Part 6 (and 7... and 8... and 9...) of FurnaceClans is up!
Really, they're all Part 6 in my head, but due to mechanical issues I split them up. They're about 15 minutes a piece, roughly. They cover the magma loader rebuild, the OMG trap design and dig, and the minecart magma loader for the trap.
Part 6: Overview of the fort status, the new magma loader tested, and the design and build of the OMG system.
Part 7: OMG design review
Part 8: Trap dug, second/third level shown, dry run testing, and Cavern 2 sealing for Impulse Elevator straight shot.
Part 9: Design, Dig, Test, and activation of the Magma Loader via Minecart system.
Edit: Goddamned that lost cart bug is annoying. Just lost another one in the magma loader. Drained the system to see if that would cure the cart showing on stocks and hauling but not available in reality and spamming the crap out of me with stockpile requests. No Joy. The thing is just... eaten. Wonder if I'd have the same problems with Steel Minecarts... maybe it's something about iron?
Addendum: The cart system you see me build can rightly only run 5 carts. Any more than that and the system ends up overloaded. Using a holding loop I was able to determine it's actually about 5.5 carts with a 100 tic spacer. Something in the system causes an eventual race condition for a single cart. I'm not sure what it is and I don't care enough to find it as long as I can get the # of carts and the holding loop to get it to behave its damned self. The stop-drop for the drop chute should be fixing the speed so I don't know how the hell it's happening though.
