Q:

# How do you build a deck railing?

A:

To build a deck railing, secure rail posts to the corners of the deck and the middle of each side, and then attach 2-inch by 4-inch boards between each post to act as the top and bottom rails. Use a 2-inch by 6-inch board as a rail cap.

1. Cut the handrail posts

Determine the height you want each handrail post to be. Add 9 inches to that measurement, and then subtract 1 1/2 inches. Cut each post to that length.

2. Cut a notch in the handrail post

Use a circular saw to cut a notch that is 9-inches high and 2-inches deep at a bottom corner of the handrail post.

3. Attach the post

Slide the notch over the corner of a deck beam, and secure it with bolts.

4. Determine where the middle post must go

Measure the distance between the post and the next corner over of the deck. Divide the measurement by two, or divide by three if the measurement is more than 8 feet.

5. Trace an outline

Trace an outline for the post at that spot on the surface of the deck. The post must fit in a way that makes the outside face edge level with the face edge of the deck.

6. Cut and attach the middle post

Use a jigsaw to cut out the outline on the deck, and then use a circular saw to cut out the notch on the post. Bolt the post to the deck.

7. Cut the rails

Measure the distance between each post, and cut the top and bottom rails to this size.

8. Attach the bottom rail

Screw the bottom rail between the posts above deck level.

9. Attach the top rail

Screw in the top rail so the surface of the rail is level with the surface of the posts.

Repeat the procedure until every rail is up.

11. Cut rail caps

Measure each side of the deck from corner post to corner post. Cut each rail cap to this length, and cut a 45 degree angle at each corner.

12. Install each rail cap

Screw each rail cap into the tops of the rail.
