Yes, I know about that way) I prefer to create a separate file for each (reasonably complex) part and then combine them all in a master file.
Like Reitwagen_wheels, Reitwagen_engine etc.
By “detective” I mean that there are so many variations of that mechanism that have been built since 1885. And I do not own a copy of that bike so I have to rely on these pictures.
Sometimes it is just too confusing to separate mistakes and “interpretations”.
I have to say that this project is big — for me at least. Gonna do something way smaller after this. Maybe it is gonna be that ball Wilson from the Outcast movie. Just to flex some muscles.
And then — another big one.
Oh, and the polycount (no engine involved):

Looks too fat I think. Trying to reduce the number by cutting off all the parts of the bolts I can spare.
