All but the middle block of this puzzle went pretty smoothly for me. En route to the problematic parallelogram I was entertained by the clues "Put away the dishes?" for the old standby EAT, "Like privates, often" (PIXELATED), and "Things waiters wait for" (TIPS).
I'll ADD that there were a number of nicely tricky clues as well, including "One who's 60-something" (DSTUDENT), "Wednesday, e.g." (ADDAMS), and "Part of a pound?" (STRAY). I also enjoyed NEATASAPIN and FLAMBOYANT.
Breaking into the center square took some trial and error. I must have put in and taken out GABLE five times. For some reason, AMBIT, GELDS, and NEMEAN didn't leap to mind. Something about the clue for BEETS threw me off, too. I was thinking of a more general natural food coloring source. It also took me forever to think of music for 41A. "Stop playing" symbols (RESTS) - AFLAC that will surprise no one who knows me. It seemed like something of an ODDITY to have both AMBOY and AMBIT in the same puzzle.
NODEAR seems difficult to clue well, if you're going to use it, and probably not worth the effort. CAVER, COS, and ONENO win no prizes from me. And, thank heavens Mr. EADS invented something, otherwise puzzle constructors would have had to invent him!
