Jim, thanks, and thanks for moving this to the appropriate place!
I already made a complaint earlier today, after talking to the pres of my condo board who said he was in favor of doing that as the noise has also been driving him crazy for months.
However, I'm not sure how responsive the police will be, so I may yet get a chance to start fresh with gentle persuasion. The downside of it is that I would have to either leave a note, easily lost or ignored, or basically come out and accost him, as I have no idea where he lives or any other way to reach him, and being three weeks post-op I'm just not that inclined to take on a possible confrontation with a stranger.
You are right that if he's basically a decent human being, he may agree to "roll away" from under my bedroom window, at least for a month or so, out of sympathy for my head!
