Achieving Tight Mortise and Tenon Joints in Windsor Chairs
A guide to creating tight joints in Windsor chairs, with a focus on the mortise and tenon joint.
The mortise and tenon joint is a fundamental component of Windsor chair construction. When executed correctly, it provides a strong and durable bond between the pieces of wood.
## The Importance of Joint Alignment
The mortise and tenon joint works best when the force applied is pushing along the tenon, rather than side to side. This is evident in the design of a Windsor chair, where the legs are positioned to withstand the force of sitting straight down the tenon. In contrast, the back of a side chair requires a different approach, with the spindles positioned behind the line of the bow to counter the force of leaning back. By bringing the bow forward 50mm, a triangle is created, allowing the force to be transferred down the spindles as the chair is leaned back.
## Achieving the Perfect Fit
When assembling a chair, it's essential to strike a balance between a tight joint and one that is too tight. A joint that is too tight can make disassembly almost impossible, while one that is too loose can compromise the structural integrity of the chair. The ideal scenario is a "push fit," where the joint is snug but still allows for easy disassembly. To achieve this, it's crucial to cut the tenon in a way that allows for a smooth fit into the mortise.
## Tips for Working with Mortise and Tenon Joints
* Always cut towards the vice, not side to side. This will help to prevent the work from moving in the vice and ensure a more accurate cut.
