Did think about a vfd same as the spindle on the router but are you not limited to 3 or 4KW doing it that way? Most of the industrial screw compressors I've seen that sell reasonably cheaply are bigger than that, the smaller ones & single phase compressors seem to sell for a lot more money, I'm guessing because there is far more demand for them from people like ourselves lol.
