I have it mounted on an old coffee table, put a 1 X 12 board on top, leaving it stick out 2 inches on each end, then placed a 4 foot piece of 2 inch angle iron in the center of the board, then ran 4 foot long all thread bolts down the edges and cranked it down tight to another piece of angle iron under the coffee table. With the card board, many times the arrow slides into one of the corrugated holes of the card board, so it really doesn't tear it up a lot.
