There has at least been some progress since the “Paralysis by analysis” post.
The engine is now actually in running condition!
A great milepost for the project.
Those raw brass parts in the PBA post looked quite difficult to get together, but in the end I was able to assemble them into a functioning mechanism. As a self-trained model engineer I had to go real slowly. But even then I was not able to achieve standards anywhere close to professional engineers. But the rubber band drive is quite a good idea for amateurs. In theory, this is a very crude concept. But it is very forgiving to engineering sloppiness, so I think the engine runs far better than it would have done with a gear tower transmission.
