Hi, I'm still debating on how will I build my forge! I've read a lot on it and thought I would make the kaowool + satanite + ir coating. But now I've seen Wayne Coe forge on his Web site which is made from castable refractory over kaowool! I've not seen a lot of this kind of forge on the Web but for me it looks like the way to go. I want to do general small blacksmith projects, knife making and in the future make some long blades. I was thinking of 1 or 2 inch of kaowool with 1 inch of kast-o-lite +ir coating in the future! I would just put a solid form in middle of my casing, pour the end with castable, then put my kaowool, pour some castable around the form and over the kaowool, and finally cover the kaowool at the front. So the wool is completely encapsulated by the castable This way the concrete would support itself on each end when cured and put horizontaly and it would not crush the wool. I just don't want to alway make repair on the coating so I thought it would be more durable this way and will endure forge welding in the future! What are your thoughts on this configuration ? Thanks!
