I have put the triple expansion steam engine build to one side for a while. There are many parts made over the past year, but still a few to go, and I am taking a rest from it.
My modelling club is conducting a competition to build a Stirling cycle engine, and I have decided to make an entry. It is the coffee cup engine by Jan Ridders. It is an annual Stirling cycle competition. I made an entry last year, but I couldn’t get it to work. So I am determined to make this one work.
I am also using the Koffiekop engine project to become more familiar with the CNC machining processes. So I am making as many components as possible using CNC. For simple parts this often takes longer than using a manual process, but my CNCing is definitely becoming faster and easier, and crashes and tooling breakages are now rare.
The Koffiekop is progressing well, and I will post some pics and maybe a video when I get it working.
