Can anyone suggest the best way for me to cut an access door (maybe
12-18" square) in the back panel of a large worksurface? The panel is
..5" particle board with some type of laminate like formica.

I know I can just drill a hole, then get a saber saw and cut the hole.
But I would prefer not to leave a hole. My hope is to be able to
"re-attach" the cut out part in some fashion after I fix the phone
line and make it look as nice as possible. That is, (a) the thinnest,
straightest possible cut, (b) the least damage to the surrounding
laminate, and (c) a good way to re-attach it afterwards.

Thanks
