I "need" (as defined by wife, not me) to move a 1st floor light fixture about 56 inches. OF COURSE it's across joists, and OF COURSE it's on the 1st floor so I don't have access to it from above.
Is this as ugly a procedure as it seems like it must be, or are there tools and/or techniques to make it less painful (primarily defined as not messing up the ceiling byond the existing hold and the one I'll need to make)? I am assuming I have to drill through all the joists between the old and new locations, so some type of extended drill bit seems like a bare minimum. But 20+ years of DIY home repair/remodel has taught me others often know a "slick" way to do a given task, and I'm hoping that's the case here (although the geometry and physics of the problem certainly don't seem to leave much wiggle room for such a solution).
Thanks in advance for your input!
