I'm thinking about loosely modeling the old water tank near the tracks in Sulligent. It would be an accessory to my 1:4 scale 4-8-2 smoker. I have a black, plastic, 55-gallon drum with a diameter of 24". Can anyone think of how I could make something to resemble the "bowl" shape underneath? I had my grandmother's old Weber grill that burned out in the bottom but I gave it to my neighbor for scrap. Now I'm kicking myself. It would have been perfect. Any other ideas?
