[TheForge] new shed design and other ramblings

[Bruce Freeman]

Terry,
I'm picking up on the 3-phase power requirement.
You use an engine to generate power which you then use to power motors.
Very convenient, but not efficient.
How about a modification of the old line-shaft idea.  Run an engine
and power the tools more-or-less directly from it.  I know this
conjures up visions of 4" iron shafts and bearings, and big flat-belt
pulleys everywhere, but that was only one implementation of the idea.
You could use scrap driveshafts from trucks or cars, and use the
differentials as variable-speed output points.
Just brainstorming here.
Best of luck.
