Recommendation? Making a heat treat forge

[irawesome03]

I looked up some tutorials about making a heat treat forge, but they all seem too small. I want to start small in making knives, but eventually, I want to make something over 12 inches(maybe around 16). Should I just buy some firebrick and make a 20-inch long forge without any guides? If so how many torches would I need, and what brands do you recommend? Do I use refractory cement to put them together? Any help is appreciated, and thank you in advance!!
