Hi Ryan,
This indeed was made from old hardwood oak. You know, solid 3/4 of an inch tongue and groove. The photos don't exactly show the glue up, but there are four quadrants at diagonals pointing to the center. The solid wood is only about nine sixteenths of an inch thick, and it is screwed to a 1.125" MDF substrate to give it thickness as well as stability.
The copper banding is inset so it is flush with the hardwood surface edge. By that I mean I used a my router table to spin the assembled top against a spiral bit to remove a fat 1/64 of an inch for the copper to set into. Where the band meets itself around the circumference I used a piece of extra wood edge banding to wrap around the table to determine the length that I needed to cut the copper. I left the copper a little long so that I could trim it to the exact length needed. I used spray contact cement, like what you use with laminate, to hold the copper banding in place. Then I trimmed it to length after I drilled the holes for the nails, installed the nails, and was content that the banding didn't compress or expand during this process. Thanks!
Regards,
Hutch
