Thanks for kind replies

.
Whole project is a sum of compromises, as the previous one was.
In practise one could say: Use the materials, that you have available, and the tooling you already have. Be it modest or whatever, make it to happen; take the most out of it.
Philosophizing aside, at this stage, when looking at the current engine's design, crankshaft would have less stress, if the flywheel was located inside the crankcase, as it is on Hoglet(or so I assume, based on the photos, that i've seen).
For some strange reason, I just had to do it on different way

.
Same kind of oddness was noticeable, when I tried to make a fastening part for the piezo unit. I failed four times making it

. Then I just stopped, and thought: 'this will not be a part for this project'.
So back to an ordinary breaker points -schema. Lo and behold: parts for that were a lot easier to make. In fact, they are now ready to use.
Anyways, the progress of this project is in halt -stage for a couple weeks, due to renovation on my apartment.
I'll travel away, but try to lurk as often as I can.
