porpoisefathom: Reversing is via a lever-operated slip eccentric similar to that used on Semple engines. The valve eccentric is not fixed to the shaft. It is free to rotate, less than 180 degrees. The shift lever causes a spiral slotted white delrin sleeve to rotate the valve eccentric on the shaft the appropriate degrees to reverse the engine direction.
After repeated viewings, i can safely say that even though i have built race engines for a living and being a motor mechanic, i have no idea of what the hell u are talking about. Steam engines run on a very simple concept, yet your explanation makes the concept overly complicated. More research on the exact operation is required by me.
@AUTURBO6 It may help if you google "balanced slide valve" to get an understanding of the problem being addressed. Solutions have been patented for well over a century but it all seems weird until you know about the original problem. Originally it related to high pressure on the valves causing problems when changing directions from forward to reverse with the common hand lever.
whats your reverse mechanism?

Wikipedia has a nice description of how a D valve works. Just search "how does a D valve work. Includes an animation
