Always the cheapskate DIY mad scientist, I started to ask myself why air compressors are so expensive. And the answers seeemed to be that a good air compressor needs to have a high psi rating and lots of air flow capacity. If I understand correctly, this means I should be able to run big power tools straight off the compressor even when the tank runs out of air. And it means the tank will, theoretically, fill quickly when emptied.

But I'm a pretty patient guy. And nobody is holding a clock over my head when I tinker with my car. So if the tank runts empty, then I really don't mind taking a break until it refills. So if I were to buy a cheap 1hp or 2hp compressor that were rated at, say, 125psi and then used it to fill a HUGE freaking air tank (maybe 15 to 20 gallons), then why should this not meet nearly all of my amateur wrenching needs?

Am I thinking too much here? Or is this a sensible idea?
