I do not doubt that the ad is true, but I have to wonder why any lathe
would need a 20 HP motor. I have hard times imagining how even a
fraction of that could be expended cutting metal with a single point
lathe bit.


Any idea of how much pure force it takes to simply spin up a 2' in
diameter chuck, let alone a 10' long work piece of that diameter, in
any reasonable amount of time?
