Step 1
Measure where you will cut your pipe. Use a speed square and pencil to mark your cutting line.
Step 2
Place your pipe into the miter box. Align the pencil mark with the appropriate slot in the miter box.
Step 3
Insert your saw into the slot of the miter box. Use a saw blade rated for PVC or metal, depending on what you are cutting.
Step 4
Slide the saw back and forth across the pipe to cut it. Use slow, even strokes to ensure a smooth cut.
Step 5
File the edge of the pipe to remove rough edges, if necessary. Metal pipe will require filing, while PVC will not.
