A citizen of the United States, who is not an "American Indian", as
they were known for a few hundred years, who is anti immigration, is a
sort of a contradiction, aren't they?

A public school teacher was arrested today at John F. Kennedy
International Airport as he attempted to board a flight while in
possession of a ruler, a protractor, a compass, a slide-rule and a
calculator. At a morning press conference, the Attorney General said
he believes the man is a member of the notorious Al-Gebra movement.

He did not identify the man, who has been charged by the FBI with
carrying weapons of math instruction. "Al-Gebra is a problem for us,"
the Attorney General said. "They derive solutions by means and
extremes, and sometimes go off on tangents in search of absolute
values. They use secret code names like 'X' and 'Y' and refer to
themselves as 'unknowns', but we have determined that they belong to a
common denominator of the axis of medieval with coordinates in every
country.

As the Greek philanderer Isosceles used to say, "There are 3 sides to
every triangle."

When asked to comment on the arrest, President Obama said, "If God had
wanted us to have better weapons of math instruction, he would have
given us more fingers and toes."

White House aides told reporters they could not recall a more
intelligent or profound statement by the President. It is believed
that the Nobel Prize for Physics will follow.

Looks like Grizzly already makes one, Although at 2 1/4 by 6 it's a bit big

From: "Wild_Bill"

Using a proper vise keeps many of the workholding forces within the vise.
When a table is used as a portion of the workholding apparatus, the table
needs to withstand much of the force used to hold the workpiece.

If the table bows or twists due to the workholding forces, other problems
will likely arise.

My light duty machines have cast iron tables, and in using proper vises for
workholding, I've been able to eliminate problems associated with bowing or
twisting.

I like to keep the work as close to the machine bed as possible, for the
most rigid seup, within reason.

I hope your project works for you as well as you anticipate it will.

As is often the case, this is as much a learning experience as anything.
The small vise will serve for most projects since I finally figured out how
to mount it. LOL. The larger bed vise one will most likely hand from a peg
behind the mill most of the time.

I'm pretty familiar with the area. It's not
immediately obvious at the opening zoom level,
but there are 8 markers in the "southern NH" zone,
even if a couple are over the border into ME:

Last winter we had I think one night that got to -30F.
Winter before, one night dropped to -34F.
This year we're renting it out, so I keep tabs on
the weather station down by the river as well as the
one on wunderground.

Between '66 and '70 I would have been walking to
school on Pease. I don't recall which year it was but
there was a big deal made about a few days of really
cold weather, at least one of which was a -60F chill
factor (daytime). I don't recall what the mercury
read (or whether we'd already replaced the Hg one with
an alcohol thermometer), but I sure remember wishing I
could have taken lunch instead of having to walk home
for lunch in that. (My mother was from MN, so my
complaints and then pleas to stay home for the
afternoon fell on unsympathetic ears.)

I used Walmart boat shoes and a safety rope. Then I found a roof hook
that you put on the end of a ladder. You hook it on the ridge and work
off the ladder. A little slower but way less scary. It's pretty easy
to move around.

The one time I used a water heater element in a 1" NPT fitting I
just used a bunch of Teflon tape on the threads and it sealed up okay.

I suppose if you are making adapter fittings in bulk you could chuck
the bushings up in a lathe and cut the square recess for the sealing
ring. The difference between the fat end of NPT and NPST threads
should be more than close enough to hold.

Oh, and Silver Braze the fittings around the heater element - if you
have a water circulation failure, the melting temperature difference
between ''Plumbers Lead Free Solder" (usually a 0.5% silver solder)
and silver braze could make all the difference.

Hey Karl - When you get *that* good at doing the repair, it's time
for you to stop tilting at windmills and make some wholesale changes.

That's the time I would get frustrated, call the local Case or John
Deere dealer and see if they did it any better. See about trading in
one of the old Ford tractors, where someone who only plans to pull a
gang-mower and not pound on the PTO can get a lot more use out of it.

Me, when they changed to the new emissions gas with the MTBE and
Acetone and other mystery chemistry added, and that blew through the
old diaphragm material in a few weeks... I got my Corvair Fuel Pump
swaps down to five minutes (and always on the way in to work, never on
the way home...)

Then I finally got smart and installed an electric fuel pump,
bypassed the factory mechanical pump... Problem solved.

(NOW they make the diaphragm sheeting for the fuel pump kits with
the proper modern rubber blends that will hold up to the fuel. Where
the heck were they in the 1980's?)
