Coal Origin v2.0
Previously, I had made a stack of 3x10 kilns and named it Coal Origin because of the "similarities" to the Blue Origin rocket shape:

Some of you wanted "MORE!!!", and to be honest, so did I, but it took a lot of material farming and a trip to the Ashlands pre-queen to get myself the ability to portal ore and some Ashwood, so there was a bit of a delay. I'm doing a normal drop rate/hard combat/build cost enabled run at the moment, so this took a bit of extra time.
I now present to you the next iteration: 120 kilns, 40 smelters, and 40 blast furnaces!
As before, the kilns all drop the coal straight down to easily collect at the bottom. If you thought it was a nuclear reactor before, the orange glow from these puppies looks a lot cooler off the marble :)
The smelters/furnaces all drop their ingots onto the 67º slope of the plinths, which transition onto some roof tiles (a single 45º piece which is barely visible - mostly there just to prevent a hard corner which could catch the metal prematurely - followed by two 26º pieces). Once it slides down the roof tiles, it bumps into a half wood wall that is only sticking up halfway itself, so basically a quarter wood wall, which stops it from launching further. In case an ingot manages to get stuck on the tiles (happens rarely, a lot of the build went into limiting that), there's a wood gate on the side to let me enter and check for loose ingots. I started with the gates in front but would leave them open and forget about it, which would result in ingots getting strewn about.
The corner stair pieces were a pain to line up at the top, but I'm pleased with how they turned out!
Technically this is modded, but all doable in vanilla as well. The mods mostly helped with things like making placement easier by adding snap points or increasing the hammer distance, but it could have all been done without that if I was willing to spend the time on it :)
As always, happy to answer any questions, encourage comments and constructive criticism, etc.
