Currently restoring a 618 I found a few months back. I got it mostly complete aside from a motor and related counter shafts. My question is what direction should I go with powering this lathe. I have a new 1/2 hp motor laying around but I do not have the counter shaft. Should I get a counter shaft on ebay or possibly go with an entirely different motor powered with a VFD and is it feasible to not use the counter shaft with a VFD setup? I could even do a 90 VDC though the motors are more expensive. The reason I ask is the counter shafts are pricey and I could go with the other options for nearly the same price, but keep in mind I do have the 1/2hp motor and a nice drum switch to go with it. Just looking for some ideas as I really cant decide. Thanks.
