Hey Capt,n I have two cases comming from Keith. The crank is easy now that I talked to him. Cut one end of a crank off flush with the counter weight. Bore a hole into the counter wieght to accept the other cranks end. Cut another crank down so that you allow for and have a flush fit when pressing that nub into the bored hole in the crank. Line up the cranks so that you are opposed 180 degrees and both rods will be at TDC at the same time. The counter weights are ground flat so when you pair them up all you need to do is tack weld them together in a couple areas. I will figure some way to make a jig or some setup to indicate them in as close as possible. Keith indicated to me that if you were off a bit it will not make a difference. I may for safety sake drill the front journal area and pin it. Keith said there were some that would walk and get out of line when welded. My welder friend said he can do the tig welding no problem and keep heat to a minimum too. I may have to try this before I tear down my machines to move them to my new house and shop. We will see. I am trying to finish assembling my new Carden 35% Edge now before I move. A few more nights wiring and a little time with the spray gun and I will be set. Maybe!!
