Procedures

Step 1: Cut Materials

Cut stiles to x from material.
Cut rails to x from material.
Cut panels to x from material.

Step 2: Cut the Joinery

Grooves for the Panel

Use a router with a slot cutter or a table saw with a dado blade to cut a wide groove, deep along the inside edges of all stiles and rails.
The panel will slide into this groove.

Tenons on the Rails

On the rails, cut a tenon (tongue) thick and long on each end to fit into the grooves of the stiles.
You can do this using a table saw with a dado blade or a router.

Step 3: Dry Fit the Frame

Test fit the stiles, rails, and panel to ensure a snug fit.
The panel should fit into the grooves without forcing.

Step 4: Assemble the Door

Apply glue to the tenons of the rails (avoid getting glue in the panel grooves so the panel can expand/contract).
Insert the panel into the grooves.
Clamp the frame together and ensure the door is square by measuring diagonally.
Let the glue dry for at least 30 minutes to an hour.

Step 5: Sand and Finish

Sand the assembled doors smooth.
Slightly round over or chamfer the edges for a softer look.
Apply primer and paint or stain and seal.

Calculations

Each door will have a overlay on all outer edges and a gap between them.
