Just a dumb question, I work at a place that sell air compressors, why do modellers spend $200 or more on a compressor that will only do air brusing, when for the same price you can get one that does everything?![Confused [%-)]](/emoticons/icon_smile_perplexed.gif) For example, impact use, sanding, painting, and nailing? There is most likly some obvious answer for it too? |

I've got my compressor from an old refrigerator, I've added a receiver made from old big metal can. It works perfectly, no more noice than from a refrigerator (it IS a compressor from refrigerator), gives 30+ psi if necessary, turns itself off when not needed, and so on. I've added a bit of additional regulators (for pressure, for example), but it worked just fine without them. It costs me nothing, it took 2 days to build it (but I've already had both can and old refrigerator), it's pretty much silent, it will work nearly forever, I think it's superior to specialised airbrush air compressors. On the other hand, I never used a specialised air compressor. :) I've made this one couple of years ago for completely different task, I'm pretty new in airbrushing.
Cons: you have to have a moisture filter. Can't go without it. It's pretty easily done in home also, though. Same with oil filter - some compressors from refrigerators can spit plenty of oil occasionally - again, pretty easy to made at home.
I've seen others using same design... Here it goes... http://www.briansmodelcars.com/tutorials/tutorial.asp?TutorialID=28&CurPage=1
The only reason to use specialised compressor, I think, is because most people don't want to spend time looking for something else and re-building/modifying it. I may be wrong, but I doubt it. :)
