[QUOTE="Nitroman, post: 1632505, member: 37986"] Thank you! I need to get back over there, but I end up spending too much money! I bought the 3-phase PM 1440 since I'll get a better surface finish over the single-phase. Added an American rotary 10hp that'll pull the 3hp lathe motor no problems. Quite a few installs on YT that show my exact convertor. These units run very quiet. I will make an enclose lined with acoustic foam to make it non-existent for noise. I asked over on Practical Machinist about VFD's; yes they are good, but the wiring is not for the noob or faint hearted. One fellow, who does machine-tool wiring told me he had done several of my model lathes. It will take him one full day to rewire the machine for a VFD since the controls all go through it. It all became a mess. I live where there are no machine tool experts, had even considered asking PM to have it rewired and I'd pay before they even crated it, but the complexity and departure from the original machine would void the warranty. I'll stick with the RPC. So I'm in for around $26k with shipping right now, and will have to add tooling, but am confident this will all come together. Like one poster said, cry now, cry once and done. [/QUOTE]
