are cam mates a joke being played on us or are they supposed to work? i have 16 cam mates in this assy and am constantly fixing them. seems like the only thing reliable about cam mates is their unreliability. some repeatible issues: when assiging a cam mate to an adjacent mated rocker, that rocker flips its mate. real handy. another issue is simply rotating the camshaft to check the rocker and valve operation causes cam mates to flip. animator really screws up the mates. i have tried using a rotational motor and that not only runs like a molasses, but flips the mates as well. my client would like to see an animation (as would i) but the damn thing will not stay together for even 1 revolution. any help would surely be appreciated.
