Frosty I'd like to apologize for my snarky reply to your first post in this thread. I was feeling kind of attacked for having asked a legitimate question and reacted before fully assessing the situation. After reading/skimming a few threads I get where you were coming from. There IS a ton of info on this board, and you seem to heavily contribute to most of them, with a knowledge base that is self-evident and freely shared. That being the case, I can see where you would feel it was a never-ending job answering these posts. And so, Mea Culpa. I apologize. Thank you for bothering to reply at all. To try to explain myself, I will just say that I am not someone who frequently visits forums. I really didn't (don't") know how they work. I was (am) extending myself into a new area of inquiry, and google presented me with this forum after a search for the info I was looking for. I just wanted some particular information, and not realizing the "personality" of this community, I just started a new thread to try to get the specific info I needed. I didn't really even look through available archives. In my defense, I still see having to spend tens of hours reading through the threads to get the few hours reading of information I need for my small project, since I want to build a Multi-port burner and almost EVERYTHING I've been through so far is about traditional burners (BTW, Impressive thread on your NARB {or should we call it NAMPB for Multi-Port}), but I get where you're coming from. The info is already there for someone willing to put in the effort. I'll proceed in that direction. Again, Sorry Frosty. It occurs to me that "Frosty" is just another way to say, "Cool"

Thank you, Frosty. I 'm reading through the thread now. lot's of good info.

Frosty Frosty, thanks for the warm welcome followed by the insult fest. A simple link to an answering thread would have done. Since this is my first build and I specifically joined the group to learn, not just how to be successful with it, but what things I need to consider, I can't express fully just how encouraging I found your post. I especially appreciated the veiled slur upon my intelligence and expression of your superiority. I hardly believe someone with such a cordial way about them could be known as "Frosty". Can we all shout "Misnomer"?

That makes a lot of sense. Realistically, a machete is probably the biggest thing I'll make. but I want it to fit odd shapes as I would like to beat out more than just blades. I don't even know what yet, but I'm one of these "interested in everything that comes to my attention" guys, so I don't want to limit myself too much. The open ends with firebrick as per project sounds like a perfect solution. And I can always build hinged doors for the ends later if I save the cut off pieces. This is why I wanted to start a thread before I started work. So with a 9" or 10" interior and a 12" length, could I reach forge welding temps with a 2" X 6" burner? Or would 3" X 6" be better? What size input piping for the (forced) air supply? 1/2" good for the propane, or 3/4"? what would be a good size grid for the holes? I really appreciate the input

Buzzkill, Thanks for the input.. I was just thinking that big because the company I work for was throwing out a tank that size. I can always cut the length down, but It will have the 9" or 10" finished interior dimension. What would you recommend for length? Front and back opening size? I can plan any size burner, as I haven't started gathering material for that yet. From your post it sounds like a 12"-14" length would be more than adequate. When you say naturally aspirated ribbon burner, are you describing one with no blower?. I plan on a forced air burner, so how do I figure what size input piping for a given size burner? I would appreciate any input you could give on any of the above questions.

I've gotten a tank, and the blanket and IR coating is on the way for my very first home built forge. Now I'm looking for burner parts for a ribbon burner. Is the castable refractory you can get at Home Depot or Lowes of high enough quality, or do I need to get tougher stuff? Also, would two 9" X 3" burners be sufficient for a 14" X 26" Forge housing with 2" of durablanket (for a 12" interior)? Any other important considerations as I'm planning the build?
