Chris's Marion Valve Winding Engine Complete
« on: December 30, 2019, 09:04:55 PM »
Hi all,
The Marion-valved winding engine is complete, very happy with how it came out!  And thanks to all that helped along the way with tips/ideas/etc, much appreciated!

This engine is of a mill-type twin cylinder, but it uses the same valving setup that the Marion Steam Shovel Company invented for their slew/crowd engines. It has a central valve that controls both the speed of the engine and the direction, so one lever allows for control of forward/reverse/throttle without the use of any external linkages for the reversing - it uses a special two-level slide valve and four ports in the valve face on each cylinder, and swaps the steam/exhaust between two pipes in the central control valve. There is a section in the build thread that shows more detail on this.
Here are some pictures of the completed engine:



and a video of it running - self starts well in both directions and the throttle lever controls the speed nicely:

Thanks Zee! And yes, work on the Stanley is about to start. Getting the plans ready, and drawing up some of the holding fixtures for the main block.  So please have your attack elves stop looking in the windows and saying Weeellll?   :Jester:

 :pinkelephant: However... ;D...being an engineer yourself, you would understand my need desire requirement for some deadlines.  ;D

  :embarassed: I say this with, not insignificant, trepidation that I'll be asked the same question at some point too soon.

One of the airplane builders here in the Airpark, when asked "when are you going to get your airpane finished" always replies: "On Tuesday" He just never says which Tuesday!  :lolb:

PS: Your engine came out great Chris. This has been an enjoyable build to follow.
