At the same time as I bought material to make a small stand for my Father, I bought material to make this as well.
The belt sander makes quick work of evening out the boards and getting the shape I want.
I was upset earlier with the mistakes I made, but seeing this together now has made me all happy again.
The only downside at the moment is that the longer shelves are now wider than the verticals. I could trim a little bit off of each shelf on the table saw, but it honestly doesn't look too bad to me. Plus, I want my mother to have plenty of room on each shelf for her Legos, so the shelves can protrude a little.
The final result was a very awesome looking wall shelf.
Now all that's left is to give it to my mother for Christmas and hang it in her house.
My mother will have to use a step stool to reach the upper shelf, but she was fine with that. She loves her new shelf and that makes me happy.
