Greetings CNC enthusiasts!
What diameter or form-factor would you suggest is best for 2.5D routing/carving with a 12" maximum depth of cut? How wide or skinny should the spindle be? Do you have a favorite model or manufacturer of high speed spindle to suggest?

If I could have it all, I'd ask for 220v single phase with a very high speed spindle running at 28,000 rpm or faster.

My gratitude in advance for every response!
