air compressor conversion

Northern tool and others sell replacement motors and pumps, but for the price you might as well buy another compressor whole, even used off CL, and strip down what you have to use as an auxiliary air storage tank to extend your capacity. We do it at work all the time. Cuts down on run frequency under load, but also has to run longer to fill up. Still worth it if you're using tools that take a lot of cfm.
