    You don't need a long forge to H/T swords. Japanese swordsmiths have been doing it for years with a small pile of coal on the floor.
    Start small with knives before you try for swords. Learn to walk before you run.

    Alright I finally got started on my first little forge and got most of it done, it just needs the kaowool to be cleaned up a little more, a torch and the coating stuff which should be in the mail somewhere. Some of the weldings looking pretty ugly because I've only just learnt to use the arc welder. I'm hoping to get stuck into the bigger cylinder by next school holidays at the latest.

    Looks like you used 25mm isowool on that forge. if you have it's not enough, you need at least 50mm. You won't need to coat it in refractory cement just a coat of ridgidiser is enough.

    I used 25mm but I doubled it up. I may have made the opening a bit small if you think its too thin.

    I was testing out my burners for the forge and to my disappointment it was creating hardly any flames and nowhere near enough heat. When I lit it up the flames would burn inside the burner tube and heated up the burner and there was hardly any flames coming out of the forge when it was on full bore. I'm guessing that it was the regulator as it only lets the gas out at 75kpa or about 10 psi. My contact tips are .8 mm.
    Am I correct that the problem is most likely the regulator?

    Here's a video of it running:
