Hi all. I was going to finally get around to putting together my forge this afternoon and I have a couple of quick questions. I've looked through all of the instructions I could find but somethings are'nt really specifically covered and I want to be sure.

  • I was planning on using 2 mapp ez burners to get extra heat, is there any reason why this would'nt work?
  • Can I just put a firebrick on the floor of it to make the floor more easily replaced?
  • How can I stick the wool to the inside of the can?
  • Am I correct in that the ITC 100 is jsut painted right onto the wool?

Thanks in advance for the help guys.
 
You can use refractory cement to stick the wool to the inside of the can and yes, you just paint the ITC on. You can use firebrick if you want, but you may wish to put it on top of the wool, instead of in place of the wool. I don't know how much room you'll have in that case. The simple design and inexpensive nature of the coffee can forge allows you to just replace the whole thing if it wears out.

I'm not sure I'm following you with the MAPP burners, you shouldn't need two MAPP burners in a forge that small. I've had some experience with the MAPP torches in a 1-brick forge and will say that it gets hot very quickly but also heats the tip of the torch very quickly. I have blown out one tip using MAPP gas this way. If you want to use two, I'd make sure there's enough space that they don't heat up the other tip more than necessary.
 
Sorry, I left out a part

I'm not actually using a coffee can. I'm rolling an 18" section of sheet metal to get a tube longer than a coffee can but roughly the same diameter. I was thinking of using the 2 burners to make up for the extra length.

With the brick, that's what I meant, on top of the wool.
 
You might end up with hot spots and cool spots with those burners. If you're going to go outside the coffee can "box", you might want to look into venturi burners. Someone with more "advanced" forge building experience should be able to clear that part up better than me.
 
hmmm, I was just wanting to get a bit more capacity for longer projects. Although, now that I thik about it for a second i would only be working with a small section of even a small peice at a time. Perhaps I'll just do the coffee can.

Do you think it would mess anything up to squash it down a bit to make it slightly elliptical to get a bit more width?
