   I don't clamp 3-4 boards at once. Some do with a caul, but I find I get better flatness with two at a time.

   Use a caul, a 2x2 chunk of wood that goes across the top of the panels and is clamped down to keep them flat.

   Don't use too much clamp pressure--this is generally the main thing that I do that causes bow.

   You clamps should be in line with the work. If the clamps are too low, e.g., the center of the clamping face is below the center of the edge of the board, the panel will bow up; if the clamp is above center, the panel will bow down. Use a shim to center the clamps to the edge of the panel.

   Others will chime in, those are my suggestions.

   Regards,

   Scooter
