Tim,
One of the many things I should have explained
Feed, moving the tool from right to left, toward the chuck,
(there are two dials on the left of the machine, down below some of the stuff)
The dial on the right changes the amount of cutting feed when the spindle is turning. (I think the other one changes direction of feed.)
With the knob turned counter clockwise, the tool advances .0025 per revolution of the chuck.
With the knob turned clockwise, the tool advances .005 per revolution of the chuck.
With the knob turned in the center, the tool advances .010 per revolution of the chuck.
The paper manual gives different feeds for different gears. This setup above is probably the most used.
The option for changing gears allows you to make different threads than the ones that accompany the feed rates that the lathe is set up for, .0025, .005 and .010. My memory doesn't cover what threads accompany that gear set up.
