Induction

This machine requires induction to use.

To get an induction you must first review these videos. You must do this BEFORE attending the in-person induction (booked via event bright).

Changing the Chuck: https://www.youtube.com/watch?v=K0pwJzHfJ50
Notes:

  • We have only 3 cam locks on out lathes.
  • Stoning the chuck is not necessary. Keeping the precisions surfaces free of chis is essential.
  • We use plywood instead of a block to protect the ways.
  • Waxing of the chuck is not necessary.

Skills - Blondihacks: https://www.youtube.com/watch?v=H6Dnmd3lDzA&list=PLY67-4BrEae9Ad91LPRIhcLJM9fO-HJyN
Only the following videos are mandatory:

  • 1: Theory
  • 2: Tool Bits
  • 3: Facing
  • 4: Tail Support
  • 5: Turning

It is recommended to watch the entire series.

Once you have reviewed the videos, book an induction on Eventbrite for the lathe induction.

At this in-person induction we will review how our machines work and have you perform a few simple operations on the lathe.

This induction covers both lathes.
