Re: [Emc-developers] probably an un-answerable question

I'd consider using a used propane tank from a torch.
One of the throwaway steel tanks.
You want to make sure you purge it of propane, but after doing that you 
should be able to solder brass fittings onto it.

Those are good for a couple hundred PSI.

Many.

30 psi is less pressure than they hold when full of Coke (according to
the internet)

Like you, I have been googling. They'll goto 100 psi if you don't mind
the bottoms turning into hemispheres as they pop out, but apparently do
so with no ill effects on the bursting pressure.  Since I'll have sense
enough to stay below 50 psig, I think I'll be fine.  I just have to
cobble up a wire carrier (roll of chiken wire) to set it in, drill 1/8"
holes in the cap for a pair of brass tubes, and liberally GO-2 them into
the lid. Drill a 1/8" hole for another brass tube in the valve block to
pick up the air when its on, and see what if anything can be done to
make the fluid valve actually work. If I can stay below 5 to 10 psig,
little or no fog, and make an 8 oz coke bottle of fluid last a few hours
while little or no air blows out thru the swivel joints to overwork the
air compressor, I should be able to grin from time to time.

Thanks Andy.

I don't intend to abuse the coke bottle enough to need that, but thanks 
for the reminder that I might.

I'm thinking of poking 2 holes in the lid, one to let the pressure in
from the air valve, and one to get the coolant back out of the bottle.

The pressure could easily be 30+ psi in the coke bottle, am I designing a
hand grenade?


I think sodas are filled to about 60 PSI, but after poking 
holes in the lid, that may weaken it.
Pressure pots usually run below 5 PSI to deliver paint or 
whatever to a spray nozzle.

Be sure to watch the Oxtool (Tom Lipton) video. He has a rather cute seal
that puts an O-ring around a plug on the *inside* of the neck of the bottle.
Sorry but I don't have the URL for the video.

I'd have to say that 25 bar is way beyond my 2hp air compressor. ;-)

Thats a very impressive column of airborn water when it let go. I could 
see that translated to broken ear drums and maybe even a blown out 
window in my small garage too.  But the window is lexan, reported to be 
22 LR proof. Also tested by flying nut rock from my weed eater, and 
passed the test.

I think the coke bottle will work. :)

The little 8 oz plastic coke bottle can handle how many psi?

I'm thinking of poking 2 holes in the lid, one to let the pressure in
from the air valve, and one to get the coolant back out of the bottle.

The pressure could easily be 30+ psi in the coke bottle, am I designing a

You could always use a SodaStream bottle if you need more margin
(though they are larger)

Re: [Emc-developers] probably an un-answerable question

[linden]

aprox 100psi beleave it or not

have a look on youtube oxtools tom lipton made a coolant mister using a 
coke botle as pressure vessel like you have in mind may give you some ideas
