There is this guy in my area (Worcester, MA). His nickname is "The One-Armed
Bandit"; I'm sure you can guess why.
He used to use an ashtray as a bridge until someone made him this steel
free-standing contraption thing that he put his cue through. He shoots, then
lifts his cue off the table and it slides down the shaft very dramatically.
Anyways, He's a very good player and I asked him if he ever played in
tournaments he said he couldn't because they wouldn't let him use his steel
contraption thing. Wouldn't that be legal as a mechanical bridge???
