Building a Test Tank
Here is a design for a test tank from the Young America racing syndicate.
- Safety Glasses
- Hammer and saw
- 2 sheets of 3/4 inch plywood
- 2 pounds of 2-in galvanized plasterboard screws
- Adhesive caulking
- Rubberized latex paint or enamel boat paint
- 3-Speed fan
- Don safety glasses
- Measure and cut the sides, bottom, ends, and supports from the plywood, using the diagram for reference.
- Join end to end the 8-ft lengths to the 4-ft lengths of plywood, using plywood scabs that measure 6 x 12 inches for the sides (F) and 6 x 24 inches for the bottom (G).
- Caulk the edges of each piece and screw them together to assemble the tank.
- Add corner gussets (H) measuring 6 inches per side to the upper for corners of the tank.
- Add the three bottom supports (I).
- Add a support platform for the fan. Use one 24-inch square piece of plywood. Support it with two 42-inch cantilever beams.
- Caulk the seams of the tank. Let it stand over night.
- Apply several coats of paint to the inside of the tank.
- Place the tank on a level surface that is strong enough to support the weight of the tank when it is filled with water. Some tanks are supported on 4 saw horses.
- Fill the tank with water, rest the fan on its support 10 inches from the tank edge.
Caution: Take the necessary precautions when the tank is in use.
