new and old forge

[donnymac250]

my new one is the black one

They both look pretty good. After you get the wool in the new one it looks to me like you might want to get a little more angle on the burner. What burner will you have on the new forge? Looks like you'll need a fairly large burner or a forge that size ...

new one is 10" dia pipe .1/2" wall thickness . 14" deep . pipe to hold burner is at a 10 deg angle forward and 10 deg upward in the center of the forge . im now wondering after talking to you sunday night if i should put 3" of insulation in it instead of 2" to take up more interior space . the burner is the same one off you tube that david hammer made .

Don,

I have to say I am a big fan of the old one, but I think it needs a little more duct tape. It looks way more fun to use! (just kidding LOL)

Awesome job on the new one. Hope it works super for you!

old one works great , but i wanted one for longer and larger knifes . thats not duct tape its metal tape .

!/2" wall thickness? Ouch! A third layer of wool will make the interior smaller and that would probably be a good thing but that much wool plus that massive amount of steel in the casing will create a substantial heat sink. It should still work, of course, but it means the forge will probably heat up much more slowly than necessary. A lot will depend on just how much heat that burner produces but no matter what more mass always means slower temperature rise.

On the other side of the argument, more mass also means slower cooling so that forge should be especially well suited to annealing ......

ya for sure . the only thing i will be using this for is anealing and getting my steel temp back up before i quench it . i have no plans of melting or welding .
