Cost
If you would like to build a library to support your local community, below are the bill of materials and plans to complete your library. The full sized library stands 2 feet wide by 4 feet tall. If you choose the most cost effective route (making three from one sheet of MDF), the base material cost for one library is approximately $105. Any printing costs for a sign would be extra.
There will be other incidentals such as glue, screws, and thumb tacks which are each a minimal cost and can be used over multiple projects. You may also have expenses for painting supplies such as rollers, brushes, and drop cloths, depending on your specific situation.
Wood
Libraries are made out of 3/4" MDF (medium density fiberboard). If you purchase pre-cut "quarter sheet" (2ft x 4ft) MDF from a store like Home Depot, you can complete one library with two pieces. One sheet will be the vertical "face" for the library, and the other will be cut into the base and supports. Each piece costs $30 ($60 total).
If you would like to assemble multiple libraries at once, the most cost efficient option is to purchase a full sheet of (4ft x 8ft) of MDF. One sheet of MDF can build three complete libraries. The full sheet can be cut into four 2ft x 4ft pieces. Three of those pieces will service as the vertical pieces, and the fourth will be used to provide all of the bases and supports for the three libraries.
One full sheet of MDF costs $50, putting the wood cost per library at $12.50. This is a significant savings over building one library with two quarter sheets, and results in far less material waste.
Shelves
The clear acrylic shelves used for the library can be found on Amazon. We used one set of three 21" shelves. The set of three cost $56. We also produced a narrow version of the library that was only 18" wide. For that library we used this set of 16.5" shelves. That set comes with four 16.5" wide shelves, and cost $60.
Paint
To ensure good paint coverage, you should both prime and paint the library. A white primer should be used for white or light colored libraries. A grey primer should be used for black or dark colored libraries. You should be able to fully paint one library with a quart of primer and a quart of paint. A semi-gloss is recommended for durability.
We used "Rust-Oleum Painters Touch Ultra Cover" paint, and Rust-Oleum primer. Each costs $18 per quart. We used their standard black and white colors for base coats. For the barber pole stripes we used the pre-mixed "Apple Red" and "Deep Blue". They made perfect barber pole stripes. The paints are a water-based acrylic.
We GREATLY encourage using a full size smooth roller cover for priming and base coats. We initially tried with "mini rollers". The full sized rollers produced better results (more even coverage and fewer drips) in FAR less time. Full size roller covers are also easily cleanable, reducing waste and cost. Smaller 4" rollers and roller covers work well for stripes.
Designs and stripes are easy to paint. Below we should how we painted barber pole stripes for one library.
Sign
A sign can be created in any image editing software like Photoshop Elements, Pixelmator, or any number of free programs. The sign should be about 20" wide by 6" tall. For good print quality, it should be created at 300dpi. The sign can be printed and laminated at Office Depot or a FedEx with print department.
To affix the signs, we used these large clear flat thumb tacks. They "disappear" once installed. We were able to push them into the MDF by hand, without the use of any tools or pre-drilling. I box of 150 thumb tacks cost $5.
Dimensions & Assembly
The base is 9" deep (front-to-back). The vertical "face" of the library is attached 3" from the back of the support (see pencil mark on the edge of the base).
The base is attached at this spot, as we are more concerned with the library tipping forward from the weight of the shelves and books, and from the force of people handling the books. Placing 2/3 of the base to the front helps ensure proper balance.
The front two supports are 2" tall and 1" tall. The back two supports are 3" tall and 2" tall. These supports provide a firm and stable "foot" for the library face to attach to the base.
Assembly is done by "gluing and screwing" the library face and supports to the base (from the bottom), and into each other. Simple wood glue, such as Tight Bond, works well. The library should be assembled with #8 drywall screws, 1 3/4" to 2" in length.
First, the library face should be secured to the base. From there secure the first back support to both the base and the library face, then secure the first front support. Continue alternating with the second back and front support. Each support should be secured to the base and to the neighboring support/face. Don't forget to use glue for each pair of wood surfaces that come into contact.
Tips: Use hand clamps to hold each support to the face and base while securing with the screws. For best results, and to prevent splitting the edges of the MDF, be sure to pre-drill all holes. Wood glue can be spread into a thin layer using a 2" foam paint brush.
To ensure proper alignment of the library face to the base, draw a line across the bottom of the base and around the edges. This will help ensure proper alignment of the pieces, and of the screws. Be sure to wipe up glue that squeezes out of the joints.
Holes for the bottom shelf are spaced 6" from the top of the support. The holes for the middle shelf are 14" above the bottom holes. The holes for the top shelf are 14" above the holes for the middle shelf.
It is suggested that you drill all holes prior to painting. This will ensure you don't scuff the paint when drilling. The screws included with the shelves are too long, and the ends will need to be cut off on the back side with a Dremel.
Counter-sinking screw holes is not necessary. After final assembly, fill all screw holes with putty prior to painting.
Painting Barber Pole Stripes
Step-by-step guide on how to paint barber pole stripes on a library.
This white base provides an even base layer, and will be the white stripes in the final product.
Make marks across the top and sides at 6" inch intervals. Be sure to mark and drill the holes for the shelves prior to painting.
Connect the marks with tape as shown, alternating a white stripe and tape. For the bottom edge you will need to measure up from the bottom-right, and transfer those measurements to the bottom. The actual bottom edge is hidden by the base supports. Finally, tape the entire base.
Alternating white spaces, paint the red stripes. You will likely need 2-3 coats for a good dark red. Be sure to paint the edges.
When you tape for the previous step, make sure you wrap the tape around the edges.
Paint blue in the remaining white spaces. Again, you will likely need 2-3 coats to ensure a proper dark blue.
Again, be sure to paint the edges.
Peal off all the tape, revealing the white stripes and the white base. Finally, attach the shelves and your sign at the top.
Beautiful!!!
