I borrowed a slick little Festool circular saw and guide to make the cuts and it worked beautifully but for one unpleasant surprise: an embedded steel plate was along my cut line, resulting in the rather pricy saw blade losing a tooth upon impact. I set the depth shallow for a clean cut on that short stretch on each piece and cut through the steel with a better-suited (if less precise) jigsaw. I’m pleased with how these pieces came out, and they are 1) much easier to move, and 2) a bit lighter than I expected.
