If you are going to remove the motor, etc, this would be an ideal time to replace the motor to run on a more easily available power supply.You're absolutely right! After thoroughly cleaning and lubricating the bed, the saddle now moves smoothly without any issues, making it unnecessary and risky to scrape the ways. However, I have decided to proceed with the removal of the motor, belt, pump, carriage, and other components. This will allow me to fine-tune the adjustable parts and replace any simple components as a proactive maintenance measure. While everything is disassembled, I plan to take advantage of the opportunity to apply body filler to areas that require it. My ultimate objective is to restore the machine to its original color through repainting. I should note that I will not be removing the headstock, as I understand it is considered almost a crime against humanity due to its importance and significance in the functioning of the machine.
I don't know the details of the Montreal power supply, but in the States, 220 volt single phase is the norm for domestic supply.
Maybe your best option, if I'm correct on the 220 volts, would be to get a 3-phase 220 volt motor (easily available) and a quality VFD, such as a Fuji, to power your lathe.
