Slot Mortise: A Complete Guide
A slot mortise is a type of woodworking joint that is used to join two pieces of wood together. It is created by cutting a slot in one piece of wood and then inserting a tenon (a projecting piece of wood) from the other piece into the slot. The tenon is then secured in place with glue and/or nails.
Slot mortises are a strong and durable joint that can be used in a variety of woodworking projects. They are particularly well-suited for joining pieces of wood that are of different thicknesses or that have curved edges.
How to Cut a Slot Mortise
To cut a slot mortise, you will need the following tools:
-
A saw
-
A chisel
-
A mallet
-
A drill
-
A drill bit
-
A square
-
A marking knife
-
A pencil
-
A piece of scrap wood
-
Mark the mortise location. Use a square to mark the location of the mortise on the piece of wood that will receive the tenon. The mortise should be the same width as the tenon and about half as deep.
-
Drill a pilot hole. Use a drill and a drill bit that is slightly smaller than the width of the chisel to drill a pilot hole in the center of the mortise mark.
-
Cut the mortise. Use a chisel to cut the mortise. Start by cutting a shallow groove along the inside of the pilot hole. Then, work your way around the mortise, deepening the groove until the mortise is the desired depth.
-
Clean up the mortise. Use a file or sandpaper to clean up any rough edges on the mortise.
-
Cut the tenon. Use a saw to cut the tenon to the same width and length as the mortise.
-
Glue and assemble the joint. Apply glue to the tenon and mortise and then insert the tenon into the mortise. Use a mallet to tap the tenon into place.
- Secure the joint. Once the glue is dry, secure the joint with nails or screws.
