After seeing the redryder engine, it seems pretty apparent that a ton of crete may not be necessary at all.
been altering the frame design a bit
http://listerengine.com/coppermine/displayimage.php?album=random&cat=0&pos=-541(this is a rough sketch of concept only, dimensions are not to scale and placement maybe altered)
with the latest evolution, i have moved the genhead off the subframe so as to keep the engine in the center of the subframe, and thus
keep the centerline of the crankshaft centered in the cradle.
with the genhead base plate mounted to the top of the cradle the weight of the generator works to bias the
stronger countertorque (anti torque to the english) of the power stroke,
sorry for being a pirate and taking the discussion back to the original topic
one pirate to another i guess
still playing around with idea's and design alternatives here
