I spent part of yesterday, and most of today getting the rabbets in the top, bottom and sides. I used my router and router fence attachment to make the rabbets. I also learned how my joining sucks. There were a few peaks and valleys where I had edge joined the boards. I need to do a better job of making sure the boards are joined and faced properly.
I glued up the back panel and let it dry, while I went to Lowe's to get some finishing supplies. When I got back I used my Random Orbital Sander (ROS) to sand all the pieces. I think it's finally ready to glue-up. My only question now is, do I finish it before glueing or after? I don't know either. Time to hit the forums.
