Using pumps, as long as the back tile (the one that can be pathed through) is not submerged in magma, they won't melt or burn, even wooden ones.

Wrong, see this movie:

You probably shouldn't pass on advice about the game that you obviously didn't test for yourself.

I think he means that this setup should work (I didn't really got to see it in your video)

Code: [Select]

. = channel
%% = pump
///////////////
. . . %% . . .
//////////////

This way, the magma never really touches the pump, since it drops down in the channel.

Please tell me if I'm saying something terribly wrong, just a noob trying to be helpfull.

Only one way to find out 

[forsaken1111]

I thought magma mist was harmless now. Has this been tested?

[Musluk]

Out of dwarves to test in my current fort. Gotta breach that aquifer first!

I'm surprised it took 30 hours for someone to point out that magmafalls (which the OP was quite clearly trying to make; why would he be wanting bauxite if not to pump magma up to a higher level to be dropped back down again?) don't create magma mist. And off the top of my head, magma mist is indeed harmless...but my testing was quite a while ago and the guinea-pigs were all killed by a magmafall "accident" anyway

[Hamster Man]

It doesn't?!

... damn.

[pushy]

It doesn't?!

... damn.

Nope. That one I can guarantee - if you go to the trouble of making a waterfall with magma, you're wasting your time (unless it's for fortress defence, in which case it may be rather interesting ) because it won't generate mist of any kind and dwarves will not gain a happy thought from it.

I thought it was an unlikely idea, but amazingly, it worked. I don't know why, because the magma doesn't only drop down in the channel.
Water on the upper level, sitting on top of 7/7 water on the lower level, would teleport via pressure to the first available place on a lower z-level. But magma doesn't have its own pressure, so the lower level fills only slightly faster than the upper level, and the tile behind the pump is constantly full of 7/7 magma.

I made a movie, but it is larger than DFMA's 1MB limit, because I watched the pump run for quite a while, expecting it to catch fire.
My original theory was that, since no other buildings are affected by magma in adjacent tiles, pumps probably weren't either, and their catching fire was probably a special case based on the fact that they were pumping magma, and not on the location of the magma. It's apparently wrong, because the pump ran for a while via manual dwarf pumping, and then I built a windmill and hooked it up to see if pumps only caught fire when running on power, and it still kept running.
I find this particularly baffling because the tile behind the pump had 7/7 magma on it the whole time anyway due to the no-pressure effect mentioned above.
Another experiment to follow.

Heh, fair enough. I'd seen some quite vehement arguments to the contrary, and accepted them as such. :p

[Hyndis]

meh, I just edited steel so that you can make mechanisms out of it at the forge.

You can also make clothes out of the steel too, if you've modded it as I think you have.

Only downside is that the task doesn't show up on the job manager, so you have to manually assign it at the individual forges.

I didn't have "pretty-mist happy thoughts" in mind. I was thinking more of "melting-goblins happy thoughts"

*sigh* I guess trapping goblins between magmafalls is just as good. If not as cool.

I've heard that pumps pressurize magma though-

So if I had a pump dumping magma into a channel that eventually opened up to a higher level could I flood that room? I've wanted to build a goblin trap like that for awhile since magma moving like that would be "unexpected."

I think that the wood slowly takes heat damage. Magma heats up adjacent tiles.  The pump won't outright catch on fire, but it will start to selfdestruct.  It takes a long time though. Only what I've heard. Not far enough to test.
