There are some great videos on MIT's website that discusses shop safety and techniques. I have listed the links below along with their contents. You will be most interested in the lathe videos for our current use, but the other videos are very informative.

Machine Shop 1 – Machining Skills for Prototype Development (Length: 40:32)
- Basic tour of the machine shop
- Layout techniques (including transferring hole locations)
- Basic tools: drill press, band saw, belt sander and grinder
- Locating and drilling holes (includes using a center finder and deburring)
- Tapping holes (including using a tap guide)
- Drilling holes
- Special drills for plastics and hard or abrasive materials
- Drill press limitations
- Bandsaw
- Suitable speeds, feeds and materials
- Bandsaw setup
- Using the drill press vise
- Good practice – clean up
- Small belt sander configurations
- Grinder operations and materials
- Deburring and buffing
- Finishing techniques
- Parts and controls of a Bridgeport Mill
- Quill feed
- Axis handfeeds (11:20) backlash explanation (12:15)
- Gib locks (14:40)
- Power feed (18:33)
- Digital readouts (21:07)
- Milling machine set-up – squaring/tramming the head square (22:37)
- Squaring the vise – adjusting the vise so the stationary jaw is parallel to the bed (32:33)
- Milling machine accessories and workholding techniques (41:15)
- Square and hex collet blocks – used to hold/clamp parts to machine features on 4 and 6 sides of a part respectively (1:02)
- V-blocks (2:10)
- Hold-down clamps – used to hold large or irregularly shaped parts (3:40)
- Using angle blocks – used to hold materials to machine features not perpendicular on a part (6:15)
- Drill press vise – using a vise within a vise (8:29)
- Lathe chuck with vise – can be used to hold parts in the milling machine (11:11)
- Double sided tape – can be used to securely hold a part without distortion (12:00)
- Squaring high aspect ratio parts (16:02)

- Turning between centers (15:40)
- Face plate irregular shapes (19:00)
- Face plate thin materials (21:13)
