I used the bottom of an old coffee can as the pattern, started raising on a 2"ball, and took to completion on my 2" round stock T stake
you can see some of the inconsistencies in the thickness & roundness of the vessel
I had to trim this much off to make an uniform edge, which I deburred& sanded smooth, so far that is the extent of the finish work
btw I thought I had cut the disk from 16ga, but I think now it might be 14ga ...that was the thinnest on the rim
