I wish to set up my Crossley crude oil engine. As it has a short base.it was originally on a tall concrete base.with another to support the outrigger bearing. The flywheel weighs about 2 tons! Some like to make a rigid steel frame that takes the lot. What I’m thinking is a box base so that the flywheel clears the floor,and a separate rigid fabrication that will support the outrigger bearing. I can’t think of any reason this shouldn’t be alright. Any comments welcome.
