Four Hot Air Engines running in the Garden

Running my four model hot air engines in the garden on 27th March 2023, the best weather we've had so far.
From left to right the models are Heinrici, Rider Ericsson, Robinson and Bremen.

A beautiful collection of hotair machines. You probably made good use of the good weather at the weekend. I could watch the machines for a long time.
best regards

Nice collection like the Bremen on the end

Amazing collection !! What are you running for coolant in the Rider Ericsson?

Thanks Will, I use 4life ( 4lifecoolant.co.uk/ ) so that the cast iron cylinder liner doesn't rust. I have five litres and share it between my model engines. After running I drain the coolant back into a cheap stainless steel thermos flask.
