It shouldn't ... unless you're running a small lathe and there's inordinate friction in the gear setup or if the cut is too deep. The G4003 is strong enough that neither of these would apply.
No. I just am new and this is my first lathe. I haven't had much time to experiment much. Yesterday i was trying different feed speeds and it seemed to affect spindle speed. I will check today with a ram meter. High rpms seem excessive, but being new Im not sure.
Hi Tod
No, the G4003 is a Geer head lathe. The spindle speed is only changed when the head gearing is changed or motor RPM pulleys are changed. The feed is set by quick change threading/feed gear box witch is driven by the spindle RPMs.
Head Stock gears set the spindle speed. {A, B, C}×{1, 2, 3}
An output from the spindle drives the back gears which in turn drive the Norton Gear Box which sets traverse speeds (or thread pitch)
