The Box - Part 2

I made some progress on Harry's box today. It was a nice day and I felt like being outside, but I really wanted to get something done on this project, so I spent most of the day in the cellar until we went in the pool, then the spa, then back in the pool (me). I can't believe I did that. Anyway, the box is coming along. I put together the ___ and now I have to fit the ____to it. Then I need to complete the ___ and the ___. After that, it's just a matter of making and fitting on the top.

 I'm sorry I had to leave blanks in the narrative above, but it is a secret box, after all. If I revealed how I made it, it wouldn't have any secrets to it.
