Thank you all.

Yes, guilty as charged! I did teach woodworking for a while. Now I teach Construction, so I still have access to the machines. No, Steve, I didn't use any tongue & groove joints; the multiple angle miters just about taxed my abilities to the limit. What looks like dowels in the pictures are actually the counterbore holes for the 2 1/2 inch drywall screws. All joints are glued and screwed.
