Hello, I am Jan from southern Germany, long time lurker and reader here.
Just found a topic where I can actually contribute something useful maybe, so I decided to get a bit more "active".
About me, I am an engineer, working in a small company on the other side of the border in France, mostly on older / historic engines nowadays. A lot of Mercedes, from Diesels to things like the M198 "gullwing" engine with its mechanical direct injection system, some English and Italian engines, quite a bit of Porsche...
Being a small company, I do everything from CAD work to cleaning the machines, most often 6 days a week, so I don't have a lot of time for this hobby sadly.
I am working on a 1:3 scale Bugatti Type 35 engine for quite a few years (and it will take a few more, see above). So far, there are no actual metal parts made yet, but about 80% of CAD and drawings done... And a lot of parts printed in plastic, to have something to look at (3D-printing can actually get a kind of hobby itself).
Lots of things to learn, for me!
