| Aluminum Tank |
(click for larger image:)
| Everyone needs a tank some times. Often the tanks available just don't fit one's needs. |
| The aluminum sheet for this tank was .090. I believe the aluminum is 3033. |
| First step is to determine
the dimension of the tank. Let's say the tank is 5 inch diameter by 7
inches tall.
The round top and bottom will be 5" diameter circle of course less about 1/8". 4 7/8. The smaller circle allows a gap in the corner to weld. This will allow you to grind the weld smooth. The side is rolled from a square piece which is 7 inches by the circumference. Circumference = the Diameter x Pie. Pie is 3.1416 5 x 3.1416 = 15.7 So the side is cut 15.7" x 7" Simple enough. |
| This comprises of the top, bottom, side which is rolled and a cap/bung. | You can anneal the aluminum with a torch before rolling but you don't have to. |

| If you don't have a roller a pipe works fine. | Top and bottom welded on and grind down. Finished with an abrasive wheel. |
