[TheForge] Re: Ralph, Mike and their toys (Was: OT Threads ?)

If we're talkinig about governors through the centuries, why not take the roman approach and use a few pretty girls in skimpy costumes, captured (dramatically) after some battle or other? They could take turns keeping the rpm's constant and fanning the smith with palm fronds.
   
  Just a thought.

Okay, so what's the big deal about a speed control? There've been so many 
different kinds over the centuries I'd think it's just a matter of picking 
one and adapting it.

For instance the wind flappy gizmo governor would be a piece of cake to make 
and adjust. Pick or make and attach a fan, blower, bicycle wheel with 
playing cards in the spokes. Attach a vane in the output airstream with a 
control arm to the throttle and a return spring opposing it. The higher the 
RPM the more force backing out on the throttle, the lower the RPM the more 
the return spring turns it up.

If you wanted to get creative and perhaps a little artistic about it you 
could set the governor up with a float in a section of clear plastic pipe. 
Attach the pipe to the water pump and let the head pressure from the pump 
determine the height of the boyancy actuated throttle position system.

You could set the same thing up using the oil pump but it probably wouldn't 
be as scenic.

Okay, this should be simple and even maybe practical. Use a vacuum actuated 
diaphram, or even a pneumatic cylinder.

Basically just pick the RPM sensitive device and build in plenty of 
adjustment till you get it tweeked into tune.
