That was me Dave,  Paul L published plans and photos of a dyno that was 
based on one originally built by Everett Hatch.   It may be the one 
still in use by Power Sport today.  It is a simple device that measures 
reaction rotation on a bathroom scale.   You can see PowerSports dyno 
on their site.  You can visit the ACRE site to see more.

The plans and photos show the dyno mounted on a trailer for towing. 
Mine will not have wheels but will be bolted down to the shop floor.  
If you wanted yours on a trailer then the costs would go up some.  
Somebody (else) (like Ed Klepeis)  ought to go into the business of 
making these as there would be interest throughout the home built 
scene.    If three or four went together  and ordered at the same time, 
Ed might get interested.        Jerry
