These are bad solutions. You don't have to bother with a pump or with letting your miner catch on fire in the first place. Either dig stairs up to the top of the caldera and channel the final square from above magma level, and let it flow down the stairs to where you want it, or build a magma-safe bridge right up to the side of the volcano at any level with a channel under it and a separate hallway leading there one z-level below. Block access to the top hallway and then designate the wall to be mined. The miner will go under the bridge in the bottom hallway and mine the wall from the ramp through the bridge from below, and the magma will just flow over the bridge and never touch him.
No, THIS is a bad solution, as the magma at the top will replenish slowly, and falling magma now creates magma mist. Door+diagonal fortifications FTW.
Strongly disagree. Magma mist is irrelevant, your dwarves won't be standing anywhere they can be misted. Magma replenishing is a good thing for most applications, and doesn't hurt others. Most importantly, it allows for fast magma flow, which is very helpful for anything requiring large volumes of magma. Diagonal fortifications are faster to set up and work fine if you're just setting up magma forges and such, but for high-volume applications the bridge method is the way to go.
Explain how, in the post I quoted, dwarfs will not be standing next to magma mist. They will be standing next to falling magma, and they will get burned. Have you even tried this in the new release?
Herp derp, of course replenishing is good. You drastically misunderstood me. If you tap at the top, you will be taking from the top and your overall flow rate will be limited by the replenishment rate. If you take from below the top the magma next to your inlet will maintain a level of 7/7 until all levels above have been depleted. When you tap from the top, magma will deplete to below 7/7 and you will not have a full magma reservoir until the magma replenishes.
I repeat, please don't listen to Sabreur on this unless you really want lots of !!FUN!!, and a long wait until your magma workshops are at 4/7. If you like burning dwarves and waiting a year for your magma workshops to start up, then by all means follow Sabreur's advice.
I've never tried the under-the-bridge method but I don't see how a Dwarf under the bridge can be exposed to magma mist. Also, the bridge can be placed at any level so you are not limited to draining just the top layer of the volcano.
I have tapped magma pipes at the top level, to a same-level reservoir, and not had a very long wait until the workshops can be used. Then again, I never need a very big forge room. One kiln, one glass furnace, and one or two each of smelters and forges usually fills my needs. If I were going to let it flow down a stairwell, I would first build a floor over the top of the stairwell to prevent any mist from rising. Then the situation should be the same as I have been doing with same-level reservoirs.
I can say from experience that the diagonal fortification
without a door is fatal now. I'd be more inclined to give the bridge method a try than to add a door to the diagonal fortification method, simply because I like the idea of getting a wider channel if I'm going to build something anyway.
