Almost there!
Fire extinguisher and fire blanket are hanging on the left of the desk; propane is in a mini wooden lean-to outside and will be piped through the window to the right (I didn't want to pipe through the wall as I'm planning on detaching the hose after each session). Make-up air is from the open door/window to the left, exhaust air vents up and behind me so only one bend.
Tackling glass storage tomorrow and maaaaaaybe getting some torch time! It's been two years... Not as long a break as some people, I know, but still!
