WOW! Are you a professional CNC operator? Or just have one for personal projects?
Also who makes those hydraulic fittings?

Thanks a lot to everyone...
@Bo Wallen: i'm from Florence.
@avel: i have been a manual/CNC machinist (mill and lathe etc.) for several years and begin to work with a lathe for hobby when i was 13 thanks to my father's mini lathe. But the work you see in photos is made by my personal manual lathe and mill (more heavy machines). The hydraulic fittings are made by SMC corporation in Japan. They sell all over the world and in the USA is more simple to find and buy it than in Europe. In Italy instead is a big problem... like for everything! Price is crazy!
You can buy it from www.smcpneumatics.com or even on Amazon. Search for "smc miniature fittings M series".

A few minutes and i'll send other photos...

See you soon!

I'm here again with the model of the chain/shoe....















And the beginning of the cylinders construction...







The first prototype of the hydraulic motor...























Goodbye!

Hi everyone, thanks a lot.
The motor is of the orbital type and it has 7.8 cubic centimeters of capacity. This is the first attempt to build it and the torque is too low even if in general it works well. I have now to receive the special profiled rotor-stator coupling from an external laboratory that work with CNC mill and reassemble the motor for the tests.
Then i make a video....

Very nice machine work.

You are displaying great patience and bravery for making the hydraulic rotary manifold and making hydraulic motors for the drives.
