This was an enterprise project to raise funds for a project my students wanted to make.
By making an engine turned coaster KS4 GCSE students will learn and apply knowledge in a practical situation. This knowledge covers use of an engine turning tool and CAD / CAM. This project was used as part of a enterprise activity where students made various products. By using this project in their enterprise activity students gain entrepreneurial skills and begin to see the link between time to make / materials cost Vs sale price.

Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Engine Turning Tool
- These can be bought but my students make their own
- Put the tool into drill chuck
Step 2: Prepare the Guide
- Create a guide that has lines spaced at 20mm apart, arranged in the pattern shown
- Draw the lines of a flat piece of wood
- Clamp to drill plate
Step 3: Engine Turning
- Align the aluminium so the turning tool is in the top left corner
- Move the aluminium as per the photos
Step 4: Vinyl
- You have a few options here......depending on what equipment you have access to.
- I cover the whole surface with the vinyl.......laser cut it.......peel off unwanted sections (best bit :)
- Or use a plotter, then stick on your design
- Or cut out with scissors or knife then stick on
- Or buy some adhesive shapes, letters, or whatever and stick em on
Step 5: Varnish
- Use Polyurethane varnish......it must be a water based varnish or the vinyl will peel
- Put an even and very thin layer of varnish on...it only takes 10-20 mins to dry
- Repeat until you have four coats
- The varnish protects the aluminium from scratches and stops the vinyl from peeling off
Step 6: Enjoy :)
- You can get vinyl in a massive range of colours including carbon fibre! Ebay is a good place to get supplies from
- Now go and make awesome coaster / name plates
