Easy, cheap, low-waste bookshelf plans

Build an easy, portable 3′ x 8′ wooden bookshelf in about 20 minutes, with a minimum of tools and less than 1% waste, for about $60. The basic concept can be modified to create any size shelf system needed.

Step 1: Tools and Materials

You will need:(4) 8′  1×8  #2 and better pine (2) 12′ 1×4 #2 and better pine (16) 9-3/8″ long pieces of 1/4-20 all-thread rod (about 13′) (32) 1-1/4″ fender washers (32) 1/4-20 “acorn” or “cap” nuts (1) 1/4-20 wingnutMy material cost was: Lumber $39.62 Hardware $18.24 Total: $57.86Hand or power saw for wood Hand or power saw for metal (You can often have these items cut for a minimal fee at your local lumberyard) Tape measure Square Pencil Drill 9/32″ drill bit for wood Two 7/16″ wrenches, or two adjustable wrenches, or a 7/16″ wrench and a 7/16″ socket and driver Optional: Awl, nail, or centerpunch

Step 2: Measure, measure, mark, and cut

Yes, measure twice. As you can see from the photo, there is very little waste.Trim the 1×8 boards to 8′ exactly. From each of the 1×4 boards, cut (4) 35-3/4″ pieces for a total of (8) Cut the all-thread into (16) 9-3/8″ segments.Before cutting each section of all-thread, run the wingnut onto the rod. After cutting the rod,remove the wingnut over the cut end to “chase” (repair) the threads.You should also double-check the length of your all-thread rods. I’d dummy one up and try it out before cutting all of them. It needs to be just long enough to catch a couple of threads and snug down without punching out through the cap nut. The actual “cap” portion of cap nuts is fairly thin, and if the all-thread is even a bit too long it will punch through the end when you snug it up.

 

Step 3: Layout and drill

Lay out one of the 1×4 pieces for drilling:Holding the tape in your left hand, and hooking the end of the tape on the right-hand end of the board, mark:1″ 12″ 23″ 34″Next, mark 1-3/4″  (the center line) across the board at each previous mark, and use a nail, awl, or centerpunch to dimple the wood and guide the bit. Using the 9/32″ bit, drill completely through the 1×4 at the four marked locations. Try to keep the hole as straight as possible, although a high degree of precision isn’t necessary.

Step 4: Repeat

If you wish to have a more finished appearance (hah!) now is the time to sand, stain, and seal your work. It will be much easier to do it now, before the piece is assembled.

Step 5: Assemble

Place lengths of all-thread through the top and bottom holes on two pairs of 1x4s.

Place a washer and a nut on each end of each length of all-thread. Note: washers have a “belly” formed when they are punched out of the sheet of metal. Like a biscuit or cookie, the top edge is slightly rounded, and the bottom edge is a bit rough. Pay attention to the belly, placing the rough edge against the wood, and the smooth edge out. Pro.

Place the top and bottom shelves into position on top of the all thread, leaving 2″ extending out past the uprights. The uprights clamp or pinch the shelves in place, so gently snug the nuts down to keep it all together.

Assemble the other pairs of uprights in place around the top and bottom shelves, leaving 26″ between the uprights.

Fill all of the remaining holes with all-thread and loosely attach the nuts and washers.

Thread the remaining two shelves down the length of the unit, on top of the all-thread, and “snap” them into place.

A scrap block and a hammer may be necessary to “snap them” down.

Check the shelf assembly for square by measuring it for corner to corner. If the two measurements are the same, it is square.

Tighten all of the nuts, using, simultaneously, your tool of choice on each end of each rod. Just snug them up; it is not necessary to get them “gorilla” tight.

Tightening the nuts clamps the uprights against the shelves, holding them in place and providing shear strength (through friction) for the whole assembly.  Enjoy!
