so, now it gets messy! heat gunk everywhere!
from the look of the diagram in the book you’re meant to put all the pipes parallel. but i thought i’d spread them out a bit since they’ve got a bit of give and maybe that’ll spread the heat a bit more. or whatever. do let me know if i’ve done it wrong.
they say to put a 1mm layer of gunk on the surfaces. that’s huge! i spread it much thinner than that and i still ran out of gunk before i’d finished.
