This is a project I run in my after school engineering club, normally air/steam engines are difficult to make and even harder to get running, I studied various plans and developed this relatively easy build..........even a poorly made example will run. It is a proud moment for both the student and the teacher when they complete and run one of these. Check the video to see one in action.
Students will apply a series of fundamental engineering skills using a variety of equipment and machinery to work with precision, this includes lathes and milling machines. They have the opportunity to either work independently from a step by step guide or if unsure about a process can ask a friend or teacher for guidance enabling them to learn a new skill. Students aim to recall previously learnt skills and apply in a more challenging situation, they have to use a metal lathe to drill to a precise depth, parallel turn to a specific tolerance, and......... they will also learn how to cast aluminium. This project is a skills challenge and a massive confidence builder.
Future learning objective
I am intending on expanding this next year to include scientific calculations.
- PSI Vs RPM graph
Step 1: Students Work
Step 2: Fly Wheel - Making the mould
- Scribe a Ø70mm circle on the Styrofoam using a divider or compass
- Cut out with a coping saw then use the disk sander until round
- Collect a 'runner' and cut a V groove in the top then flatten the other end on a disk sander
- See teacher to stick together with superglue.
