This part is still under construction as is the rest of the engine. However this was a nice juncture to show progress and direction I'm headed.
Plan to have working valves and springs made of cardboard. Been working on a design which actually has "spring" action for opening and closing the valve.
More on that later. Still need to make the cam, valves & guides, plus the rocker arms.
enjoy all the segments from the beginning to show the evolutionary build.
