The crew continued conflat installation on HAM-8 until they ran out of parts. (The only remaining cleaned conflats-feedthroughs are for the one-arm chambers.) Doors were replaced on HAM-7/8 to clear the way for HEPI plumbing work. The west door of HAM-7 had some worrisome-looking spots on it which were scraped off with a razor blade, FTIR-ed, wiped down, and re-FTIR-ed.
