Constructor's CommentsSometimes I think of an idea for a puzzle that necessarily implies an ambitious grid and let it pass blissfully from my mind. But SIX CYLINDER(S) kept bubbling back to the surface, and I figured a seven-theme puzzle could work if a couple of the theme answers were short (SPOOL, CIGAR). No one likes excessive grid wrangling, which can grind you down until you start thinking, "You know what? NENES isn't such a bad word."
Fortunately, David held the line on NENES (and a few other unsavory bits). He even suggested replacing LINAGE in the NW corner with OWNAGE, a lovely alternative that wasn't in my word list. David FTW! And not the first or last time. . . .
