starter motor to drive air compressor-not

[cookie monster]

bought an air cond compressor to rig up as an air compressor. unfortunatly the space i had in mind wasnt big enough-bummer.
got me thinking though-why not use a 12v motor to turn the compressor? a friend had an old starter motor lying around, so i grabbed it, bored the front out to take a bearing to support the main shaft. then turned up a pulley for the shaft and got a belt to fit and mounted the starter motor piggy back fashion.
gave it a thourough test tonight pumping into my air receiver. well it works ! but the starter gets mighty hot and starts smoking abit when the pressure gets to about 80psi. had it up to 110psi but very hot ! so unfortunatly will have to put it on the
'well thats a good idea' pile.
any body got any other ideas how to drive the compressor????

A friend of mine made one with an old lawn mower motor connected to it.

not exactly small or light, but still transportable. (he has a ute so no biggie there)
Works a treat tho, good enough to run air tools, even a rattle gun with a small tank from a truck. Very cool, but probably not small enough to transport around in a wagon.

Unfortunatly starter motors are designed for high power output for short durations, you need an air cooled motor or perhaps try running the compressor inlet to suck air through the motor, small chance, probably not enough air flow still.
