Making the Wooden Hinged Table Leaf Support
So far in this series on the Breakfast Table, we’ve done the rule joint, legs, and pierced carved skirt. In this post, I will show how to make the wooden hinge for the leaf support.
The final wooden hinge is shown in this illustration with the Top hidden. Note that there is a fixed full length rail that is tenoned into the legs. The hinge is made up of two pieces, one half of which is glued to the fixed rail.
Step 1: On the framework of the four legs and the pierced skirts (created in the last post), create the fixed full length rail. As we’ve encouraged often, it is preferable to create new parts within the existing assembly. Therefore, the full length skirt component is developed between the existing legs.
Here is a close up of the final hinge pieces for reference as we create them from scratch.
Step 2: Begin the fixed half of the hinge within the context of the assembled table. Create the upper face of this hinge half which includes a corner made from a 3/4-in. diameter circle. The hinge center is at the midpoint of the distance between the legs.
Step 3: Using the upper face created above, develop the hinge width and begin the layout of the knuckles. To create the gaps in the hinge, I’ve used cutting planes spaced evenly and the Intersection function.
Step 4: After the Intersection, use the Eraser Tool to clean up the waste. Also use the Circle Tool to create the hinge pin. Again use Intersect to create the intersection of the pin with the knuckles.
Step 5: We can use the fixed hinge half just created above, to speed up the development of the moveable hinge half. Copy the fixed half, move to the right, flip along the appropriate axis, and move into an offset position as shown below.
Step 6: With three simple steps we can quickly make the required adjustments to the right half of the hinge.
Step 7: However, there is one more adjustment to be made. The moveable portion of the hinge must be rounded on both outside corners. Use the Circle Tool to create the missing corner arc.
Step 8: Use the Push/Pull Tool to remove the square corners.
Step 9: The moveable portion of the hinge is nicely shaped as shown below.
Step 10: Place the two halves of the hinge into the table assembly. Copy and use the Rotate Tool to place the hinge on the other side of the table.
