Things You'll Need:
- Steel pipes
- Pipecutter or hacksaw
- Vice
- Metal file
- Sports tape
- Juice can
- Whole grains
-
Step 1
Cut three 3/4-inch diameter steel pipes into 30-inch-long lengths. Hold the pipe steady with a table vise and use an electric hacksaw or pipe cutter to cut the ends as flat as possible.
-
Step 2
File the cut ends smooth with a metal file. When stood on end, the pipes should sit flush against a flat surface.
-
Step 3
Wrap the length of each piece of pipe completely in slip-resistant tape. Sports tape for hockey sticks and other equipment works well.
-
Step 4
Hold the pipes together in a tight bundle. Set the cut ends on a flat surface to ensure they are even. Wrap duct tape tightly around the entire bundle to hold it together.
-
Step 5
Cut the top off a large juice can or use a coffee can to hold the grain. Choose a can that is at least four inches in diameter and seven inches high.
-
Step 6
To use, fill the can one inch deep with the grain of your choice. Place the can on a hard flat surface. Sit on a chair and hold the can steady with your feet. Grip the pipe bundle at a comfortable height and set the cut end in the can. Lift the pipe up three inches and pound in short rapid strokes until the grain is the desired consistency.
