This is the Millenium and most of you are still talking about horsepower
and speed. How many of you truly understand that technology has improved,
even for a "Potters Wheel".
Do you understand the functions of a PWM or a PCM ? Do you know the
difference between AC and DC motor?
All of the pottery wheels use a DC Motor with a DC Controller. We have
tested them all and have found an inherent flaw in the controllers.
Voltage peaks out as high as 149 volts. This problem shortens motor life.
It's very easy to understand when explained. When you put more voltage in
the motor than specified,you shorten the life. i.e. 5-year warranty from
Clay Boss. Also, because the pulse is regulating voltage when a potter
sits at a machine and slows it downs, there is also a power reduction.
Less voltage to motor thru controller. Again (NO TORQUE)
The "SHIMPO" has a mechanical design speed control, which is top of the
line. Great idea. It's patented!
The Boston Wheel Model 75 is a fixed speed 75-RPM machine with a very
constant torque. The motor is not available off the shelf. It is a
proprietary design just for this application. Yes it is a gear motor. We
have added some changes to the design over the past 18 months to cool it
down a bit. The Motor continues to run excellent.

System. Each Boston Wheel has a removable wheel head allowing the operator
to remove the wheel and place it directly onto our banding wheel, manual

wheel, drop me an email at pmdd@msn.com.

Paul,
You better take him up on his generous offer. I could do it too but my
billing rate is $400 per hour.

OH!
Nice job of spamming the list, mr Paul Doherty...Great way to alienate
around 3000 potential customers! Really speaks volums about your business
sense!
About your Boston Wheel...As your fellow Bostonians Tom & Ray would
say...BOOOOOOGUS! The life expectancy of most wheels made today is longer
than the owners, and every wheel out there is height adjustable...with the
right bricks and concrete blocks.
Thanks for giving us the word on a wheel to avoid!

Tony Ferguson on thu 20 feb 03
Sure I would like to see the adjustable wheel and specs as earlier
requested.
What kind of studio application do you see applicable to your Boston wheel?
You mentioned as a banding wheel? Did I mistake your Boston wheel (banding
wheel) for a studio pottery wheel?
Thank you.

Paul, suggesting that your potential customers don't know what they are
talking about when they are attempting to compare your product to other
products on the market is not how you turn potential customers into
customers=2E
Rather, it might be more productive to try to get us to understand this
"new technology" and how it might be better than the existing products=2E=20=
It's your product, and the ball is in your court=2E YOU have the
responsibility to educate about your product=2E To suggest that we can't
have an opinion until we have bought is absurd=2E ALL markets are based o=
n
how the consumer relates to or identifies with the product=2E
With no "track record" within the industry, you should expect comsumers to=
be cautious=2E

Paul,
You say below that the wheel in question is set to run 75 rpm.
All the potters I know (including myself) use a variable speed wheel.
I'm wondering where you got the idea that a constant speed wheel was
appropriate for today's potters. You ever made a pot?
I suspect that a fixed speed wheel will be "hard to sell" in today's
market, and especially to the CLAYART group, who are a pretty well
informed bunch.
Sounds like you need a good competent potter consultant to fill you in
on current studio practices. Probably not me though, as my Potter's
Wheel Design Consulting Services start at $279.00 per hour, plus
shipping.
Lotsa luck,

As I remember in Motor Theory and actual practice, a series wound DC =
motor generates more torque as more load is applied and the rpm's start =
to drop off. Sure would be handy on centering when you really test the =
torque of the machine to have a nice series wound to add torque as you =
add load. Or, was the old prof wrong and the labs flawed..... hmmmm. =
Nope, actually saw it in 'real life' too.
