Stainless steel heat deform on purpose
I have a stainless water tray that is about 3' square and 2" deep. it has a drain fitting not quite in the middle. the fittings for the drain are about 3/16" thick and when the tray drains it leave a lot of water inside it to clean out manually with vacuum cleaners or rags. I know from past experience that if I heat stainless with a torch it will deform in the direction the heat is being applied. I wondered if I put a round weight, like a barbell disk in the middle of the tray then heat a circle around it from underneath if I could get the tray to sag a little bit evenly around the drain so it doesn't trap so much water? or am I headed for a lumpy uneven mess if I try this?
