The easiest way for me to get access to the space behind my bathroom vanity to run some electrical wiring will be to cut a big hole in the sheetrock. It seems that if I cut the vertical lines down the center line of the 2 x 4 studs on each side, the panel will be much easier to reinstall. It's a no-brainer to cut a hole in sheetrock with a sheetrock saw, but how can I cut just the 5/8" or so of sheetrock that is against a stud?
A circular saw would work, but the sheetrock would probably destroy the blade. A MultiMax tool might be a good idea, but I don't have one. The ideal solution in my mind is a Rotozip, but I don't have one of those, either. While I do have a router, it's quite large and would be hard to handle on a wall like that.
How you you professionals do this, or is there a better way?
