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!
