Ben and Twilight: Thanks!
Over the weekend I got some countersunk screws. (Thanks for the suggestion, Beta.

I am done painting the back, hence items being glued in. Tomorrow I am selling lemonade with my younger brothers until maybe 4pm, so no updates till then.

Some other kids are selling lemonade and talking trash on our lemonade stand to potential customers. We're gonna do better than them.
