Is there any downside to upsizing the motor HP on a machine like a 11" Logan? I was turning some 3" diameter aluminum and even with relatively thin DOC it was bogging. I know I could use the back gears but I'd rather just be able to power through instead. The lathe came with a .5 hp, I've since installed a 1hp inverter rated motor. Was thinking about upping it to 2 HP. The motor I installed will operate from 0 to 6000 RPM so, I can control the speed from the VFD easily enough.
I'd rather have a powerful motor rather than moving the belts around. My thought is that the only downside might be I exceed the power limits of the drivetrain. It's all cast iron though and seems pretty robust.
