Building the Base (finished piece #1 and #2):2. On your base, measure and mark a line with a pencil 3/4" from both sides and also one directly in the middle of the piece.
3. Glue the long side of three divider pieces to the base where youve made your marks. Use a nail gun to secure the dividers to the base from the underside (figure A).
4. Take one 54" x 17-3/4" piece and glue it to the top of the dividers, making sure there is 3/4" on either side. Nail in the top with a nail gun. Drill pilot holes with a countersink bit, then secure the top piece on to the dividers with screws. This is your finished piece #1 (figure B).
5. Repeat steps 2 and 3, but substitute a 54" x 17-3/4" piece as your base. Let this section dry completely. This is your finished piece #2.
