I am just about done with this one. It is a built in bookcase made from cherry plywood with a solid cherry face frame. It is pretty big at 7.5 feet tall by 41 inches wide. I still have to make the adjustable shelves but I just could not wait to post it. I need some motivation to keep going. The 3 coats of ply seemed to take forever to apply!
This was a challenging project for me given its size and the fact that I had to design it and determine all the dimensions. It was also the first time I had scribed a cabinet. Oh and I had to move an electrical outlet to one side that was right in the middle of the wall.
One thing I would do differently is use 1/2 plywood for the back instead of 1/4. It looks fine but it has that hollow sound to it when a book its it. I tried to save a buck.
