Just a save of a very basic fort which has a minecart magma delivery system, encase anyone wants to check it outSteps for creation- FInd the magma- Find a 5x5 area you can dig to the surface- Dig the track shaft- Build the ramps- Dig the minecart return shoot (I just made loads of up/down stairs then removed them all and then collasped a 1x1 tile onto them all)- Power the rollers somehow- Roller one goes slowly through magma to allow cart to fill with delicious magma- Roller two (on the last tile of magma) accelerates the cart.For my powering I had the ingenious idea of using my minecart return shoot to deliver a large payload of water from a river down to the magma level.dfhack Fast dwarf was used while digging/building the minecart shoot, as I was just building this example to show someone.
