My FB710 (900 lbs) sits on 2x4 douglas fir and plywood base, material from another machine's shipping crate and built to fit a narrow-fork pallet jack.? I think you saw the pictures I posted in another thread of the base.? Douglas fir's parallel-to-grain compression strength is about 1700 psi (source: engineeringtoolbox.com) .? After 1 year, the base has no visible change or deformity.??
