Corner Bridle Joint

A corner bridle joint is similar to a mortise and tenon and is used to join two rails at the corner. It has all the strength associated with this type of joint, which is derived from the large glued area. The tenon is generally one-third of the thickness of the wood being joined.

1 Lay one rail on top of the other at 90° and mark the width of the top rail on the lower one. Use a try square to extend this mark, and project it around all four sides. On the edges, use a mortise gauge to scribe lines between the drawn line and the end of the piece, for the width of the housing. Cut down the vertical sides along these lines with a tenon saw. Use a power drill fitted in a drill stand to remove the waste. Make a hole with a bit the same size as the width of the housing; this will remove the majority of the waste, but will leave a small amount in the corners to be removed with a bevel-edged chisel.

2 Mark the second half of the joint in exactly the same way as a tenon is made for a mortise and tenon joint. Try the joint for fit and adjust if necessary.
