	* ~~Half of dimension~~ specifications complete, see [[Steam Engine Build Instructions]]		* Dimension specifications and CAD drawings are complete, see [[Steam Engine Build Instructions]]
			* Ready for fabrication and prototyping

			Note that in the process of creating the current design, a number of problems have been discovered [http://opensourceecology.org/wiki/Steam_Engine_Reviews/Arrowhead_Bump_Valve_Summary]. Some of these are simple to correct, others may require substantial design changes (valve design, for example).

			Other designs are being considered including one based on rotating valves controlled by stepper motors [http://opensourceecology.org/wiki/Steam_Engine_Design/Rotating_Valve] and a return to the Ball Bump Valve Design similar to what was used in the White Cliffs Solar Installation [http://opensourceecology.org/wiki/Steam_Engine_Design/White_Cliffs].
