I have one of the early machines, 2007 i think, updated spindle drive years ago, I have worked it hard over the years but it has always lacked in the metal removal rate. The machine frame itself seems capable of taking out more meat from a block of aluminum.
So, I need a hotrod project and switching out the 1.5 - 2 hp motor for 5hp pullys/belt etc. and the corresponding VFD seems a fairly doable venture.
I was wondering if anyone has already done something like this and what was the experience like?
