Oh, and did I say it ? Thanks again :)
- i see you pound the uprights about a foot in the ground.
For an all round oven rack - you could use the same priciple of screwing the piping together but go for an A-frame style on each end.
No pounding of the uprights in the ground and might be a bit more stable all round.
I'm just thinking of if it rains and the ground soaks and your pots/ovens are full - the wind starts blowing - pots / ovens start swinging - you may find your next meal on the ground being eaten by the critters.
Plus with an A-frame style you can go with lighter weight piping for the uprights.
another idea just looking at it - to prevent the pots chain from slipping you could use say 10" pieces of piping - with a coupler 1.5"nipple - then coupler then 10" piece and the same again to make up the horizontal support (top pipe) the nipple in the middel of the couplers would prevent the chain from slipping side to side or down the pipe - say if you tip the pot/oven to one side - like scooping out that last deliscious drop of campifire stew...?
just some thoughts... but nice job and one last question...
So... when is dinner being served?
Come on down... we'll drink breakfast together!

I also like the suggestion to add tee-connectors to the bottom of each leg. To avoid having to stake the connectors to the ground, though, you could run another length of pipe through each of the bottom tee-connectors to make the whole thing stable and free-standing.
Step 3 - Perhaps putting a piece of wood on the pipe before whacking it with the back of an axe might be a tad safer for the metal. Black pipe tends to crack or shatter when struck repeatedly. If this critical point breaks we'd starve. ;)
Another thought - if you put Ts at the bottom of the vertical pipes you might not need to pound this in the ground. You could anchor the inverted Ts with a few stakes made out of rebar bent in a U shape.
Cheers!
