How to Construct an Indoor Pitching Mound

Inclement weather can make it difficult to practice baseball during the winter in many parts of the country. This can be a disadvantage for players growing up in northern states who need practice to keep their arms strong and to work on their pitches and control. Pitching in the cold can lead to arm problems and other injuries. A possible solution is building a pitcher's mount that can be used indoors.

Instructions

    • 1

      Saw four feet off of a 2x10x12 piece of treated lumber and set it aside to be used as a back brace. Take one of the 2x10x8 pieces of treated lumber and use a tape measure to make a mark at 24 inches. Proceed to make marks at three, four, five, six, seven and eight feet beyond the 24-inch mark. Beginning at the three-foot mark, use a square to place a mark one inch below the top of the board. Then mark two inches below the four-foot mark, three inches below the five-foot mark, four inches below the six-foot mark, five inches below the seven-foot mark and six inches below the eight-foot mark.

      Take a chalk line and mark the board. Following the line, use a skill saw to cut along the board. Use the cut board to mark the other two 2x10x8 boards and saw them. Once they are all cut, lay them on a flat surface.

    • 3

      Cut a front brace from the 2x4x8 piece of treated lumber. Screw the back and front braces onto the four cut boards.

    • 4

      Measure the plywood and cut a piece to fit the flat surface. Cover the sloping area with the rest of the plywood. Attach the plywood using 1 1/4 inch deck screws.

      Cut a piece of synthetic turf to cover the mound. Apply spray glue or contact cement to the entire surface of the mound before placing the synthetic turf on top of the mound. Once the glue or cement is dry, make a pitching rubber out of a 4x18 inch piece of scrap wood. The pitching rubber should be 18 inches beyond the center of the mound.
