I am looking to move into a new shop. It is the second floor of an old industrial building, with wooden floors. Heavy beams, adequate floor ratings for machinery, etc...
However, the building has shifted substantially over time and the space I am looking at has about 6in of slope over 20ft.
What I would like to do is run scribed/levelled sleepers on top of the floor, and then put down a new floor directly on top. Screws for everything as it will potentially need to be removed after a few years.
I am planning on 12in spacing.
That's the background, the question is what kind of floor material should I put on top of the sleepers that can support a basic knee mill? That's the heaviest thing I'd want to put in there, and that's about 500 pounds per square foot over around 6 square feet, once I account for the biggest work I might get up there. My understanding is a 9x42 bridgeport is about 2,400 lbs and the base is 24x36.
I assume 3/4 plywood is going to get crushed. Is the beefier 1-1/8 or so subfloor material adequate for this? I'd plan on putting a thin steel plate under the machine itself, probably 1/4in just to keep any feet or levelling shims from sinking.
