Two cylinder questions
(1) Has anyone made an S-IVB that is actually 6.6m in diameter, instead of the 7m of the official Saturn V set, which is also used in all the Saturn IB MOCs I've seen?
(2) A ways back I saw a picture demonstrating cylinder creation techniques and their size in studs and mm. I stupidly didn't save it at the time. Does anyone know what I'm talking about and can they post it? (It was a top down pic showing, for example, the brick-with-4-studs plus plate or jumper plus tiles for 8ft/2.4m, brick-with-4-studs plus two plates plus curved slopes for 10ft/3m, etc.)
