This page describes the steps to making a basic wedge T-fold.

To begin with a loop is made from a rectangular piece of sheet metal.
The loop is placed into the vise and the jaws clinched tight onto the loop. You can see the angle the loop is tilted to in the vise. Vary the angle to alter the results. Note this is also a very quick way of making a conical form in metal
The end of the loop is now malleted down, ‘confirming’ the position of the table relative to the legs. Clinching the end first leaves a hollow shape to the rest of the loop. This is called a pillow, and is used to chase into or otherwise work with. For a basic Wedge T-fold it is simply flattened.
Here is what the Wedge T-fold looks like after flattening down to the top of the vise. Note the protective vise jaws of copper which protect the fold being made. Other vise jaw materials such as plastic or wood can be used instead.
This is another type of wedge T-fold using a narrow rectangle and a more extreme angle in the vise. The change in shape and position leads to different forming options. Each change you make in the procedure results in variations in form.

Here is an example where the table returns have been unfolded, arching over the table surface.

This is a wedge T-fold which has had the table returns completely unfolded, and then been flattened ‘confirming’ the two fold edges from the table sides, making them into line folds.
