I will be building a gas fire pit for my deck. I figure I have two possible was to go.
The first is to get a new section of cement sewer pipe about 36 inches wide and cut a 18 inch piece of it off. Lay that on the deck and mortar rock veneer to it and create a flagstone ledge on top. Pros is it would be round, and look really nice. Cons is getting one and moving such a heavy thing somewhere to cut it.
The 2nd way is to build a octagon fire pit out of metal studs and cement board then veneer it with rock and create a flagstone ledge on top. Pros - much easier to do. Cons - won't be as pretty as a round one.
Question 1 - I don't think the standard non-load bearing metal studs made from 25 guage will be strong enough. Not sure if they make stronger ones or where to get them?
Question 2 - anybody else got any ideas on who to build one other then the ways I came up with? Gotta be cheap.
