I finally got around to working on it this week.
Here's the asador
Mounted a 200 mm stack on the side and decided to put it where all the tank outlets were to get rid of them. i welded in T bar upside down to mount the firebricks on, so if it gets wet it can drain easy and not rust. Tomorrow I have to build a boat trailer for the father in law :( so will test it out.
I purchased a bunch of these 125 gallon tanks, so will start knocking out some of these smokers. I am trying to mount the fire box as high as posible (tanks are 762mm, 30" diameter).
So trying to get it low enough for a working height. I am going to do something different with the stack I will sheetmetal behind the grate guides from the top down to the lowest guide, so the smoke has to go down then out the stack. My thieory is that the smoke will get heated against the edge of the firebox causing it to draw more. For the reverse flow plate to save on steel plate (shit's expensive down here) I cut a piece out of a 110cm diameter tank I have. ( I am going to use the tanks ends for al asadors, so am left with the cylinder, so will chop it up for reverse flow plates. I cut the piece out of the tank then put it on my steel work table that is 3" thick and treated it to some love with a 40lb sledge. Took some of the curve out of it. I am building another 500 gallon soon so will probably take the cut out to the sheetmetal shop that has a monster press so they can flatten it a bit.
I am waiting on the plasma cutter to cut out the firebox doors.
Here's the tank cut to get the reverse flow plate for the 30 " smokers I am building. Thats a 500 gallon in the background to give you an idea how big it is.
Here's looking at the brasero from upside down. The grate then above it the breaker bar which has a handle on the outside. so you rattle it back/forth to knock all the wood/coals down for the parrilla.
Here's the brasero (burns wood to make coals for the parrilla) throw wood in the top and shovel coals out the bottom. Has a 1 1/4" bar running through it to shake the coals down.
I will post some pics of the cook tomorrow with R2D2.
