Inline Twin Engine Ep. 8

A number of components are finished and I felt it’s time to assemble what I have. I don’t want to get too far ahead of myself, making parts. If there is a problem, it would be easier addressed now rather than later. And it’s always exiting to see an engine taking shape…

A plug is inserted in the camshaft bore to close it off on the back of the engine.

The crankshaft is finished up on the accessory end with a small diameter shaft extension.

To give you an idea of the size of the engine, here with yours truly.

I’m very pleased how the engine has turned out so far. Everything is fitting together and works the way I envisioned it when I designed it. I haven’t discovered any mistakes in the design (yet).

It’s very low friction. I hope this will materialize in the running characteristic of the engine. I tried to take a short clip of me turning the engine over to demonstrate.
