Making a tube so I can splice two refrigeration hoses (manifold gauge hoses)
together since nobody is willing to sell me the needed fitting to my 30 lb.
bottle of R-134.

Start with 1/4" diameter by 2" long piece of air hardened steel. Put it in
3 jaw chuck. Drill full length with an 1/8" drill bit. Try to cram it into
the hoses, too big. Back into the 3 jaw, live center in tail stock, reduce
the diameter, flip it end for end and reduce the rest to match. Clean up
with a little piece of emery cloth. Project complete, except my hands are
filthy black.

Tools are relatively clean. Chuck key is pretty clean. 1/4" rod is brand
new. Why is machining so filthy? Does this happened to you guys also?
Seriously, I could do a brake job on my truck and only get half as dirty!!
What gives?

The approved way is to buy or make brass barbed connectors to make
Frankenhoses. Hidden at your all-night WalMart with the air tool supplies.
Likewise braze adapters out of brass pieces cut from off-the-shelf
fittings.

Of course it is an EPA felony to mix up your refrigerant kit, or retrofit
R12 gages to R134a fittings, etc. So this is, um, a purely hypothetical
suggestion, for educational purposes only. I am required to disclose that
you should discard all your R12 gear and replace it with Chinese versions
with original government-approved fittings.

Betcha didn't know metalworking could be criminal.

Betcha never thought criminal law would incorporate metalworking
specifications. Thou shalt not mix left hand threads with right, it is an
abomination. Cf 40 CFR (http://www.epa.gov/air/caa/).

Perhaps you are a dirt magnet. I have the
affliction, and it may be hereditary. I
could walk through a level 7 clean room and come
out with dirt on me. Forget
about wearing white, it's just an invitation to
disaster. My wife thinks it's some kind
of negative charge thing---she is sure that dirt
will jump up to 20 ft just to cling
to me.

Richard,
You are so right about the above. I guess I need to go from a 1/4" flare to
an acme thread. The web site indicated about 3 messages down show the right
fitting. I simply don't understand why the 30 lb. bottle of 134 did not
come with a male 'acme' thread instead of the old 1/4" stuff. I did go to
my local ACE hardware to pick up two fittings that I could silver solder
into one. As soon as I saw that they had 3/16" and 1/4" barbed hose
splices, I purchase those. One of those should be a good fit for my two
cobbled together hoses. BTW, my local ACE has lots of brass fittings,
however, they tend to be about $ 5-6 each.

Thanks for you ideas.

Yep. Illegal adapters.

You have iron oxide (black) on your hands. Micro ships
or scraping tiny bits or from grinding / sanding.

I turned some custom made Iron. That was full of carbon!
It smelled of oily carbon.

It may depend on whether it was sold for auto use or fixed refrigeration.

It's the exact same R-134a inside the bottle, only the fittings are
changed to increase the prices...

Adapters between SAE Flare and ACME Flare are readily available
premade at any refrigeration supply house, for a lot less than it
costs to make them. I have them.

You're likely describing the entire group here, guys. We DO things and
we MAKE stuff and we FIX stuff. That gets us dirty. End of story.

I wear white only in my nightmares.

Yep! cast iron is dirty stuff! If you have a shop vacum, its a good trick
to get the nozzle near the gutting tip and collect it as fast as it comes
off the work. Its abrasive and sticky when it gets rusty so wire it off the
ways of the lathe as soom as you finish the job .
