Kaowool Question

I would like to know if I need to adhere the kaowool to the inside of the forge. I am in the process of making a gas forge out of a new propane tank. I do have some furnace cement that is rated for 3000 degrees. If I do have to adhere it what options do I have besides the furnace cement.

Thanks
Mark
 
No, adhesive isn't necessary. Cut the kawool (with metal cutting shears/tin snips as it will wreck any scissors) to the length (front to back of the body you intend to use), then measure the inside diameter of the forge body (in this case the inside diameter of the tank), then cut the kawool just a tad bigger (usually 1/2" to 1"). Roll the kawood, place it inside the body and unroll it to fill the inside diameter, with the ends butted against each other (I'm assume you are building the forge in a horizontal orientation) at the bottom. The use a firebrick "split" to cover the joint/act as the floor. (a fire brick split is a firebrick that is 1/2 the thickness of a standard firebrick.)
