Hello - I am getting ready to build another rocket stove. My design is something similar to what the company with a brand name called " Liberator " is.
I have made one before and am going to build another hopefully with some improvements. The " Liberator" company seemed to use 5" square stock for the feed tube, burner and rise and I did as well as this was a material fairly easy for me to get. I am certainly a novice at the whole thing having only built 1 stove. I have seen several reviews of their stove and it seems as though they are lining the inside of the riser with a fire brick bolted or screwed to the side of the 5" tube- here is the link in which I saw this----

Several questions- the fire brick seems rather long ( looks like it goes all the way down) is this really firebrick ? can you drill firebrick? how do you drill through it? and where do you get such a long product?(most I see are 9" long-these seem maybe 30" long)
