I needed a deep outdoor cooking pot that would contain splashes of hot oil and was easy to clean. I cut the top off of an old keg shell I had lying around and attached it to a LP burner ring.
It works well for fish fries or crab/crawfish boils.
Step 1: Obtain Empty Keg Shell
Get yourself an empty keg shell. We live in a college town so I can pick these up from the frat houses for $5 or $10 each at the end of the school year.
Step 2: Cut the Top Out
I cut out a hole with a 4" cut-off wheel and use the lip as a guide. I cut out a hole large enough to work with while leaving a little lip inside in case I want to fashion a lid later on.
Be sure to release any pressure from the keg first by pressing the valve down with something hard. Watch out for spewing beer!
Step 3: Valve Removed
Here it is with the top and valve removed.
Step 4: Attaching Shell to Burner
I used stainless hose clamps to attach the keg shell to the burner frame through the four built-in drainage holes in the shell lip.
Here is an older frame that fit so snugly into the keg shell I can't get it out now.
