There are several steps required to make the curved cabinet doors required for the custom design shown on the right. What complicates this design is that the curved doors are also tapered. This makes the join line between the sides of the cabinet and the curved doors non-linear. The join line is further complicated because it needs to taper in to hide the end grain of the sides and the doors.
The first step is to make a curved panel that can be cut to the required shape. The only way to make this is to make a form that has the same radius as the door, and laminate several sheets of 3 ply together inside the form.
The glued sandwich of plywood is placed into the form and clamped in place with heavy weights until the laminate dries. When the panel is removed it is the same shape as the form.
The following photos illustrate the steps involved in making the curved cabinet doors panel.

Routing the radius for the curved panel support frame. This will make the curved panel easier to handle.
The next step is to cut the two doors and drawer fronts from the tapered curved panel. This requires a special jig to be built so the elliptical curve between the sides and the door can be accurately cut. These in turn will need to be held in position for the mating of the side panels and central hinge support. The next blog post will illustrate the steps involved in this process to make the curved cabinet doors.
