Coaster

This was an enterprise project to raise funds for a project my students wanted to make.

Learning Objective
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.

• These can be bought but my students make their own
• Put the tool into drill chuck

• 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

• Align the aluminium so the turning tool is in the top left corner
• Move the aluminium as per the photos

• 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

• 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

• 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
