Here is the 5"x5" tubing for the opening. It's about as big as I could go, I figured if it was too big I could get a piece of soft firebrick to block off part of the opening.

 

Here is a picture of the back pass-through so that longer stock can be used. For now I just shoved a piece of ceramic insulation in it to keep it plugged.

 

Front and rear installed, and a hard firebrick for the base.

 

And one more of it running.

 

Very nice!

so glad i found this, this is exactly what i wanted to make.

That looks to become a dyn-o-mite forge! I trust you plan to coat your ceramic blanket with a rigidasizer? I use a refractory mortar from AP Green. (Not sure if its available anymore though but many other options) an 1/8" coat makes a very durable chamber with a little care. 1/4", 3/8" and its near "bullet proof" ;) A reflective coating of a ITC 100 like product serves to increase the efficiency of the insulation...

 

Hope this helps

Zengineer,

 

Did you use any coating on the wool blanket? The reason I ask is the fiber breakdown/safety thing has always kept me from wanting to dive in to using ceramic wool. Cancer runs in my family and my dad died of lung cancer and having been smoke free since 2007 (GO ME!!!) I have been playing it safe.
