My first reproductions were, of all things, 80mm bore pistons! It took me about ten years to finalize the design with no less than four different prototypes. So, sometimes, making a reproduction is a long-term project.
Since then, I've reproduced lots of different kinds of parts. Some for the Okrasa engine, some for the Karmann Ghia in particular, and, well, just about anything that's needed that can't be readily purchased.
Here's a partial list of things I've reproduced so you can get an idea of the things I can reproduce for you, too.
When I get a little more time, I'll be posting photographs and descriptions.
I can make other things if you want to commission something.
