Re: Pressure regulators for airbrushing.2

ROGER HINMAN
 

I've been using CO2 tanks for at least 10 years now; the initial cost was around $200 for the regulator and valves, but the recurring cost is around $20-30 a tank. My local dealer takes in the empty one and gives me a full tank. I'm not a full time painter and I get a couple of years or more out of a tank.

Lester,
since we know each other personally, and are local to one another, may I start an offshoot of this thread with you. And I seem to recall you had a background of dealing with numbers so....
    Could you state in general terms, the cost (minus the airbrush since those are personal choices) of the set up for a compressed air arrangement. Others can chime in also, please.

Set the cost long term say over five years so the tank pressure test costs can be rolled in.

Bill,

Is Monon 1 the car in which you are interested? I have a copy of the ad from the NMRA, but it is too faint and small to copy. The original ran in the September 1948 TRAINS. I'm sure Kalmbach could help.

Yours Aye,

It was quite distinctive and useful (I remember it listing cigarettes from virginia or north carolina).


Can anyone help me locate this as I can't remember where I've seen it.

OK - before this gets too out of control, I would like to point out that if you get a CO2 system, you can also use if to dispense beer from kegs, as I do, which is a serious plus!   ;)

I would like to add to this conversation about the use of CO2, a recognized greenhouse gas which is increasing in concentration in the Earth's atmosphere.

The use of CO2 would seem reflexively to be bad, as global efforts are needed to decrease CO2. However, most industrial bottled CO2 is captured from natural gas extraction as a waste product. This CO2 would end up in the atmosphere with industrial use or simply left ignored.

As long as we produce and use natural gas, we will have CO2. Avoiding using CO2 for painting freight cars won't make a difference in the climate.

Re: Pressure regulators for airbrushing

Dennis Storzek
 

I'm also wondering where the 3000 PSI came from. Doing a little research on what threads are used for CO2, I find that carbon dioxide goes liquid in the tank, and that limits the pressure to around 850 PSI at room temperature. If the gauge on the regulator really goes to 3000, it may be a nitrogen regulator. If the GAUGE READS 3000 PSI, it's either screwed up, or you have a bottle of some other gas... I hope not oxygen.

Best to take the tank into a gas distributor, and let them determine what it is, and fit it with a suitable regulator and gauge.

If my original post had been read fully, including the post I quoted, one might have noticed
that I was referring to the use of a Harbor Freight regulator on the full tank pressure.
No where did I suggest that 3000 PSI should be used in an air brush. 
When I am risking my personal safety around highly compressed gasses, I want equipment
that is worthy of trust, not the "El Cheapo" brand.  But I suppose some folks do not see
a risk factor in high pressures.

You must have some serious premature drying issues if you're using 3000 psi HP air.  Plus it must beat up the models pretty bad.  [/sarcasm]

Re: Mystery car

I suspect that the trucks on that car are replacements for the originals.
The NYC cars had trucks with integral plain bearing journal boxes when they
were built and were later converted to roller bearings which could be seen
when the journal box lids were removed.

Tim O'

Thanks, thats a very interesting shot........

While your find has Andrews RB trucks, the HCMX still had friction bearing Barbers S2 ..... If I remember correctly the shots I was reviewing several hours ago on the other computer.

I use diving air. It's dry and filtered.  In addition, the air is contained in diving tanks that are no longer in use by divers but they have to be hydro tested every five years.  The tank has two gauges, one that shows the amount of air remaining and the psi gauge.

Re: Pressure regulators for airbrushing

Bruce Smith
 

Ben,

While Chuck may have overstated the pressure by about 3 fold, the internal pressure of the tank and therefore the pressure seen on the high pressure side of the regulator is about 800-1100 psi… So his point about buying cheap equipment is well made.  In addition, those cheaper regulators are more likely to blow out their diaphragms, which, if it happens while connected to an airbrush could indeed make a serious mess out of a steam era freight car!

Bruce

Andy I use a CO2 bottle with regulator. My bottle is only five pound so I have to exchange it or have it filled more often than your twenty pound.  The places I have it filled ( in MN Toll or Minneapolis Oxygen ) both sell various regulators ( I have  0 to 60 ) and can replace the one you have with another.  I am sure your CO2  suppliers can do the same.
