Hi everyone! This is my first post here!
I'm sorry to use an old topic, but it's better to recycle than create a new one on the same topic, right?
So I took a one-year blacksmithing course at Herefordshire's College of Technology in, you've guessed it, Herefordshire in the UK. It was excellent! Then I came back to Portugal, and I've been in university ever since, so I've had no time for forging... These holidays, however, I finally got everything together and managed to hit some hot metal! It was great! I did ended up burning my piece (it was going to be a fire rake), turning it into... well, two pieces. Heheh.
I think I've found the reason, but I need your help making sure that was it, and how to solve it. I was used to coke, which was heavy stuff. The fire nearly went out after about 10 or 15 minutes without blowing, and it created a fair bit of clinker (a large, closed fist after about an hour and a half).
So far, I've only managed to find charcoal - pine, I think, so that's what I'm using, here in Portugal. I've attached a picture of my forge. The actual firepot is really small, only being around 4" wide and 2, 3 or so deep (I'm European, so I hope I've gotten the measurements right).
First of all, there's a HUGE, horrible amount of flying burning fleas. Me and my sweetheart (who I convinced to join me, yay!) looked like we had freckles all over for awhile. It's hard to move the charcoal around and keep a blast going, because we get all burnt.
Second, that stuff is LIGHT! After a half hour or so, it seems like all we have in the fire is pinky-fingernail sized pieces. We do add some more, but they're still there, and fly off if we increase the air-blast. I also think that, related to this lightness, it is common for the firepot to become an open dome full of oxygen, because of the constant air flow. Unfortunately, since the pot is so shallow, that ends up being where I put my piece. Oxidation paradise. I had been drawing out the 16x16mm square bar I had (a bit more than half-inch), so it was pretty thin, and I think that as soon as it hit yellow (which is darn hard with that charcoal flying off and creating that dome), it burnt away.
So, short of finding a new source of (char)coal, is there anything I can do? I do have access to clay (the grey type), but I'm not sure I want to put too much of it on there because of the weight. It seems like the ideal thing would be to increase the depth of the firepot though. Not sure that would avoid the empty dome... no idea about the fleas.
Sorry about the long post! I hope I manage to keep coming here every once in awhile. It'll be kind of hard!
