I'm not sure if the this is the right place. I've got an unmachined flywheel casting which was intended for a Stuart 1/2hp open crank engine, but this isn't going to happen now.
Its 12" dia, 2 1/4" wide, intended to go on a 1" dia crankshaft. 6 curved spokes, heavy rim, weighs about 20-30 lbs.
Its in Worcestershire, and is far to heavy to post. Anybody interested at £50?
