Zev, I am so glad you have perfect control and never make a mistake
in how you hold the items you polish in your gloved hands.
But most of us humans occasionally make mistakes and if we do so
when wearing gloves while polishing we lose fingers or experience
other serious problems. That is the issue not whether you can get
away with it some or most of the time. I have no doubt that a skilled
polisher can wear gloves with a lower risk than the average person
but that does not mean there is no risk. If you wish to make that
gamble then fine but to suggest wearing them on an open forum is
irresponsible.
I don’t know Jeff, a foot peddle can be useful, it’s an instant off
option, and possibly could allow the addition of a variable speed to
a polishing lathe… could be handy, so I’ll think about it.
It’s sort of like a flexishaft, there are a lot of things you can do
with a flexishaft that would be less convenient then if it was a
simple on off.
We’ve got to face it, we work with power tools, and inherrently they
can be dangerous if you don’t pay attention… just like a car.
Thank you, Thank you! Perfectly stated, as I have tried to numerous
times in past posts, but I don’t think it will help in anyway. Some
people just won’t or can’t get the concept. By the way, I think I
have bought supplies from you on E-bay. Are you the same Guy? If so,
Thanks again!

It has been a while since I last walked on the side of a highway,
one amusement was figuring in my head how fast the cars were going in
feet per sec. The number 80 comes to mind, a 6" buff goes about the
same speed. more back of the brain number crunching so you can doubt
my accuracy. I might even be off by an order of magnitude but even
then it is still going to hurt like hell or far worse.
Don’t forget inertia, there is no instant off, even my flex shaft
takes a while to spin down.
...the large leather gloves I use protect me from the heat and are
necessary.
Zev, your statement inspired me to say, as I have in the past, that
really heavy leather gloves work like a charm. Get the kind that
will stand upright on their own, with the cuff as a base. Maybe if I
made tiny jewelry pieces, such gloves wouldn’t work, but I make
larger pieces of jewelry, and these heavy gloves have been great for
almost 30 years.
What is really not optional is the plastic face shield. Sometimes my
jewelry piece gets snatched by the wheel, but never my gloves. Just
my experience.
Hoi All! The foot pedal / Kill switch is not there to prevent
accidents! Its only there to prevent more damage!
When something happens and the hand you normally use to turn of the
buffer is being eaten by it (The Buffer),that’s what the pedal is
for! A foot switch is only a additional safety, when, not if,
something happens! Thanks David and JeffD! I didn’t make myself clear
in my last post, sorry! Kiffer
all gloves, including tight gloves, have cuffs and cuffs are leading
edges. Leading edges snag. Trying to eliminate snags is a good thing.
Goes along with Murphy’s Law.

True, there’s inertia, but once the power’s off, there’s no motor
forcing the wheel through your flesh, so there will be less damage
in the instance of a catch and grab.
I suppose a breaking system when the power is off could be
improvised, I like this system :-
There’s always room in a manufacturing industry for safety
innovations.
I use my inverted drill like this all the time and find it
enormously useful. My question is, does anyone know where such
drill mounts can be purchased? Sometimes my students ask.
Sorry I am so late to respond. I just saw this in a catalog. I don’t
know anything about the quality, etc.
I guess the inertia/momentum can be 10-30 revolutions after the
power is cut. The first few revolutions will be full power quickly
diminishing depending on the mass of the armature and other rotating
parts.
The human reaction is rated at 0.2 of a second or thereabouts. How
many revolutions under full power is that?
A flex shaft has less momentum but it has more RPM. A polishing
motor has more momentum and less RPM.
Work it out and the answer will surely be…you will cut the power
after the damage is done even if there is a ‘dead man’ switch. There
is no fail-safe other than to be very aware of what can happen and
act accordingly.
