Preparation and Safety Guidelines

Tools Needed
  • 24-inch by 28-inch particle board
  • Table saw

  • Paint (outdoor use)
Safety Guidelines
  • Ensure the playing field is level and free of rocks or other hazards to prevent injuries from falls or trips.
  • Use appropriate materials for bases and the pitcher's mound that can withstand wear and tear and provide sufficient stability. Avoid materials that could become slippery when wet.
  • Always prioritize safety. Consider adding warning markers around the field boundaries, especially if it’s near obstacles or traffic areas.

Step-by-Step Instructions

  1. Prepare Base Material

    • Cut the particle board into a 24-inch by 24-inch square.
    • Set the table saw fence to 12 inches and cut out three 12-inch by 12-inch bases.
    • Cut the leftover scrap into a 15-inch long piece (approximately 4 inches thick) for the pitcher's mound.

  2. Prepare Home Plate

    • Cut a 15-inch wide piece from a new board for home plate. Mark out the home plate shape (approximately 8 inches from the center to each edge).
    • Cut out the home plate shape using a table saw (initial cuts can be done by scoring the material). Use a hand saw for the more intricate cuts.

Tips

  • Use inexpensive particle board for ease of cutting and cost-effectiveness.
  • Always sand the edges to prevent cuts.
  • Use outdoor paint to protect the bases from water damage.

Common Mistakes to Avoid

1. Incorrect Base Dimensions

Reason: Using the wrong size or shape for the bases can lead to an unplayable field and inaccurate gameplay.
Solution: Carefully measure and cut the bases according to official Little League or MLB regulations, using a template if necessary.

2. Improper Mound Construction

Reason: An uneven or unstable mound creates an unfair advantage or disadvantage for the pitcher and can cause injuries.
Solution: Use a level to ensure a perfectly flat and consistent surface, and compact the soil thoroughly for stability.

3. Neglecting Drainage

Reason: Poor drainage will lead to a muddy, unplayable field after rain, and can damage the base materials over time.
Solution: Ensure proper grading and drainage around the bases and mound to prevent water accumulation.
