Been there, done that.
I was building power test systems for HP TMO (now part of Agilent). The
units sent to Europe had some requirements that were universally
regarded with a shrug, but they weren't especially difficult to
The most obvious change was that they required a the neutral to be run
through a breaker, which in US practice would be thought dangerous.
Franklin's "experiment" showed that lightening and electricity were one in
the same. He did not "discover" electricity.
From http://www.codecheck.com/pp_elect.html :
"Around 600 BC Greeks found that by rubbing an 'electron' (a hard
fossilized resin that today is known as Amber) against a fur cloth, it
would attract particles of straw. This strange effect remained a mystery
for over 2000 years, until, around AD 1600, Dr William Gilbert investigated
the reactions of amber and magnets and first recorded the word 'Electric'
in a report on the theory of magnetism."
I believe Gilbert was a Brit.

I didn't say he did discover electricity, only that his experiment with
the kite and storing "lightening" in his bottle predated the work of the
fellows Andy mentioned.
In fact, Ben couldn't be officially considered a "US/Merican" citizen in
1752, but more properly a Brit.
I spoze also many neandertals (OBWW) discovered their hair standing on end
long before the Greeks got their zap off a doorknob or cat or whatever.

Well, if there was any sarcasm there I missed it...twice. I went back

Sorry, I thought you were saying the fence was no good and you had to clamp
a piece of wood to the table.
I have cut plywood like that many times with no problems at all; so I guess
you are just clumsy.
Go add a ground. Do any stupid thing you want.
It's always interesting to see all the aggressive opinions that come with many
electrical questions. Some have tried to explain the difference between a
ground and neutral, while others have ignored or misinterpreted it. But no
matter how you explain it, getting shocked is not a nice thing. With older
devices, those who survive are usually experiencing leakage current which may
be more startling than directly dangerous. Unfortunately, one can never tell
when this leakage may increase.
In a few very old items, reversing the plug may stop the problem, and you can
then put a polarizing plug on to keep it that way.
There is nothing illegal or dangerous about connecting an earth ground to the
frame, as he said below. However, a tool that discharges current through this
earth ground is dangerous and against any electrical code. Check with any book
or reputable site on this. Now, you could always put this into a ground-fault
outlet, but it would probably trip immediately.
In short, you have a potentially dangerous situation which shold be fixed.
Adding a ground will at least give you some protection if the leakage
increases, so the motor will begin to smoke before you do.
This is also the reason I run my shop with ground-fault detectors.
Both you and he are incorrect. Grounding an appliance (tablesaw) which has a
connection (advertent or inadvertent) will energize the ground throughout
the premises while the appliance (tablesaw) is on - a potentially fatal occurance
for someone else on the premises.

Really funny. In another post you say:
"In such a configuration, the frames of all other devices *which share
the same ground path* (emphasis added) will be energized. I don't
think you really want this.
Now it's "throughout the premises."
