  1. 1

    Cut eight 2-foot-long pieces of 2-by-4 with the circular saw for the steps of the ladder. Leave two pieces at 10-foot for the sides.

  2. 2

    Sand all rough edges off the eight cut pieces and the two 10-foot pieces. Apply wood stain or paint and allow to dry. Next, apply water sealant to all ten pieces.

  3. 3

    Lay the two 10-foot 2-by-4s on edge parallel to each other 2 foot apart. Lay a 2-foot piece on the wide edge in between them so it runs perpendicular. Place it 6 inches inward from one end of the sides. Drive 3 screws through both 10-foot sides into the ends of the 2-foot piece.

  4. 4

    Lay another 2-foot piece on the wide edge in between the sides 6 inches inward from the other end. Drive 3 screws through both 10-foot sides into the 2-foot piece.

  5. 5

    Equally space the remaining six 2-foot pieces between the top and bottom steps and screw them to the sides. Make sure you use 6 screws for each step, 3 on each side. Stand your ladder up.

Tips and warnings

  • Adjust the 10-foot measurement for the sides of the ladder to make the ladder a different length.
  • Be cautious when using power tools.
