We built this a few months ago started with a big 5ft 3/8 in oil pipe we got for free, around 600$ later plus paying my wifes uncle for his work it was done
There's a 5ft cooking chamber 3/8 thick with a 2ft firebox 1/4 thick ends capped 1/4 inch flat a little trim and square tubing for legs(with the weight we didn't trust angle iron)
It's a beast of a grill especially when you try to move it lol. We did put cast wheels on the back but it's still a 2 person job to lift and pull,
We were worried about heat since the box is so long but very little charcoal in the firebox keeps my heat at a constant 225-250, I'm sure i'm getting a little heat loss at the edges. I'm looking to get gaskets but dont know what to get, Any suggestions would be appreciated.
