okay and what if the resevoir is already filled? or mostly filled? My plan is to have a magma fall feed from teh top of the resevoir and drain back into the resevoir at the bottom.

If you decide to clear the area like you are making a pit or pool, you end up having a harder time with ramps than you do with channels as you go through hell basically trying to get that final ramp removed.

if you aren't too concerned about things getting out have fun with the ramps.

I have a question regarding magma

lets say i've got a resevoir that is shaped like a cup (in that its closed on all sides except for the top)

what would this screw pump setup cause?

would the magma just not pump, cause the magma to over flow on teh top?

also, will creatures with the building destroyer tag destroy grates opposed to walking over them? Assuming there is a clear path into my fort?

have you modded temperatures on anything?

like thermonuclear cats?

any changes to stuff like that wont take effect imediately but will cause any new instances of the changed entity to have the changed stats.

so if you modded thermonuclear cats and htey had a cat or cat leather, ti woudl cause an explosive fire killing the merchants.

I'm not to sure but I think I may have read somewhere regarding corpses in obsidian that it enforces a quick decay so you would end up with bones and metal (I dont think bones melt imediately) stuck in the obsidian which would become free when mined. At least thats what i think I heard, it would have to take more test/research for me to be sure (I'll see if I can try it on my next ambus/siege whenever that happens... its slowing down a bit)

I dont think you can retrieve stuff once it falls into the pipe unless it catches on one of the upper levels, the bottom of the pipe constantly spews lava upwards, and you can drain the pipe but it might be extremely !!risky!!.

as for capping the pipe. there are two methods of quickly capping the lava pipe. The Easy way and the super easy way.

The easy way is to build a drainage system that drains the magma into a giant resevoir lowering the level in the pipe which prevents any imps from leaving it. (imps swim in magma, if the level is too low they cant exit the pipe.)

The really easy way is to cap the pipe with water. Basically go a floor above, make a floor/bridge structure, rig to collapse/retract, fill the structure with water and let her rip. This is a similar process when it comes to making an obsidian factory. (note obsidian factories use bridges for continued operations)

As for workshops.

in each of the workshops designs there are dark green X's these represent impassible tiles which, if placed over a hole in the floor over magma, will seal off the hole. You only need one tile accessable to magma, so with smelters you'll want your northern tile accessable and with forges you'll want either your east or west tiles open.

and for future fortresses.

you dont have to build right ontop of the pipe for magma access. with planning you can carve out a magma resevoir and breach the pipe for magma access. when doing this you can craft/designate a fortification to be placed, and with taht you can prevent the imps from coming through (supposedly) I'd still practice using the inaccessable spaces on the workshops to your benifit. Better safe than !!sorry!!

From my experience with screwpumps, you cannot power them from below unless there is a mechanical connection higher up the stack (assuming you are making a stack of screwpumps) otherwise the pump is hanging, and will deconstruct.

to power the pump from above you have to channel out teh floor before putting in the gear to supply power to the pump (you may be able to channel out the floor with the gear on it, but I've never tried it.)
