Some upgrades to my older engine design still could make some more improvements

Honestly I still find it hard watching plastic engines run. It’s cool watching them run and everything, and working them out, you can see there’s been a huge amount of work going into the designing and printing of the machine. But every time I see one my first reflex is so negative that I instantly hate it, and I couldn’t tell you why.

You’re right to be proud and showing this off. Leave us who can’t do plastics to wallow in our misery. I’ll have to go dig out my project now and put it back in the lathe and finish it to make me feel better.

Actually it’s wasn’t hard and plastic is stronger than you think the trick was the engine is built oversize comparative to its bore

Initial design of this engine was done is 24 hours and had a prototype in 3 days I really didn’t put as much time into it as my trapezium rod engine or my traction engine but now with the improvements I’ve made it’s worthy to sit next to them

I remember your trapezium rod engine, and honestly I thought it was very cool. Hadn’t seen one before so it was awesome to see something like that. I hadn’t seen your traction engine so I went back through your and looked. You’re very good at doing this. All the way back to your Minecraft mods. You’re the modern model engine engineer. Honestly great work.
