Reverse engineer some tech form the WWII. In BMW style.
One of my favorite objects is this R71 form 1941. It fought the war (on the wrong side of history) and was converted to civilian use, later on. However that is not why I like it. I got it in in 2007 and proved to be a fun motorcycle. Not entirely made of steel though. Part of the accelerator was made of a unidentified (unmarked) metal. Whatever it was made of, it crumbled to dust in my hand during an inspection, making the bike unusable. There is a wide range of new spare parts for this kind of historic bikes, and they don't come cheap. Buying a new accelerator assembly was an option. Regardless of the price tag, if you like to fix things like me, you rather spend 2 or 3 times more, for something home made, that will be ready much later and carries a chance of not working as intended. Here you can see the reversed engineered component that was 3D printed in brass by "i.materialise.com" (no affiliation).
Here you can see how this little and crucial part interact with the system and how brass look soo much cooler.
Next in line is a different component of the accelerator assembly that cracked recently. I will add that info as soon as I address it.
On going project...
