Class Notes
We have two classes on the Nardini lathe, a 101 that only covers collet work with manual feed, a 201 that covers the chuck, mechanical feed and threading. We also combine the 101 & 201 classes for experienced lathe operators. Check with @sebastian.wessels or @todd.franks on Slack if you qualify for the combo class. We drop the part where you do manual threading with a tap on the lathe when we combine the classes. The 101 class consists of the video below and then the in-person part where the instructor verifies that the student is capable after watching the video.
