Your monster of a table is going to be HEAVY, so I strongly recommend moving it to its final destination in two pieces–lay a blanket down in your dining room, put the top on it upside down, then the frame upside down on top of that. Attach a couple 2×4 supports across the frame for good measure, then begin the frustrating process of centering the frame on the top. Once you have the top centered, attach your brackets–I did two on each end and three on each side.
