This is an original design, borrowing different elements from several examples found over the years.
The main feature is the dual spool valve similar to an old Weeden toy engine I had. It is self draining through the exhaust, without need for drain cocks.
I am currently fine tuning the design and developing the CNC code to make the individual parts.
I also have other variations in the works utilizing unique linkage to control motion.
Planned releases are:
Finished Engines
Pre-Machined Kits just needing hand finishing and assembly
Lathe and Drill Press Kits with milling machine work done and holes spotted
