It's a nice dream, but not backed up by reality. Several states have
introduced tort reform and capped damages. The result has been very
little reduction in cost, premiums, or improved care.

TOPIC: What grease for motor bearings
http://groups.google.com/group/rec.crafts.metalworking/t/586cd8f42e97c6d5?hl=en
==============================================================================

From: Ignoramus27020

Since I am going through the Clausing lathe anyway, I decided to give
some attention to the motor. The motor is a 40+ year old Reuland
motor. The only problem with it that I observed is that it
squeaks/squeals at 60 Hz. This is not the sound of the VFD frequency,
either. It is irregular squeak/squeal.

I suspected the bearings.

This motor has regular 6306 bearings inside and I will get the
replacements tomorrow. The ones in the motor were double shielded
bearings and that is also the replacement that I will be getting.

My first question is regarding the grease. The motor has no grease
fitting. The bearings were generously covered in grease. I would like
to know if I need to do the same with the new bearings, or it is
optional. Also, can I use white lithium grease.

My second question is about the dirt in the motor. The motor is quite
dirty inside, windings being covered with black dried
oil/grease/muck. I would like to remove that stuff, but safely, so I
am concerned that chemicals like oven cleaner or carb cleaner could
somehow deleteriously affect insulation. Has anyone successfully
cleaned old motors like that, thanks.

If they're double-shielded, they're greased from the factory, good for
life(of the bearing). Apparently the shielding worked if the innards
were that filthy. Usually, motors were dipped in varnish to
impregnate the windings and then baked. The stuff is fairly resistant
to solvents, I'd wipe, not dunk and check out a non-critical spot
first. Caustic will probably turn the varnish to soap, I wouldn't use
oven cleaner. VM&P naptha would be what I would try first, you might
want to check with a motor rewind shop to see what they'd use. The
naptha shouldn't dissolve the paint, either, it's supposed to be used
for paint prep to remove grease and not leave a deposit.

In that case, forget injection molding and think extrusion. You've got
something that's basically like a big T05 heatsink, so you should be
able to extrude as a complete part (no snap together) and then slice
into the appropriate lengths.

You could also just lathe and mill it with a 4th axis, taking a solid
plastic rod, bore the center hole on the lathe, then put in 4th axis on
the mill and mill the fins. A 24" rod should yield like 45 parts.

Wow, interesting. My wife's grandfather had a few still-life photos
hanging in his home years back. They were bowls of fruit or something
similar, nice, but not really remarkable. I remember asking him about
them one time, as I knew he had studied photography and film making in
Germany before he came to the US, just before WW2. He described a
process similar to this, taking 3 photos of the same thing through
filters, then combining them when you made a print. He said that when he
made them, it was a tricky process for a do-it-yourselfer with a pretty
low yield. It took a number of tries to get a good print. While they
looked unremarkable now, they never failed to get comments at the time
he made them, when he and had them hanging in his office.

Thanks for posting that.

There were lots of ways of getting a color photo back then, just that
most were inconvenient, or slow or both. Autochrome was one method,
involved colored grains of potato starch as a three-color mask layer
over a regular glass plate emulsion, was a lot slower than the slow
emulsions of the time due to the filtering, but could be developed
using regular photo chemicals of the period and when properly done,
left a color positive that could be projected in lantern slide
projectors. Another method was the tri-pack camera, used three
regular plates and three color filters, one lens with mirrors and/or
prisms inside to divide up the image. These could be printed using
carbro or other non-silver printing methods, the camera was bulky and
the printing was a long and messy affair,but could be done. I've got
WW1 color photos that were reproduced in a recent history. Not action
photos, stills and posed stuff, but still, period color photos. There
are several books that detail all the early history of color
photography, it DIDN'T start with Kodachrome! One thing about those
early tri-pack photos, they didn't depend on organic dyes that
eventually faded away. Technicolor was a similar silver-based color
method. If the emulsion and backing is still intact, the three silver
negative images can still be processed to give true color even today.
Amateurs without the money for a tri-pack could invest in a heavy
tripod and the three color filters and then take three shots in
succession using the filters. They'd have to make sure that the
camera didn't move and mark the negatives as to what filter was used
with each in order to get a decent print, it was done, but too much
fiddling around for only still-lifes for most.

Well ... I've not seen actually *wound* windings of anything but
copper (that I know of), but the fabricated windings used in the rotors
of induction motors are sometimes aluminum strips in the slots welded
to aluminum rings on the ends. My guess is that this is either for less
weight for faster acceleration, or to allow higher maximum speeds to
avoid the ripping apart from speed which I expect from the experiment in
question.

BTW I would feel that the motor would be more likely to
self-disassemble at 400 Hz if it were a 3600 RPM (actually a
little slower for slip) motor (2-pole) instead of an 1800 RPM
(4-pole) motor. I believe that most makers use the same rotor
assembly in multiple speeds of induction motors, so with the
3600 RPM frame, there would be more stress beyond the design
speed than in an 1800 RPM frame or slower.

Enjoy,
DoN.

When the current needs to be just so - Silver and zero-resistance wire
is used. :-)
Mostly in coils but some special purpose motors and steering devices.
When small size is needed but high power. Money is no object.

My ex-cow has a big wide tail, when she sits around the house, she sits
_around_ the house! Know what she put behind her ears to attract men? Her
ankles! Know the difference between my ex and a Cadillac? Not everyone has
been in a Cadillac!

Oops, sorry, just some ex jokes :-)

That maybe but her replacement was not a patch on her.

Are you serious?!? It's Cliffie, he doesn't have a substantial reference for
anything.

Any chance he could be out hitting the stump trail with a new song to

If McCain so badly screwed up his life, why can't he mention even one
example of how he did so?

No offset blanket, no offset roller. "Offset" printing involves printing
a negative image from a "plate" onto a "web" or "blanket" (often of
rubber), then impressing that rubber sheet against the paper to create
the positive copy. It also usually involves an ink-acceptor "plate"
photo-engraved with the print image - instead of type - that uses water
to repel ink from the areas that shouldn't accept ink.

This press just smunges ink around the spinning inking plate with a
brayer-like inking roller, then the roller transfers it to a frame of
movable type or an etched type plate (or counterfeit bill plate <G>),
which impresses the image directly onto the paper.
