The highboy videos helped me too. My only problem is he has the eye of the chickenhawk and I have the eye of the chicken. That is why I made a toolkit to help me do my timing. (these damn bifocals)

Now as far as the PTX. Don't you dare give up. You don't want everyone to think an old wingnut can do it but a ground pounder can't do you? It took me a while too to get it perfect. But it was well worth the battle. My suggestion is to remove all of your dies and install the power measure in position 4, and time and tune it there. That way it can turn the hopper without hitting anything else. That will take a lot of frustration out of the process. Things work a lot better when we are calm and cool. Oh, remove all tools like hammers be for you start. And install a curse jar. And put a buck in for every bad word. You will now get a perfectly operation power measure and enough money to buy supplies.
