I bought plexiglas at Lowe's & my DH cut the hole & countersunk screws that hole adjustable legs. He cut with a 'saber saw' , but the plexi edges melted cuz the saw was "fast". He says if he could have lowered the rpm's or had a metal cut blade, it would have been easier. But he did a fantastic job and I have less than $25 invested (labor was free!)
