What is the most effective way to dig 1x1 hole across 100 z-levels?

I needed it as a sealed water drain, or to deliver sand to magma kiln, and the amount of service tunnels and other work needed to make 1x1 hole is insane.

I wasn't able to make dorf channel the hole all the way, even if locked, he aborts the task after 3-7 z-levels and just chills in the hole with "No job".

Dig your chute using up/down stairs instead, then channel just the top tile. Liquids, items, and minecarts that are already falling when they reach the stairs will fall all the way down to the bottom of the stairwell.

Is there a way to reuse stones in a stone fall trap?  Every time one is triggered the mechanic hauls a stone to load the trap, but there is a perfectly good stone already right there.

the mechanics just take the stone closest to them when they reload it, if you want to use specific stones or re-use them you have to forbid all of the stone and un-forbid the stone you want to use then they will use that stone only.

The wiki states: Keep in mind that your population must be at least 80 to get a king and 100 to obtain the current game features.

Which game features require 100 dwarves? Does this 100 include children and visitor citizens or does it need to be adult dwarves?

I'm tired of having so many dwarves that I don't know who they are, trying to find the best population cap for my next play.

(EDIT) Well I guess that part of the wiki is wrong, it takes 140 to get a metropolis and have a monarch arrive. What does 100 get you or is the above quote from the wiki entirely wrong?

Two questions about war animals and pets:

Do assigned war animals provide the same happy thought (scaled with value) as a pet that's been adopted?

Do war animals, and pets in general, have less taxing pathfinding that say a pastured animal?

[Romeofalling]

Not an expert, but dwarves get upset if their assigned war animals die. AFAIK, pastured animals in a locked room have the lowest pathfinding calculations, but I'm even less of an expert on that stuff.

Do war animals, and pets in general, have less taxing pathfinding that say a pastured animal?

Probably not. A pastured animal stays in the pasture and moves occasionally (more often for grazers that are looking for more food). War animals and pets are following a dwarf and are either constantly path-finding over a short distance, or are following the path laid out by the dwarf (with short-distance pathfinding required if the path is blocked). Which ever method it uses, it is likely to use more FPS due to the constant movement of the dwarf that is being followed. War animals do not need to be assigned and you can put 100 war dogs in a one cage, linked to a lever.

Quick question about blocking off water channels:

Normally, you can block enemies coming through water by using fortifications. But I've read here on the forum that enemies can sometimes swim through them if they are 7/7 filled.
It is my understanding that enemies can't swim through bars or grates. But these have the problem that they can be destroyed by building destroyers.

So far I've used multi-level siphon designs to prevent building destroyers destroying the grates.

But, what if you use a fortification and grate in succesion? the enemy can't swim through the fortification because there is no place to stand behind the fortification, and the enemy can't destroy the grate because there is no place to stand in front of the grate while destroying it.

Would this allow for a same-level fool-proof barrier?

(Possible addition for ranged building destroyers, having 2 fortifications, going diagonal and back to prevent line of sight to the grate)

Two issues:
1. They can sit inside the fortification.
2. Building destroyers attack from 2 tiles away.

MY TIME HAS COME AGAIN. The third one about Grates is most pertinent to your question, and also involves a famous celebrity.

Spoiler: On creating a safely sealed, accessible waterway (click to show/hide)

The main thing is to create a renewable (or at least vast in volume) course of water for sick or injured dwarves, and for non-dwarf residents. However, you don't want dangerous baddies to sneak in to the system from outside, and you don't want to flood your fort.

Below is a 100% SUPER GREAT SERIES of diagrams showing how to do all this safely. So long as the water source is large enough, you can pump water to anywhere in your fort. Use grates as shown to prevent anything from entering your fort through the water system. You can even link the grates to levers if you want to access those sections of pipe later (for cleaning, perhaps). This is also the purpose of the drains in each section of pipe.

Grates are invulnerable from below, BUT it's important to note that there must be no accessible path to the rear (right hand) grate (see third diagram). This is the reason for the front (left most) grate.

Spoiler: On piercing water sources (click to show/hide)

You can almost always use this method to safely pierce a source of water from the side or above. Be sure to only pierce it after your safe pipeline is completed.

You can also pierce an aquifer from below to achieve this effect. It is more dangerous in terms of initial drowning, but hey, no baddies will ever come through your pipe if it's sourced from solid rock.

Spoiler: A GREAT diagram for GRATES ah-hah-hah (click to show/hide)

It is also easy to add wells to your underground pipe system. Just make sure that the water flows diagonally from the pressurized pipe to the well area. Your dwarves should have no problem escaping the rapidly filling well area, and the water will not rise above the well level.

Spoiler: Visual on diagonal water movement (click to show/hide)

It's worth noting that there has been concern that when adding a new well onto the system that dwarves will get caught and drowned as the well fills.

In my experience constructing it exactly as shown and making that one-space connection to the main pipe allows the water to flow diagonally in two directions, which fills slow enough that a dwarf will always escape.

God but I love posting these anytime anyone mentions waterways.

Thanks for the images Dunamisdeos. But like I said in my original post, I'm already using these kind of multi z-level siphons, so I was hoping for a simpler same z-level solution (although, is siphon the correct term for it? those swan necks below sinks, English isn't my native language).

The diagonal wasn't meant for water pressure, but for breaking line of sight to the wall grate, like this:

Code: [Select]

                WWWWWWW
water source >> 77FWG77 >> to fort
                WWWFWWW
                WWWWWWW

F = fortification
G = wall grate or vertical bars

But as Bumber pointed out, that won't work when FB's can sit in fortifications...

Use grates in the same z, and have the z-1 siphon (DF's gravity water pressure filter).

z+0

##########d++++#  d = down stairs
##########L#+o++  + = floor

The swan neck below the sink is called a "trap" or an "S-bend" in America, and might have other names in other English-speaking countries.

I seriously just get excited any time someone mentions water pressure, i'll try and reign it back.

Anyhoo I don't know of any successful 1-z methods. Not outside of a raising bridge that you lower/raise when you want water.
