Add Protective Stair Railing to an Existing Staircase while Preserving the Rustic Character of Its Heavy Pine Construction

Stay in step with the rustic character of your existing staircase by adding wood stair railing that mirrors its heavy pine construction. Assembled with groove-and-tenon joints and dowels, the sturdy handrail and square balusters of this simple project's design complement the roughhewn staircase while adding safety for young and old, alike.

Trace the Post and Cut Its Shape from the Tread
Step 1

Trace the Post and Cut Its Shape from the Tread

Position the newel post and trace a cutline around the post on the stair tread. Drill the four corners of the cutline to make starter holes, insert the blade of a jigsaw into the first hole and excise the shape.

Insert the Post in the Hole and Countersink Bolt Holes
Step 2

Insert the Post in the Hole and Countersink Bolt Holes

Insert the post through the tread hole and down to the floor. Ensure it is plumb with a post level. Countersink holes through the post and into the riser, and then bore smaller shank/clearance holes inside those for the bolts.

Insert Carriage Bolts and Secure with Washers and Nuts
Step 3

Insert Carriage Bolts and Secure with Washers and Nuts

Insert carriage bolts through the post and secure with washers and nuts on the opposite side of the riser. Cover the bolt heads with glued wooden plugs cut from dowel rods. Tap gently with a hammer to seat the plugs.

Clamp the Two-by-four Railing to the Post and Ceiling
Step 4

Clamp the Two-by-four Railing to the Post and Ceiling

Determine railing elevation from the stair tread. Measure with a tape measure attached to a bar level. Clamp the rail to the post and ceiling beam at the correct elevation on the second step and one of the upper steps

Trace the Bottom Angle of the Rail around the Post
Step 5

Trace the Bottom Angle of the Rail around the Post

Trace the bottom angle of the railing as a cutline around the perimeter of the post top. Draw a second parallel line below it for the post's tenon/tab. Cut the tenon for the post top with a Japanese handsaw.

Route the Groove on the Underside of the Handrail
Step 6

Route the Groove on the Underside of the Handrail

Route a groove on the bottom of the handrail to receive the tenon on the post top and the tops of the balusters. Two passes through the router are required to make the groove wide enough to accept them.
