I use this Way Oil, bought 9 lifetimes supply for my Bridgeport mill and Logan lathe.
It is sticky and does not evaporate or smell.
I have seen a guy on e-pay selling it in small amounts. A few drops goes a long way.....
Or, meet me @ the next Orlando Hamfest for a free cup'o Vactra!!

Has anybody tried using chain saw bar and chain lubricant to lubricate the
gears?
There is an ingredient that causes the lube to become tacky and adhere to the
gears.
It seems like a good idea to me. I could not find the ingredients on Google but
did
find an article from bio-lube which is really neat as it is made from soy ,
vegetable
oil and that magical ingredient to keep it tacky.
Below is the link to Bio-Lube if anybody is interested. It is safe for the
environment.

I do know that sears sells a bar and chain lube that also has the " tacky "
additive "
but the trade ingredient is not given

Does anybody know if there is a JAN part number for the 12BA6 vacuum tube.
I could not find anything in Google.

R390 or R390A?
Lots of 6BA6's in the R390A. Look at my OLD discontinued page:

My tube list has the 12BA6 also as an 12BA6 / HF93 and an FSN of
5960-00-166-7665
searching on FSN brings up tooooo many sites.

I would be very wary about using any oil or grease inside the slug
tubes. Over time, they can be absorbed into the paper, which can
either make it swell (and therefore bind the core) or gum up and
stick the core to the tube. I've seen quite a few 390 transformers
ruined this way, though I rarely knew exactly what had been applied
to cause the damage.
I'd stick with very light applications of graphite or talc if you
insist on lubricating the slugs.
To clean lubricant out of the slug tubes, use cotton wads or swabs
barely moistened with a very fast-drying no-residue solvent like
acetone. Be careful not to do physical damage.
Best regards,
Don

Bicycle and motorcycle chain lubricants have this, as well. Whether
it is a good idea for 390 gear trains, I do not know. You're not
likely to be spinning the dial fast enough to fling the lubricant
off, so it doesn't seem as if it's really necessary. And one
shouldn't use so much lubricant that running or dripping is a
concern. I'd worry that the adhesive additive would turn out to make
the lubricant harden prematurely, but I have no data nor experience
to indicate this.
Best regards,
Don

While no expert here by any means, my gut reaction is NO! That "wax"
that is in the oil tends to dry out with time and leave a very nasty
residue. It i
s virtually identical to rock drill oil used in
construction and I can personally attest to the buildup and nasty gooey
nature. It would seem like a better choice would be a synthetic 90-140
wt gear oil. The trouble with that is that it stinks. So, this comment
probably doesn't really help answer the question.

I grew up in the midwest (Iowa) and when I moved to
California, I really really missed summertime thunderstorms.
In 8 years on the West Coast, I only once saw a storm that
had any appreciable lightning activity.
Temprement wise, I think that some people like me actually
find thunderstorms relaxing. The ozone in the air, the steady
roar of torrential rain, the bright flashes and booms I
actually find calming. Now I'm in the mid-atlantic and
although the thunderstorms aren't qualitatively as good
as the storms I grew up with, I am quite glad that
I'm back where we get thunderstorms.
Of course, being from Iowa I'm quite used to tornado watch and alerts too.
To somebody who didn't grow up in tornado alley, here is how they work:
A tornado watch means that you should put a new tape in your camcorder,
and be sure it's readily accessible.
A tornado warning means that you should go up on your roof and try
to get some footage of the tornado so that you can be on the TV news. It's
very handy that most town in the Midwest have tornado sirens, just in
case you aren't watching TV or listening to a radio when one comes.

What He Said Above. We get some pretty intense weather here, and the
National Severe Storm Center and National Weather Center were located here
for good reasons. The other thing we do -- here, at least -- is switch to
the indoors 2m and 70cm antennas and battery power on the V/U rigs and
start listening on the local repeaters. Eventually, if the wx is nasty
enough, someone will start a SkyWarn net on one or more of the repeaters,
and we start calling in big hail, high winds, and funnels.
It's a lot of fun, and frequently we hear one or more of the weather
guessers say exactly what we said, only they say it 10 to 15 minutes later.

Cecil,
I do NOT ground all as well as I can - THEN - isolate the whole thing
!
My initial comments on the *VARYING* codes refers to localized
ordinances that SUPPLEMENT the NEC. I definitely DO tie ALL grounds
together.
As you pointed out in YOUR post regarding the magnetic effects,
disconnected PCs can be destroyed.
The codes here have been in a state of flux since late 2004. The county
has adopted, AND made mandatory, the Internal codes for residences and
commercial structures.
There has been a LOT of pain and financial cost to this. Some of us
that had new siding put on after a heavy hail storm, have had to have it
ALL removed. This is because the underlying "wrap" didn't meet the
*NEW* code. Fortunately I went with 1/4" insulation made with Tyvek
wrap. Precisely the wrap specified by the new code.
While I've done nothing electrical - antenna, ground, and the like since
the new code came in, I'm having a professional come out that KNOW the
new code, and carries it with him.
Then I'll have the groundwork laid to go forward. [NO Pun Intended!]
I am NOT in the county per se, BUT in a city *IN* the county. It simply
adds to the confusion and frustration.
I'm STILL looking for the BEST overall solution. If it means do MORE,
then I will!
