i got this from my sister a while ago cause she was going to throw it away. I used it for a little while but the thermostat went bad so now i have a new pump. i was surpised at just how easy it was to do. i want to credit POLAND_SPUD for his how to. the only problem now is im gunna have to build a high pressure copper gun to prove it works well :D

all i used was a screwdriver, pipe cutter and socket wrench. i probably should have used a safety mask but i was outside and stood away from it. when you have all that you just cut the pipe in the two places and unscrew all the hardware and make sure not to mix up all the wires. then for an air filter i just used a pen tube with some cotton stuffed in it.

yeah these things are cool because you can build them so fast...

now you have to find a way join the compressor and several fitting toghether so that you could add a manometer, female quick connect fitting and ballvalve for venting... I used malleable iron fittings as they offer modularity so you can add more stuff later if you want to (for example an air tank or oil seperator)

firstr you need something that can join the tube with the rest of fittings..
for the first few months I had been using clamps for this but soon I learned that it wasn't the best idea... since then I've been using a home-made compression fitting built from two 1/2" male-female adapters with one or two steel and rubber washers sandwiched in between... it's really simple and it works pretty good

if you use both a compression fitting and threaded fittings your setup will be modular that is you can modify it and replace any part when needed... mind you that doing it this way isn't more difficult than soldering, in fact I think it's easier this way and yet it has advantages that I mentioned earlier

Question: Are they a standardized size? I have seen copper pipe roughly that size, and have compression fittings especially for them..

IIRC they are 5 - 6mm... I would have used used off-the-shelf compression fittings but It seems that they are almost impossible to get here...
