What kind of mates should be used in order to have a rotating camshaft push the valves down the valve head? I made the Aykut Dana, V12 engine tutorial but i can't mate the vlaves the right way!
I'd use a 'cam' mate between the cam and its follower. Bizarrely, if you've used the cam design tool in SolidWorks, you may have great difficulty.
I have a working cam mechanism here:
Engine V Twin
(you need to 'float' the components to unsuppress the mates).
If you have difficulty putting a cam mate on a cam, let me know.
