The frame is to hold the TV screen. The particle board will be the bottom layer of the table itself. I wanted the screen slightly offset from center to give the "DM's end" a little more room. We then traced where to cut an opening for the frame.
Once the hole was cut, we put he frame inside. It was a pretty tight fit, but that's good! The, because particle board doesn't have a lot of structural strength, we glued and screwed two 2x4's on either side. these will also be part of the frame that holds the top layer up and divides up the 'cubbies' that the players can use for books, etc.
At this point in the afternoon, we need to let the wood glue dry and there was food to cook and children to ferry to activities. The next steps should go fairly quickly, as we'll just be cutting and attaching lengths of 2x4's to complete the framing. After that, we'll work on the top of the horizontal surface. I also need to cut out the corners of the particle board to make room for the table legs.
