Gentlemen,
I have documented this build elsewhere and it's a lot of computer time doing it twice so I'll hit the high spots for everyone.
This project has been in the wings for quite some time. I had acquired a set of Morton radial drawings many years ago and stashed them with my other drawings in the file cabinet with the idea of building one someday.
Well someday is here. After going over the drawings there were quite a few things that I didn't care for so it was off to the drawing board to make almost a compete redesign. The only dimensions that stayed were the bore and stroke and the diameter of the crankcase.
Some of the numerous changes are: moving the lifter/pushrods to the front of the engine, utilizing roller lifters, making screw together cylinders and heads, using a pressure/scavenge oiling system, moving the carburetor from the crankcase to the rear of the engine and changing the distributor from points to a Hall effect type.
The first set of pictures show the finished main crankcase. It was cut from a block of aluminum. As with my other projects the detailing was stepped off by hand and then finished.
