Michael,
Cheap 12 Volt air compressor, $7.99

Cut the hose, insert tank made of PVC tubing, with an out going valve.
Charge the tank.
Put blow nozzle in end of hose (mine came with two), open valve.

Cheap, yes.
Effective maybe, depends on your needs.

I find the need for a small jet of compressed air to blow out chips etc from
time to time. I am thus looking for a source of compressed air to which some
sort of air gun can be attached. It has to satisfy three requirements:
1) It has to be cheap,
2) It has to take up little or no space,
3) It has to be cheap,

I heard some people simply use a spare car tire. I asked at Summit tools
(who carry all kinds of air stuff) if it is feasible to attach a hose and an
air gun to a tire, they did not think so. I really do not want/need a
full-sized compressor. A compresed air bottle seems a bit of an overkill.

Any suggestions?
