I started building the built-in bookshelves that go into basement. The diagram here shows where the first set will go.
The unit will be 7 feet tall and 8 feet wide. There will also be two more units of hte same design at the other end of the basement. These will each be about 3 1/2 feet wide. Here is the concept from the computer model of the house:
I was cut the uprights out of 1/2 prefinshed (on one side) plywood that was left over from our kitchen cabinets I built. We are painting these, so I turned the finished side outwards. The shelves are out of 3/4 hardwood plywood.
I used a one foot speed square to lay out the lines for the shelves. I always make an X mark on the side of the line where the shelf goes, so I don't get confused later on.
I decided to route 1/8" deep dadoes into the uprights to make assebly easy. My initial plan was to just glue and screw the shelves together, which would give plenty of support. The downside of this is that I would have to hold each shelf exactly square. Dados provide easy alignment, so it was worth the extra effort.
Here is the jig I built to simplify the routing...
The jig works with my trim router. Sincne these dadoes are only 1/8" deep, it cuts them easily. Whenever possible, I use the trim router instead of a larger one, since it's light and easy to handle with one hand. Also, this one cost me $20 at Harbor Freight on sale (been going strong for 3 years), and it's the one I want to use up.
Here is a completed upright. Now on to mounting the shelves...
