Usage & Safety

The metal lathe is both a precision machine and also powerful enough to seriously hurt you. It needs to be treated with the same respect you would give any precision tool. All members are welcome to use the machine after being shown how to use it properly.

  1. Only trained members may use this machine.
  2. Tie back long hair, remove long sleeved shirts and jewelry.
  3. Eye protection must be worn when machine is running.
  4. Check all tooling and machine for damage before using.
  5. Sweep / vacuum up chips and leave the machine clean.
  6. No unconventional / unsafe use.
  7. You break it, you buy it!

You MUST be trained before using this machine. Please consult a member who knows what they are doing. You can help a guest with a job but guests are not permitted to use the machine themselves.

Note that knowing how to use a lathe machine is not sufficient - You must be shown by a trained member the intricacies of our machine.

Feeds and Speeds / Feed Direction

  • Learn about feeds and speeds for the cutter diameter and material you are using. Too fast or slow RPM can damage cutters and make it harder to work.
  • FS Wizard web and Android apps can calculate facing and turning speeds
