparks, particles and so on all go "down"...so...

On other people's Grinders, do the dusts, sparks and particles somehow go
"up"?

Are they running the Motors 'backwards????


Lol...

Anyway...

So...

I dunno...

What are the troubles people are having..and, how is it they are having
them?

Would be my question...and, would be what needs to be examined here...what
is the praxis?


In another decade we will be tirelessly admonished in shown in print media
adds and elsewhere, to wear 'Moon Suits' if we want to Bake a Cake.

After all, one might have "Flour Allergies", one might poke themselves IN
THE EYE with a Wooden Spoon..! One might infect others who wish to sample
the raw Batter, with some obscure communicable disease, because they were
drooling into it AS they stirred. One might harm their hand hitting the
Mixing Bowl sides when stirring...One might drop the Mixing Bowl on their
Foot...and THEN slip and fall on the Batter that had splattered...and hit
their Head on the floor...and...and...and Sue "General Mills" for not having
multilingual cartoon drawing captions on the Bag of Flour, showing them,
telling them, they MUST wear "protection"...oh not JUST for their "own" sake
of course, but for the sake of others! It will even be a "Crime" not to...

You just wait!

THAT is 'where' it is headed...that, and worse...


Sheeeeeeesh!

Love!

Best wishes!
