- 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)
Machine Shop 2 – Machining Skills for Prototype Development (57:33)
- 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
Machine Shop 3 – Machining Skills for Prototype Development (30:02)
- Good practice – clean up
- Small belt sander configurations
- Grinder operations and materials
- Deburring and buffing

Machine Shop 4 – Milling Machine 1 (50:33)
- Parts and controls of a Bridgeport Mill
- Quill feed
- Axis handfeeds & backlash explanation
- Gib locks
- Power feed
- Digital readouts
- Milling machine set-up – squaring/tramming the head square
- Squaring the vise – adjusting the vise so the stationary jaw is parallel to the bed
- Milling machine accessories and work-holding techniques
Machine Shop 5 – Milling Machine 2 (1:03:33)
- Square and hex collet blocks – used to hold/clamp parts to machine features on 4 and 6 sides of a part respectively
- V-blocks
- Hold-down clamps – used to hold large or irregularly shaped parts
- Using angle blocks – used to hold materials to machine features not perpendicular on a part
- Drill press vise – using a vise within a vise
- Lathe chuck with vise – can be used to hold parts in the milling machine
- Double sided tape – can be used to securely hold a part without distortion
- Squaring high aspect ratio parts
- Right angle attachment
- Slitting saws – used to cut slots/slits/features in a part
- Rotary table – used to machine circular parts, grooves, circles, and segments . A dial indicator or Coaxial indicator can be used to square/center the table to the X & Y axes
- 5C collet indexer – used to hold collets and to position parts in up to 24 positions
