Okay, after devoting a full season to mining and construction and losing half a dozen trained dwarves to FIRE IMPS EVERYWHERE OH GOD, I've finally got a huge awesome magma forge/smelter system built directly over my volcano. Only now my bloody ingrate blacksmiths refuse to go anywhere near it. I know it works, I've gotten an axe and about ten iron bars out of it (over the course of an
entire year), and the area's getting accessed constantly by Imp Patrol and miners stacking my huge, useless ore stockpile next door so it's not like it's inaccessible. Even with all other jobs turned off they'd sooner sit around with no job or wait for something to pop out of the farm than touch the factory. What the hell is going on? What can I do to make them work? Can I, at the very least, appoint a Hammerdwarf to beat them senseless day and night until they stop slacking off so I feel better about the whole situation? I don't want to have to go back to charcoal-based production again, I don't have any coal mines handy and only have enough wood to supply my carpenters, and I'm sitting on an awesome high-efficiency metal factory so sticking with stone is out of the question.
Also, FYI I've noticed that units stationed over volcanos for a long period of time spontanteously combust. If you want to guard the place, give your troops a patrol point that's a few squares out of the heat so that they'll take a break once in a while and not explode.
