L-joints: Six Ways to Make Corners

 

Avoid elaborate joining of projects which are to be painted or where the appearance of the construction does not matter.

Modern glues, with screwing or dowelling, make strong corner joints. Six methods are shown on the right. The top three rely on corner blocks and the bottom three on metal or wood corner brackets.

The wooden corner blocks can be square or triangular in cross-section. The triangular shape [1]gives a neater appearance on the inside of cupboards.

The strength of these joints relies mainly on the glue; in addition to being glued, they should be nailed, dowelled or screwed together.

Hammer nails home dovetail-fashion. Stagger dowel or screw holes to avoid splitting the cross-piece along the grain. Make sure the dowels or screws do not meet in the middle.

Metal brackets can either be let into the top and bottom of the corner [4] or screwed straight on to the inside of the joint [5]. The first method is the stronger.

Metal brackets must be painted to prevent rust.

Triangular plywood brackets , also fitted top and bottom, are glued and pinned to the corner. Trim the outside edges when the glue has dried.
