Are you talking about a grill or a smoker? having a fire directly against sheetmetal will burn out in no time.
if it is just a smoker I use #16 inside and out on my verticals with 2" mineral wool insulation.
Nice. I was going to suggest trying to use .5 for the firebox as that's where most of the heat loss will occur.
Much easier to ask questions here first than having to grind off welds and change things.
hi. Metric is no problem for me. Always better to er on the side of bigger if in doubt. Especially with a small cooker.
A local sheet metal place should be able to cut and bend what you need.
Thanks guys. Takes a bit to get going, so I open the main doors until the fire is going well before closing them. Once it heats up this thing barely makes any smoke at all. Nearly invisible
looks good. Tubing is for the trailer chassis? The door will move a bit when you cut it fully open, they all do that. How are you going to cut the 5/16" plate?
Nice going. Looking forward to see more pics. Don't be afraid to roll the tank around when cutting out the door to make it easier using the 9" grinder. be sure to stay 90* to the tank when cutting.
So you are going to put the seam under the main cooking chamber so is less visible? Run a small angleor T section where the join is to stop it bowing down if you stand on it.
I can put you in touch with my CAD designer in Croatia. (charges $15 hr) Send him a drawing with dimensions and he can knock you up a DXF file that you can send to your local plasma cutter. (Ivan, you can find him on Skype: oly7007 ) Then all you need to do is bolt the damper on and weld...
I wouldn't bother with mineral wool, maybe only for your main door. Lots of rock, brick then firebrick. Make sure you have ample drainage. Maybe dig a canal above it in the hillside to run off excess water.
Hi Hugh, I cut the tank ends off and re use them for fogons. Much, much quicker and easier to use flat steel and merge them together. Make a new post on the forum and we will walk you through the steps, BEFORE you start cutting.
looks good. I usually paint the chassis and Diamond plate first before installing it. Then good tack welds from underneath while someone stands on top to weight it down. Then you only need to paint the area where you welded underneath.
Looks good. If you are using counter weights you can reduce the top cut to 20cm and still be fine. You made a good decision posting here and asking BEFORE cutting. Many folks start cutting up the tank then come here asking how to do it after making errors.
Here's my 2 cents.
Is your bottom grate going to be fixed and below the cut line for the door?
3" is barely sufficient between your bottom grate and the RF plate. From your drawing you show the bottom cutout at 15"...That is 5" below the center line on the tank. I would move it up to 3-4" below...
Yesterday was a good day for us...... not so much for the pigs :) Pork is great I have a good supplier. Some of it comes from Brazil, but I normally use Argentine pork
