Raised Panel Cabinet Doors
I used to build cabinet doors in a custom shop. I have built many raised panel doors. You should have no problem making a door that tall without a center rail. The panel should be made slightly smaller than the inside of the groove of the frame to allow for expansion and contraction the width of the door. The panel should float in the frame. Therefore you should have no problem with the middle of the door bowing out. If you want to keep the panel from moving around in the frame you can shoot one 18gauge x5/8" pin nail angled towards the frame centered on the panel where the panel meets the frame. At the top and the bottom of the door frame. No nails should be used across the grain. The panel should be aloud to move across the grain. I would use three hinges.
