FInally managed to tune the gas forge so that it doesn't tend to perform Moon flights anymore. So, I'm able to forge again! Not as good as the usual coal forge, but until I can solve out the chimney, I'll have to get used to this. It heats quickly and buying gas containers is easier that buying forge coal, but I hate the sound it makes, I'll likely have to wear either earmuffs, or mp3 speakers all the time. But I'm able to revive an important part of my income with it, so I'm quite happy. Already prepared a first batch of my long-paused project of tactical hatchets, based on an 9th century slavic shape. Those will go to a factory for furnace heat treatment (faster and cheaper than doing that myself), but I've also made and heat treated four knife blades in the new forge. At first I wasn't able to temper them correctly, as the heated too fast, but that's ok now. I need to try forge-welding on the new forge yet, though the manufacturer said it's possible. It will certainly be clean enough, but will see about temperature.
So guess I should start stocking some extra gas cans now. Though if the real SHTF came, I doubt anyone would complain if I just used my old coal forge outdoors. I should also finally have some masons coming here for several tasks, so I'll see if they would fix the chimney in the antique smithy, so I could work there.
