You reminded me of what we did for a large worksurface in our community shop some 8+ years ago when we were all moving in... at the time they were doing demolition to a local Mall and had huge slabs of the parquet wood flooring for anybody to haul off. It was rough and jagged, had lots of nails and big staples in it and was probably 5/4" thick altogether. We grabbed a piece with as many good edges as we could find and not much larger than we needed, then I spent a morning grinding off all the nails and staples that could not be pulled out, and then we put the monster on a huge table saw and trimmed it to size, built a base for it, (also out of scrap from the same demolition) and still have use it to this day, and it's taken a lot of abuse over the years and still looks great and is as sturdy as ever.
