Johnstone had or has a crank up lift that attaches to an extension
ladder for getting compressors on a roof. I don't know if they were
renting it or loaning it out with the sale of a compressor. I'll have
to ask the next time I'm in there.
There is a nice professional winch for that. Larger requires a crane
or depending on expanse of roof and size, a Helocopter. Fast smaller
jobs, just call a sign company crane truck. They are happy to do quick
fast jobs and be on their way. $75 for a fast half hour job is the going
rate here. They can handle 5K to 10K BTUH roof units.
Dammit Paul, You enlighten him and how in Hell are we gonna get him to
continue carrying 20 ton compressors up that ladder/ :-p
In all seriousness.. Get a hoist for that job. Ladders are not a place
to be fooling around with heavy loads.
Johnstone marks the retail prices on their invoices for your use.
They have a sliding scale wholesale just like the 14 other vendors I
after a lot of years in the business, I am gratified that you are
here to drop these pearls of financial wisdom on me. Much of what we buy
from the 14 different vendors is not catalog listed. Computer downloads
of inventory are updated on a regular basis. Also having a nice little
proggie to compare pricing is a real treat also. I merely mention
Johnstones prices is because most of the folks here use that vendor and
can verify my statements. Now if you wish to sell products to your
customers at wholesale..Thats fine with me. Do you also do service and
installs at cost too?
Is this your game of my dick is bigger then your dick and my daddy can
beat up your Daddy?;-p
there are more places than Johnstone, as wonderful
You should be able to do something as simple as replacing an air handler
motor. My father taught me how to wire a house when I was kid. I used to
build Frankenstein machines and being no fool, would get one of my
little brothers to plug it in. Little bros never got hurt,....much. :-)
Speaking of wiring, when I had my first ouse built in '71. I did the
wiring. When inspector came out, he asked me if I was an electrician,
LOL! As a teenager, I used to build/asemble x-sistor radios to make some
spare money. I was active HAM then.
I remember my parents getting my older sister a transistor radio and
it had a 9 volt battery about the size of a C cell with snap connectors
on either end. I haven't seen a battery like that in many years. It had
to be the late 50's or early 60's and of course I had to take it apart
to see how it worked. 8-)
Gemini, Apollo and some other assorted unmanned vehicles. The
Electronics is sometimes more valuable then lifeforms. Duck hunting was
good in Huntsville. Hated the damned humidity. Space employed millions
in the 1960's. If you want to see the wonders of real environmental
systems.. Just look at the modern 767 or the new Airbus aircraft.
The Concorde system was also developed by a Rockwell team. Another is
the Huge Passenger Ocean liners... I think most of those systems were
based on designs by Garret Industries Air Research.
Electronics packages were a little bigger for the same job back then.
I know that watt density is much greater now than in the past but the
use of switching regulators rather than shunt regulators may let the
electronics run at lower temperatures and the newer CPU's are a lot
less heat sensitive. I wonder what range did you have to keep the
temperature for the older electronics? I was able to get my hands on
some Apollo Saturn command receivers through the school surplus program
back around 1970 and the stuff was incredible, all discrete components
making up the tone decoders and the UHF receivers were all gold plated.
Man do I ever wish I still had that stuff. Oh yea, do the newer
passenger plane use more fresh air? I remember a lot of controversy
about the amount of air that was recirculated in passenger cabins some
There were no CPU's Per se.. It was mass integration called Micra's.
They were actually in a metal sealed flat very small(for that time) can
The tiny gold wiring was installed by machinery invented under
Government contract by North American Aviation(Rockwell). They were
taken by the Johnson administration and given to Texas Instrument, thus
bringing that company out as a major supplier.
As for cooling and heating... Much of those equipment needs were served
by immersion in FC77 or FC75..Which was then heated or cooled by other
methods as needed.
I wonder what range did you have to keep the
Close tolerance.. Wide ranges in environmental chambers were designed
for the unlikely possibility of environmental failures in space.
Too bad you didn't get your hands on some of the S band radar Moon
mapping radar. They were solid silver.
I was able to get my hands on
Scrubbers etc.. Check out Air research. Ain't much air at the altitudes
some modern transoceanic passenger planes fly. They need the altitude to
cut heavy air drag thus giving the most bang for the fuel dollar.
I remember a lot of controversy
I don't think you want any circuitry etc from some of our early
satellites and much of that was nuke reactor powered. Two fellows were
killed when loading a dispersing satellite, with Barium..Which by itself
is inert. They made a mistake and radiated it with Ku band to see if it
would reflect. In Air it becomes active when radiated and exploded
killing both and totally demolishing a laboratory and scattering nuke
material all over the place. It was scheduled to lift off from Pt Mugu.
Hughes Corporation made some really nice satellites with a lot of our
equipment on board. They still do and so does or did Raytheon. I am
amazed that you got any equipment from the Apollo program. All we had,
was destroyed rather then send it to salvage. As was the Mercury and
Gemini equipment. The Space suites were saved to be utilized for further
research and as museum displays. I understand there is a display in
Paris of some of our space hardware antiques.
The command receivers were made for the booster itself and on the
outside was stamped "NOT FLIGHT QUALIFIED" which led me to believe
they had been test and development units. They were completely sealed
and had the Bendix twist lock connectors with the gold pins, etc.
A lot of that material made it to the surplus depots where schools
and and other government agencies could root through piles of stuff
that originally cost untold thousands of dollars to obtain. It was
amazing, one transistor would be packaged in a box the size of your
forearm and it was all super quality mil spec and aerospace spec parts.
It was a regular candy store for anyone interested in electronics.
