How do you pump stack magma with caverns in the way?
« on: December 19, 2014, 10:10:50 pm »

What I mean is is that in general I can't ever seem to get a clear open space of rock straight from lava sea to my fortress, there's usually a cavern (or two) sitting somewhere between, which would make my pump stack considerably more complicated. Any advice?

Well you can detour the pumpstack around the caverns, it doesn't have to be straight up and down. And then you just going to have to dwarf it up and deal with the added complications. Or you can dwarf it up again and break out the military to guard your builders while you construct the pumpstack through the various caverns, and deal with the complications from that. Really either way you decide to go about getting your magma pumpstack to the surface, it will take some work. There really is no major advice for it, as both operations are fairly simple. It's just going to take you some patience and dwarf-time to do.

Big question is what are you planning to do with the magma on the surface. Are you planning a magma cannon defense, or just wanting to power your forges. If it is just forges, there are ways with minecarts to do it much more cheaply and quickly, or my fave way of just building the forges at the magma sea level. If you want the magma cannon, or any other application that requires large amounts of magma, then you'll want the pumpstack.

Anyways, good luck and happy dwarfing.

The one time I pump stacked through a cavern I had the militia guard the area while my masons walled it off so nothing could get in and destroy the stack.
