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.
