What joinery is best for fitting the door stiles to the rails for a curved china door cabinet?
Andy Rae: A bridle joint, which is an open mortise-and-tenon joint, is probably your best bang for the buck. It’s plenty strong for heavy glass doors, and it’s easy to cut the open mortise in the stile on the table saw using a tenoning jig.
Kevin Hancock: Mortise and tenon.
Richard Jones: Mortised stile and tenoned rail is probably the most common in traditional work. You could also use slip tenons or dowels, and modern commercial cabinet doors are made with matched door rail and stile cutter sets.
