Step 17: Secure spindles

On the 2"x6" board, find the center and mark a line every 5 inches from this point. Center and attach the 2"x2" spindle to the 2"x6" rail board at every mark, using only one 2 1/2" deck screw at the top. With a level, plumb (vertically level) each 2"x2" spindle and attach a 2 1/2" deck screw into the deck frame. After 2"x2" spindles are positioned, attach a second 2 1/2" deck screw at the top and bottom of each spindle. Typical building code requires a space no greater than 4" between spindle openings.

Tip 1: Verify that all 2"x2" spindles are exactly the same length. It is common for spindles to be slightly different lengths. If they are different lengths, a jig can be used to quickly cut all 2"x2" spindles to the same length.

Tip 2: Pre-drilling 2"x2" spindles will help reduce splitting of the lumber. Determine the locations for the deck screws and pre-drill two holes at both ends using a counter-sink bit. All 4 deck screws can be "started" before attaching to the railing and frame.
