Single or Dual Pattern Cam

Ahhh, now the Carpenter/ Drywall guy digs it! Thanks Brother! Basically, like I Can, AND HAVE, literally, Raised a Roof, it still has to have " Legs"! But...I just still caint get it.. ain't Max Lift the pointy, narrow ( like my head..) of the lobe?
Yes. Imagine the cam grinder MOVING the whole lobe on the core so the peak of the lobe is higher than it was. Of course that also means the base circle will be "lower" necessitating longer pushrods. Get it?
