Hey guys, I have a homier mini lathe and thinking about CNCing it.

After using the Bridgeport EasyPath CNC lathes at work and turning thousands of parts I have gotten an urge to convert mine, I woudl like it to be fully cnc and manual.

The main questions I have are what size steppers?

I had an idea for turning threads too, disingaging the spindle and driving the leadscrew and having the gear train to drive the spindle. Although it seems that would take tons of power.

Would a 300oz/in motor be enough for that? I would be hooking this up at the end of that screw and always have the halfnut engaged.

And for the X axis, I think i woudl only need about a 100oz/in motor right?

I was also thinking I might want to use a servo for the Z axis because if I miss steps, that would mean possibly throwing a rapid right into the chuck, that wouldnt be pretty for this I woudl definately use limit switches, kinda like how I should have on my mill


Let me know what you think.
