Dave, the wireless table in the HUW is not 1/2" plywood. The table frame is 1" angle and the wood plus linoleum sits on the upper face of the angle on the bottom to flush with the top so is 7/8" thick combined. 
 
7/8" table, plus two strips (each 1/16"), plus the 1/8" foot, plus 3/8" for the nut and lock washer and it means at least 1-1/2" bolts.
