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.


0. DO NOT operate the machinery while under the influence of alcohol or drugs. This applies to ALL machinery.
1. NEVER leave the key in the chuck. Never. Not even for one second. Never never never.
2. Do not pick up chips unless you are absolutely 100% certain they have cooled. Once they have cooled, let them cool some more. Even then, it is better to simply push them off with a brush or pick up the long stringy ones with a pair of pliers. Further, this should never be done with the machine running; long chips could snag on the part or chuck and start whipping around.
3. Parts should never protrude from the chuck jaws more than 3 times the diameter of the part without being supported by a dead or live center in the tailstock, or the steady rest. Parts shorter than their diameter should ideally be at least halfway in the chuck.
4. Disengage the feedscrew transmission when not using it, and of course the halfnut on the carriage.
5. Long, thin parts that extend out the back of the headstock should be sheathed inside a very loose-fitting fixed tube to prevent them from whipping around and bending over, essentially becoming a weedwhacker on steroids.
6. Regularly check that the chuck is firmly affixed to the spindle nose. There is a short allen key in the blue tool box that will fit between the spindle nose and gearbox.
7a. When polishing with abrasive paper/strips, never let it wrap more than halfway around the part. It can snag on itself and pull your fingers into the part.
7b. If polishing the inside diameter, never never never insert your finger in the hole. Wrap the abrasive around a small wood or plastic dowel that is significantly smaller than the ID of the hole.
8. Verify the spindle speed is appropriate for the diameter and material you are working on.
9. No long hair! NO LONG HAIR! Not even a ponytail is acceptable. If you have long hair, put it up under a hat or in a bun or something. Tying it back is NOT acceptable. We would rather see you looking silly than looking dead. If you don't believe me, do a google image search for "lathe accident" and you will see why. No loose long sleeve shirts, no dangling drawstrings on hooded sweaters, no loose jewelry/rings, no headphones, no neckties. If you are observed with any of these while operating this machinery, you will be asked to stop immediately.
10. Safety glasses are always a very good idea, however, if they fog up and obstruct your vision, stop what you are doing and get a different pair. It's still extremely dangerous not being able to see, even if your eyes are protected.
11. Do not wear gloves while working on the lathe. They can snag and pull you in.

Known Problems

Occasionally the lathe will have difficulty starting up the motor when the gearbox is set to 1620 RPM. If this occurs, stop the lathe, wait a few seconds, and try again. If still unsuccessful, select the next lower speed and work from there. It is unknown what the direct cause of this problem is.


The quill in the tailstock is now (finally) captive and should not disengage from the feedscrew with normal use. A slot has been machined on the underside of the quill and an 8-32 screw rides in the slot to capture the quill. If the quill needs to be removed, it is a simple matter of backing off the screw a few turns and then advancing the quill to its maximum feed to release it.

A DRO (digital readout) has been added to the carriage. This will greatly enhance the accuracy and usability of the lathe when doing precision work. These should be standard equipment on all lathes, IMHO. Make sure to turn the DRO off when not in use. It does not have an auto-off capability, and runs on a pair of CR2032 batteries. If the DRO acts funny (jumpy display, wildly inaccurate readings), this is likely caused by oil or other contamination on the capacitive scale, and must be thoroughly cleaned with 99% isopropyl alcohol.

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.
