Low Temperature Differencial Stirling Engine

[Stewart HartParticipant @stewarthart90345]

A few weeks ago a friend from the club said he was trying to help a young engineer with a school project, a Stirling engine, and he was struggling to help could I give him any advice.

Now I must admit that I've been trying to avoid Stirling engines as I know they are tricky beasts, but I thought our resident expert and curator of the Stirling Orphanage Dave stilldrilin was just the man to ask so I acted as a bit of a go between, and then it happened I got infected with the Stirling Engine Virus. I loosely followed the drawings on John Tom and advice and encouragement from Dave.

As I feared it was a far from straight forward project but after many false starts and reworking I got it going.

 

I'm pleased to say that our young student engineer got his going as well

So a big thank you to Dave for all his help.

It's great to encourage youngsters to have a go at making things.

This is one I designed that can be made from easily obtained materials.

Hi Thor

Yes it is a CD fly wheel fixed on the hub with supper glue.

It can be tricky stuff Steve, I once had a bottle of superglue stuck in my clenched hand, I got out eventually

Are you sure it wasn't a ten-bob note?
