I rented a wet saw -the Mason Mite II- to cut my firebricks in half. The results were spectacular as I halved 100 in about 90 minutes, including learning to use the saw and refilling the water and discarding used water. After reading how cumbersome and dusty the chop saw was, the $70 seems like an excellent investment. The cuts are amazingly clean, and I cut several odd sizes for possible use as keystones. There was no dust and clean up was a snap. That being said I have a couple questions. First, is it acceptable to set the oven floor in place with refractory mortar? I was told by staff at my materials supplier that fireclay and refractory mortar are the same thing. Second, how long does the floor have to set before construction of the dome can begin? Lastly, how many rings of the dome can one build consecutively without compromising strength and risking collapse? In other words does each ring need to cure or set before moving on to the next? Thanks in advance for your wisdom.
