    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?

    Is the fitting a mounted one or is it welded to the tank and what diameter is it?

    The fitting is a brass affair with 1/4npt threads and a big nut and rubber washer holding into a punched out hole. the hole doesn't have a beaded edge or anything it's just a flat hole. I should also mention that the perimeter of the bottom face is bolted in to a square frame. i'm thinking that part will stay parallel and thats ok the rest of it i'd liked dished down

    Tried this. Was able to drop the table base about 1/8 only as the metal mostly shrank back. I'll need to shape this a diferent way or just make a new one. Can stainless be shaped like a car fender? Like can I get the metal the flow with a hammer and dilly for example?

    Tell me and I forget. Teach me and I remember. Involve me and I learn.
