Hi lules
do you use a hardened shaft? i belive the needle bearing will wear an unhardend shaft quickly.

Those are great looking cams. Good idea with the square👌.
I used a kind of fork that matched the lobe of the cams to adjust the cams. Your solution looks way more accurate.
How do you machine the cams? Any pictures from the setup?

Regards Michael

Hi Michael
here is my setup, Now I am milling the intake cams
They are obtained from ground bar, C45 steel
The most suitable steel would be 115CrV3, which I purchase from GHW modelbau in Germany, in Italy I cannot buy small quantities of this steel, only tons , this steel is easy to harden with high hardness in water
