I'm thinking about buying the G0519 Grizzly mill/drill/tapping machine. The machine is a gear head design. I only have three phase power thru a phase converter. The machine lists a top speed of 1970rpm. I really would like to have a higher top speed for woodworking tasks. Can a VFD accomplish this? If so, will the VFD impact the automatic tapping feature of this machine(when in tapping mode the machine will automatically reverse the tap back out when the preset depth is reached)?
Enco sells the very similar 325-5184 machine. The major difference being it is single phase and doesn't have the auto tapping feature. Would this single phase machine present better options to increase the highest speed.
One other option is the G9977 Woodworkers/Metalworkers mill. This machine is alot more money, and has the opposite speed range issue. 420RPM as the lowest speed. This machine is single phase and I'm not sure how to slow it down when needed.
Nothing really hits the sweet spot for me. Advice please.....

Trevor
