The Sounds of Night Shrouded the Forest
Ginny says our equipment business is the world's most expensive hobby.
I became involved in making equipment because I wanted to know how to
simplify and make it better. I've always enjoyed mechanical things and
in figuring out how they work. When I became a potter at the Los Angeles
County Art Institute, the equipment was non-existent and, therefore, it
was a fine opportunity to make wheels, mixers and kilns.
In my search for the underlying concepts
of equipment, it was necessary to let go of the way other people manufactured
them. Take electric wheels, for instance. When the alternating-current
variable-speed wheel that Pete used for years was taken off the market,
I had to investigate direct-current motors. I had to teach myself how
to convert electricity from alternating to direct current. I opted for
a then-recent development called transistors, an electronic technique
for converting voltage. But I wasn't happy with the results because it
never produced a nice smooth control of the motor, and tended to be noisy,
jerky, unpredictable and wore out quickly.
Then I hired an electrical engineer in Silicon
Valley to help me. His advice was to take a step backward in technology
and use a large variable transformer. The cost was high, but in the end
it would give a smoother, quieter performance, particularly at the slow
speeds, which, as all potters know, are more important in throwing than
fast speeds.
Another problem was the gear box. For years
we used gears to cut down the high speed of motors, but the gear boxes
began to vibrate and become noisy. I found this was due to a manufacturing
process. Whereas, formerly the gears were machined on a lathe, now they
were cast and then tumbled in a machine to knock off the rough edges.
That was fine for escalators and conveyer belts but not for potters' wheels.
So I changed the drive train to use V belts.
Since I wanted the quietest, most efficient,
most powerful equipment, I ended up using the variable transformer system.
It is the simplest because it only uses two components: a transformer
and a rectifier. Everything else is switches. We get more horsepower out
of the same motor because the direct current coming through the unit is
purer, resulting in a smoother performance.
I seldom recommend using more than a 1/6
horsepower motor, yet beginners frequently say they need a horse-and-a-half.
If I ask them to tell me what horsepower means, they don't really know;
it's just a number to them. Eventually, I found a way to rate wheels without
reference to horsepower or torque. I call it "centering capacity,"
refering to the number of pounds of clay one can center on the wheel before
the circuit breaker blows. Most potters can comprehend that. When I say
a motor has "50 pounds centering power," they don't have to
worry about what its horsepower is.
After a fire burned down our factory eleven years
ago, I chose to use the insurace money to redesign some of our equipment.
I decided to use a monolithic aluminum frame onto which everything would
hang- the legs, bearings, table, shaft and motor. I thought this would
be the ultimate type of wheel until one day in a restaurant I saw a baby
chair called "Sassy" that hung on the edge of the table. I said,
"Wow, if I did this to my wheel, we could make a "sassy wheel",
one that just hangs on the edge of a table." So I came up with what
I call the "Clamp-On Wheel." It's a perfect wheel for schools
and fairs, for the handicapped and for overseas shipment, because it can
be reduced to its elements and reassembled upon arrival. I have even carried
one with me on airplanes and put it in the overhead rack. Last fall, I
took one with me to Japan in a suitcase.
Originally, I envisioned a mixer as a giant mix-master
with a central beater. I pursued that idea for a long time, making various
unworkable Rube Goldberg contraptions. Finally, I put the whole thing
on the back burner and forgot it for a while. Then one day I woke up and
in a flash knew the solution to my problems: Instead of rotating the beater,
rotate the tub! Now we have a chain going around the tub that gives maximum
pull, as against the earlier idea of a little pulley down below trying
to rotate the beater.
The basic concept of the tub rotation has
not changed for twenty-five years. Cement continues, for a number of reasons,
to be the choice of material for the tub. First, it is non-rusting. Second,
it is heavy enough so its momentum will pull through stiff clay chunks.
But the serendipitous reason for using cement is because the clay will
not stick to a wet, porous surface, unlike a steel tub in which the clay
has to be scraped off. Another important change was the use of round bars
instead of sharp scraper bars to remove clay from the side wall. A phenomenon
called the "Conat effect" pulls the clay away from the tub,
making removal easier.
Early in our equipment business, I resisted advertising
our products. Sales came strictly from word-of-mouth. Ginny laid it on
the line. "We've either got to advertise and swim, or we will sink."
My reaction was, "OK, if we're going to advertise, let's enjoy it,
and I hope other people will, too." So instead of conventional high-pressure
ads, we always try to put some humor in them. I guess it has become our
image now.
Each month I try to think up an unusual angle. The most
recent one turned out to be one of our most popular. I was photographed
all dressed up as a young kid with a skateboard, standing on the corner,
with baggy pants and baseball cap reversed. Lots of people wrote and called
about that ad, particularly school kids who sent us pictures of themselves
all dressed up like that. I suppose the key to its success was the funny
seventy-three-year-old man acting like a kid.
Dawn Burst Over the Mountaintops
I suppose you could call me a classicist. I came out of a Judeo-Christian
background with a great appreciation for classical beauty in the Western
sense. Even though I have spent considerable time searching for beauty
in other directions, I feel that I am, after all, what I was born into
and raised with. It's difficult to eradicate all that!
Once I heard that Bob Arneson had said of
me: "It's too bad about Paul. His work is so beautiful that there's
not much possibility of his making a real contribution." Comments
like that or being around Pete with his massive, visceral handling of
the clay can give one an inferiority complex. But when I am able to distance
myself and look objectively at my work, I say to myself, Well, listen,
what you do is the thing you like to do, and there are reasons for that.
Maybe you can't be visceral, but you appreciate the organic qualities
of the clay, its plasticity, and how it takes imprints and texture. I
think it's important to find your own way.
You know, I'm still trying to figure out
what that little voice inside is. I often quote Abraham Maslow and his
theory of self-realization. He says that everyone in the world has certain
basic physical needs that have to be met. Initially, they are physical-food,
shelter, sex, love; reproduction. Once those needs are satisfied, there
are those among us who want more in life-perhaps watching TV, games, sports,
movies, etc. Then there are people who are not satisfied only with seeing
such things but want to play the sport, live the life, etc. And so on
up the ladder until the last group is reached, and there we find the artists,
musicians, poets and writers.
I hope my work will gain some recognition for
its uniqueness. Of course, I'm proud of the inventions I've made and my
contributions to machinery. In many ways I feel satisfied and fulfilled
by that, but I still want to try something new. That's why I've started
to make bronze vessels. It's beginning to pay off, although in terms of
money, I'd be a lot better off if I made bronze replicas of cowboys, Indians,
mermaids and cute children!
I've done the best I could with what I have. At
least, I hope my mother is satisfied that I have. I think I've pursued
just about everything I've wanted to pursue with all the physical and
mental energy at my command. I've never felt I couldn't do what interested
me. Pete once told me: "Listen, go ahead and show your work anytime
you're asked, even if it's at a county fair with the pigs and chickens.
Just make sure that it's your best work. Every time you're invited, accept
it, and show your best work." I've followed that advice.
And I've sure had fun with life!
