FragTek's first home made single stage...

Considering he'll be using propane for his first unit,

Here's the zippo testing way from my parts you'll need.

A zippo is like a butane lighter if you didn't know.

You fill your unit static charge to 50 psi, then take the butane lighter and light it and move it around by the joints. This will tell if theres a leak by a small flame coming from the pipe. :)

It works really well, dont trust your pressure gauges as oil will absorb some of the propane. To positive pressure test, braze an access valve to both discharge and suction of your vacuum pump (rotary compressor in his case). Remove the valve peice from the suction one and hook your charging hose (yellow) to the discharge. Open all the valves and turn on the rotary, fill your single stage to around 250 psi and then do the soapy water test.
 
rofl I dont know if I like the idea of playing with fire around a propane charge system that might have a leak :p lol
 
You won't. Propane needs oxygen to burn. It cant burn into the tubes and positive pressure makes sure it will only burn outwards.
 
Scary kempez?

Its a little scary the first time but it quickly loses its thrill if you know how to work and are careful.
 
Just found out I bought the wrong kind of copper tubing, bleh.

Just now ordered the right stuff from Under The Ice. I'll return the other stuff to Lowes tomorrow as I'm pretty sure they don't carry the right stuff as I would have seen it.
 
K Frago! :) Hopefully your filter, capillary, and manifold will arrive soon so I can get it packed up with a few goodies for you.

Yup, just lemme know the total for it all when its ready to go and I'll ship it off with the starter.
 
Sounds good mate.

Stuff should be here pretty soon. I've begun work on the canister.

EDIT: Damnit I just realized I used mate, the british are rubbing off on me!
 
Yeah I picked up the habbit a long time ago and haven't tried to quit :p

Just getting my practice in for when I visit England :) Maybe by then I'll blend right in, hehe.
 
Hahaha I'd bludgen his cascade if he left the USA. :)

But his rotarys just arrived I expect an update in a few minutes.
