About this Machine

The lathe is good for making round parts, composed of concentric cylinders and cones. When used with care, you can hold tolerances around 0.001 inches, but you should expect tolerances around 0.007”. It can be used to cut nearly any material that doesn’t create dust. (So, no wood!) The 3-jaw chuck can accommodate pieces up to ?? in diameter.

Machine Safety

Read the manual and this SOP completely before operating the lathe. Remember that you are responsible for your own safety and the safety of those near you when operating the lathe.

The cross slide feed handle(silver colored right above the carriage hand wheel) moves the cross slide in and out to make your cuts. It makes movements of 0.001 inches

Compound rest feed handle is used to move the tool toward or away from your workpiece in 0.001 inch increments on the markings
