sbuoncri Posted January 18, 2008 Share Posted January 18, 2008 Hello everyone, I'm new to the forum and very new to blacksmithing, I've been researching treatment of tool steels and I'm starting my preliminary design for a forge. I found one design by a steel treatment book from 1936 that describes a forge called a "Semi Muffle forge." The design is a full brick bottom with a rounded top. Here's what the drawing looks like in the book. I've been told that my burners would have to be be blower burners to get the needed heat distribution that I'm going for. My goal is to create very even heat distribution for treatment of tool steels for woodworking edge tools. does anyone have any advice or experience on making this style of forge? I found a site that sells burners called zoellerforge.com. Is the opening on the side of the burner used to connect a blower? Thanks!

matt87 Posted January 18, 2008 Share Posted January 18, 2008 Welcome, Scott! What do you want to do with the forge? Temper steel? Bring metal to forging temperature? If the former you're better off with a toaster oven (or even your kitchen oven), if the latter there are many simpler designs around that are tried and tested. Not to rain on your parade or anything, ingenuity and DIY (even for the sake of DIY) is to be encouraged, but if you have a forge which is known good and you work with it for a while, you'll get a feel for how to design a good forge.

sbuoncri Posted January 18, 2008 Author Share Posted January 18, 2008 I'd be using it to harden A-2 and O-1 tool steels in fairly small pieces. I plan on tempering in the oven. Each chisel is about 1/2"x1/2"x6". I would much rather build a forge design that is known to provide very even heating. Are there any specific plans your speaking of? A simple furnace with Reil style burner/burners would be a lot more convenient to make. Where could I find a design known to provide even heat? Thank you very much Quote Link to comment Share on other sites More sharing options...
Ice Czar Posted January 18, 2008 Share Posted January 18, 2008 muffles be they full or semi are a terminology often seen in Kiln design Kilns, Furnaces and Forges being xxxx near the same thing, In kilns however certain kinds of ceramics and glazes do better without direct flame exposure (the muffle being a wall that protects from the flame), designing the heat flow within a kiln and through a stack of greenware is a fine art, the most obvious differences between a kiln, furnace and forge is the volume involved, the ramping regimen and peak temperature. this may be usefulLayout of Topics Grouped by Area specificallyBurner BuildingBurner ChoicesControllers and Controlling Electric PowerRefractoriesFurnace BuildingBuilding a Sheet Metal Annealer of course there is alot more there and with the leads good search terms for other sites ;) Quote Link to comment Share on other sites More sharing options...
