I also picked up a 2", sch 40 PVC conduit, 90 degree. I had to heat and form it to get the radius I needed. But the idea was/is to form a channel in the castable that will "guide" the burner flame around the inside. After getting the dent I needed, I sawed the PVC with a taper around the curve that terminates about mid way on the opposite side of the forge that the burner enters.
I also used the 1/4" plywood to fill the front and back "doors", trying to ensure that castable would cover most of the steel portions of the doors.....again....used the duct tape to keep things in place.
