Hello Chaps - & Chapesses!
I have been tinkering with an engine model and have managed to arrive at a possible solution for driving cam followers and valve gear from a rotating cam. My solution is not elegant or precise, but it works. I wonder if anybody has a better solution to the problem? For example, can you use Physics to keep the cam followers running on the cam? I know I can duplicate motion for some of the engine valves, in other words I don’t have to make profiles for all the cam followers, but it would be nice to make it a little better.
I should appreciate any help, criticism, thrown brick-bats or whatever to find a more efficient solution.
