Equipment Settings

Spindle speed: Be mindful of what spindle speed the gearbox is set to. Different diameters and materials require different spindle speeds. Consult your Machinist's Handbook, the internet, or the handy (but woefully incomplete) chart on the wall behind the lathe for appropriate spindle speeds. For example, brass and aluminum can be turned much faster than steel or cast iron.

Known Problems

The quill in the tailstock is not captive. If you crank the feed too much, it WILL disengage from the feedscrew, possibly screwing up your work. Be cautious of this. If you can see the keyway machined in the top of the quill, it's starting to extend too far. Stop your work, retract the quill, and reposition the tailstock closer to the work. This is a design flaw, not a failure of the equipment. We will (eventually) take steps to ensure the quill is captive, probably by machining a groove in the bottom of the quill and adding a set screw, as is standard on many lathes.

Future Ideas

Add a chip pan below the lathe to catch aluminum (and only aluminum, do not cross-contaminate!) for recovery and recycling in the foundry.
