" However, the padding was a pain to drill through" Just get a piece of metal tubing (3/8 in dia worked for me) and use as a punch to make a hole for the drill to get to the table and not the pad / carpet. Russ
Reminds me of when I was an apprentice carpenter. I had to install some hardware on a door to an office. Part of the hardware installation involved involved drilling through newly laid carpeting. As soon as the drill bit hit the carpet pile, a line appeared all the way across the floor. You would guess correctly that my boss wasn't a happy camper that day. By the way, I kept my job.
