Bill of materials

The list below assumes all the lumber is of clear of knots and defects. You should buy extra wood to be able to cut around pieces with defects in them, as construction lumber is usually full of knots and other defects. Its best to buy wider pieces of lumber and then rip them to the right width. You end up with higher quality lumber that way, because the larger trees that the wider pieces are cut from tend of be of better quality.

Overview

Cross section

Note how the slats rest on the ledge on the inside of the side rails.

A rabbet in the end of the slats ensures that they don't add too much height.


Headboard

The holes for the dowels are best drilled by clamping the horizontal and the post together, and drilling the hole through both parts at once from the outside, as shown below.


Footboard

The foot board is nearly the same as the head board, just shorter. If you who prefer to stick their feet off the end of the bed, leave out the top horizontal part, and make the posts just 18" long.

Bed rail

The bed rail has a series of blocks on the ledge to support the slats. The purpose of these blocks is to hold the slats in place laterally.

Its best to glue and screw the 1.5"x1.5" support rail for the slats onto the main part of the rail, as all the weight is transferred through that rail.

Final assembly

The side rails are only attached on location. To move the bed frame, the side rails are unscrewed.

The slats are placed between the bed rails, and are not fastened in place. The blocks on the bed rails prevent them from sliding around.
