Thank you.
Now time for digestion and coming up with a plan for manufacturing - - - grin!

Ajoeiam - I am going through the same exercise.
My first thought is to machine the rotors slightly oversize, then run them together with abrasive in a purpose built fixture with adjustable pitch centres.
I used a similar process to make cheap steel gears fit well enough to make oil pumps.

Very nice. Good luck on the start up!
Maybe I missed it, but what did you end up doing for oil lubrication pump(s).

I initially thought of putting an oil pump to lubricate the cams then instead I filled the cavity of the camshaft with good grease for bearings , the camshaft cover closes and hides everything
To prevent the intake valves sucking the grease I put a seal on each valve stem.
The crankshaft turns on bearings and the oil sump is filled with oil.

I have been following your progress with admiration. Wonderful work.
Now that the small-scale test version is complete, you can start on the 1:1 version. I will be happy to build the chassis, and we can be the envy of the country.

Foketry,
OOOHHH!!!! Wonderful! - I just love to see a "new runner".
CONGRATULATIONS on an excellent result for all the time and hard work that this obviously took.
Maybe we can fit in my Moto Guzzi chassis? - But maybe it is just too long...

it would be a great idea, even a friend of mine proposed this to me, we could be 3 to collaborate on this project ....
A few months ago a replica of the Bugatti T 35, 8-cylinder straight engine, was sold at auction in California for $ 234,000 (manufacturer Pur Sang, Argentina)
I'm joking , if I had a car like that, I would never sell it
