Michael Cochran Posted January 4, 2016 Share Posted January 4, 2016 I have used both fires that were both round and rectangular and was curious what the real differences are. I have tried a few searches but I guess I'm using the wrong search terms since I haven't found anything discussing the shapes and the impact it has on the work being done.

turbo7 Posted January 4, 2016 Share Posted January 4, 2016 Mate I think the big difference is fuel economy. Quote Link to comment Share on other sites More sharing options...
Frosty Posted January 4, 2016 Share Posted January 4, 2016 I'm not normally a solid fuel forge guy but I've never noticed a significant difference in the shapes. Some project might need a long narrow or big round fire but that argues for a duck's nest unless you have a lot to make. Frosty The Lucky.

forgemaster Posted January 4, 2016 Share Posted January 4, 2016 Where I started my apprenticeship they had long fires as they did a lot of springs, the job in hand dictates the shape of the fire that you build. That is one of the advantages of a forge fire. Quote Link to comment Share on other sites More sharing options...
SmoothBore Posted January 4, 2016 Share Posted January 4, 2016 With a Coal fire, perhaps the shape and style of your Forge "Pot" ( Duck's Nest vs: Rivet type ) has the most impact on the efficiency of the fire. Both of those are, of course, "Bottom Blast" Forges. I don't have enough experience with "Side Blast" systems, to make intelligent comment on their characteristics, ... but would assume they would be more versatile, in regard to the shape of the fire. Since I make it a "point", to never be in a hurry, ... I tend to keep my Forge Fire small and "manageable". This is sometimes "counter-productive", ... but when you've eliminated any serious "Profit Motive" from your "Business Plan" ... it's not a problem. .

Glenn Posted January 4, 2016 Share Posted January 4, 2016 The metal does not care how it gets hot, just that it does get hot before you start hitting on it. The beauty of solid fuel is that you CAN adjust the shape of the fire for the project at hand. No one ever sid you could have only one forge.

Charles R. Stevens Posted January 4, 2016 Share Posted January 4, 2016 Try explaining that your significant other, lol Glenn. A round pot doesn't fit brick work as easy as square, even tho an 8" round pot will hold less fuel (and fire doesnt naturally grow in square shapes) than a square pot.

Michael Cochran Posted January 4, 2016 Author Share Posted January 4, 2016 I appreciate your input guys. I had to ask because I'm building a new forge and I wanted to make sure there wasn't any big differences I needed to know about. I had planned on a rectangular fire pot since that's what I'm used to but didn't want to build it until I asked. Quote Link to comment Share on other sites More sharing options...
rockstar.esq Posted January 5, 2016 Share Posted January 5, 2016 If it's funnel shaped in cross section, the fire will follow the pot's shape to some degree. Quote Link to comment Share on other sites More sharing options...
Michael Cochran Posted January 5, 2016 Author Share Posted January 5, 2016 The firepot is gonna be the kind with the trapezoid sides so the top is bigger than the bottom. I'm not sure just yet how big it's gonna be but I'm thinking about 8 inches long and 4 or so inches wide tapering down to maybe 7x3 inches.
