Dave (dwfisk) did a
really nice job on building Keith's.
Most of us do not have the $$/or want to spend to have a shop fab one up. I completed mine as cheap as I could, and have it function for my requirements.
There are alot of ways folks could put one together no welding required. Using locally sourced cheap stuff. Like CI pipe from HD for example. You could make a 4" high stand using 3/8's "T's", elbows and a few 6-12" pieces of pipe. That would sit on top of your drum, it would hold the grate and lid. It wouldn't be locked in, just resting. Though you could make it so things are locked in/on using 4 way crosses with some careful measuring. If anyone wanted just to try this method of cooking out. It would be kind of like bed table. If that makes it easier to visualize.
You could build a full 5 ft high stand that sit just outside the barrel width using CI pipe. Using a combination of 3/8's pipe for the forward/rearward legs for stabilization, some elbows, "T's", reducer bushing to go from 1/2" pipe that is just larger than 3/4" O.D. to the 3/8's where required. You would want the 1/2 pipe for the upright pole, Not 3/8's! Drill out the threads of a 1/2 union so 1/2 pipe slides thru, drill/tap to 1/4-20, that union to use as the lock collar. Drill out the threads on a 1/2 cross in the vertical position only. That will become your swing grate but allow you to thread in a piece of pipe on the back side of where the grate will be to use as your swing handle, I'd use reducer bushings and go to 3/8's pipe for the handle and grate. The grate/lid holder can be built using 3/8's pipe. In a configuration kind of like an old TV ant. If you can screw pipe together you can built this. The only pipe that would have to be tight would be for the swing grate section.
Or if you have a friend who can weld you can put together one using angle iron, CI pipe for the swing grate and lock collar. Like shown on pg 9.
Lots of way to put this together.
You would not do it this way if you were going fab and to sell the units. This is just for the folks that want to try this method and have something that works. That they can put together themselves.
The other thing, if you build it out of the pipe, you could remove the 5 or 6ft tall upright piece of pipe and use a 3 ft piece for using over a camp fire. The whole thing would/should come apart easily since nothing was tightened much. Makes for easy packing.
Just a couple thoughts.
Here are my 2 versions. They were put together to see if I would like this method of cooking. If I was to make new ones, I'd do more detail work to make them look nicer, not just thrown together off the top of my head..... prototype
my grate for under the swing grate option for using pans etc.
I used the clamp ring that came with my drum, as my lid fits that and my drum.
For my requirements, I found I don't really need a swing grate. So I threw this together. I did not think I would like it, but I really do prefer it for my needs. Ugly but works. It is stuff I have laying around, nothing fancy or nice. Just works.
And my option of height addition for getting more space between the cooking grate and top of the dome lid, when required.
