Things You'll Need
- 3 digital bathroom scales
- 4-foot-long 2-by-4s, 4
- 21½ inch long 2-by-4s, 2
- ½ inch exterior plywood cut to 2-by-4-feet
- Screws
Instructions
Screw two of the 4-foot and both of the 21-½-inch-long 2-by-4s together to create a rectangular frame.
Screw the remaining 4-foot-long pieces horizontally into the frame to create interior supports.
Screw the square frame to the exterior plywood to create a platform. Set aside.
Place the scales on a level, hard surface such as cement, making sure they are evenly distributed.
Overturn the platform and center it on top of the scales.
Remove the platform and quickly check the weight values on each of the three scales. Total these three numbers and make a note of the total.
Place the animal evenly on the platform.
Remove the animal from the scale and add the values of the scales together for a total weight. Subtract the weight of the platform to determine the animal's weight.
