Every few years, I remember that the whole reason I started woodworking was that I needed to build bookshelves for my family. Some things don’t change.
When we moved into this house a year ago, we had big plans to turn our front room into a proper home library, complete with a whole wall of built-in bookcases. But as of last month, most of our books were still in boxes.
I spent much of the month of June turning this room into a real library, complete with something our whole family has always wanted: a rolling library ladder.

The house has 10-foot ceilings on the first floor, and this wall is over 12 feet long–a perfect place for a big bank of built-in bookcases. I just had to build them.
The Bookcases
My wife and I went over to the local hardwood dealer with a shopping list and a budget. My initial plan was to build it all out of poplar and add maple face frames to match the original maple trim in the room. But as we were browsing, we found a whole pallet of these:

They were drawer-side shorts and rejects–maple boards glued up with a groove near one edge, all between 3′ and 4′ long and 7″ to 9″ wide. At 5/8″ thick, they seemed good enough for the shelves. We bought as many of these maple shorts as we could, plus several 1″ thick poplar boards for the uprights.
It took some experimentation to get the shelves spaced out in the best way. I needed some space for tall books, and I also wanted all the books to have proper head-room while still having as many shelves as reasonably possible. I ultimately decided that the bottom two shelves would have 15″ of clearance for tall books. The rest of the shelves are about 13″ apart, which is enough for just about any standard size book. The very top has 12″ of clearance below the ceiling.
When doing any kind of big built-in, it’s best to build the whole thing in several modules, which you then assemble on site. You build them small enough to fit in easily and add trim to fill the space.
I built four separate shelving units that were 3 feet wide and 9 feet tall. Each unit had 8 shelves, seven of which were housed in dadoes and the last of which was merely rabbeted into the top and secured with both glue and nails. All the joints are covered by trim.

If you do an operation enough, you get a process down and it goes very quickly. I have cut many dado joints before, so the joinery went fast. I saw out the sides of the groove with my stair saw, which is set to stop at a particular depth (in this case 5/16″). You just keep sawing until it stops cutting and then go on to the next cut.

I use a chisel to knock out most of the waste, and a router plane levels out the bottom. If you have marked out the joint accurately enough, the shelf fits snugly into place. By the time this whole project was done, I had cut a total of 82 of these joints by hand, plus 20 rabbet joints.
I built the units one at a time so that I could clamp one up and let the glue dry while I worked on the next one. (Pro tip: always check each unit for square before the glue sets!) One by one, my wife and I carried the units up out of the basement workshop and set them in place.

No old house has even floors, so it took quite a lot of shimming to get everything straight and level. (My 13-year-old included for scale.) I screwed each side to the adjacent one and also used L-brackets on the very top to screw the cases to the wall studs.
I covered the gaps with maple trim, all cut from the same pile of maple shorts that gave me all the shelf pieces. I just cut apart the few panels that were already de-laminating or that had serious flaws and used the good parts for the trim. A coat of Danish oil finished everything off.
It was about this time that I realized I should have already ordered the hardware for the rolling ladder earlier. There were quite a few options online, but I ended up using the Rockler kit, which worked out fine. It was the least expensive option from online retailers that I was inclined to trust. But as any builder will tell you, the really expensive part of any cabinetry project is still the hardware. I spent about as much on the ladder hardware alone as I did on all the wood for the whole project.
Interlude: A Smaller Bookcase
While I waited for the ladder hardware to be delivered, I started to look around at another space in the room that seemed ideal for a bookcase. I counted up the maple boards I had left over and found I had enough for one more unit–if I was willing to build it in three pieces instead of just one.

This is the result. (And yes, that is a sprinkler head up near the ceiling. This house was a commercial property for a couple decades and still has a lot of features like exit signs and a fire suppression system.)
As I planned out this unit, I recalled a bookcase that Chris Schwarz had built years ago. He called it a set of Monticello Bookcases, which are essentially a bunch of long, stackable crates he made look really, really nice because they’re made from hardwood, dovetailed together, and set on a decorative base. While the construction method requires more wood than an ordinary bookcase (because each shelf is doubled up), it can be build from relatively short boards if necessary. It was a perfect solution for my own situation–I had a bunch of short boards on hand but no long ones.

Each unit was about 3 feet square. The bottom one is deeper than the top two. Construction was very simple–the middle two shelves are set in dadoes while the top and bottom shelves are nailed and glued into rabbets. A rabbet in the back of each one lets in a plywood back.
The rabbet in the back was the easiest part. Remember that my stock is all drawer side rejects? Each one has a groove near one edge. So I just ripped off the part past the groove and–voila! There’s a 1/4″ rabbet left on the back edge, perfect for housing a sheet of 1/4″ thick ply.
I set the bottom unit on a plinth in order to raise it up a few inches off the floor. I wiped on a couple coats of Danish oil finish, and once everything was dry, I stacked the three units in place and screwed them together. It was a very straightforward way to build a bookcase, and should I need to build a similar unit again, I will probably build it along the same lines.

Once the finish was dry, we very quickly filled it up with books.
The Library Ladder
Meanwhile, the hardware for the library ladder arrived. It comes with detailed plans for making a ladder out of wood you supply yourself. While the plans are good enough, I have something of an allergy to building anything from somebody else’s plans. (I have a similar aversion to teaching from somebody else’s lesson plans. I just can’t do it.) So I made some modifications to the plans, and I’m happy with the result.
The plans called for all 3/4″ thick stock, which looks a bit thin to my eye. I wanted a ladder that looked more robust. Also, the stability of the ladder in the plans depends entirely on the hardware, including rods and screws underneath every step. But I don’t like the look of a ladder side bristling with bolt heads. Plus, I know how to build a ladder that will stay together without a lot of extra hardware. I sketched out a modified plan and got to work.
I chose to use yellow pine, which is quite strong and very cheap. I cut out of some wide 2X stock I bought at the local home center.

You can almost always find a couple wide pine boards that have knots in the middle but have clear and straight sections near the edges. That makes for good uprights for the ladder. I cut around knots and defects in second board to yield the stock for the steps. I dimensioned everything down to about 1″ thick, taking care to remove approximately the same amount of material from each face.
The hardware is made to attach to thinner stock than I am using. (If you’re using the Rockler kit, do check the dimensions of each piece of hardware. The instructions will say everything is made for 3/4″ thickness, but it’s not perfectly consistent. You should always measure hardware yourself and dimension your wood accordingly.) So I shaped the ends of the uprights to accept the hardware designed for thinner stock.

That way, I still get the benefit of thicker uprights where it matters–where the steps dado into the uprights–while still being able to use this hardware designed to mount on thinner material.
In order to keep the ladder together, the bottom and middle steps, as well as the top rail, attach with a through-mortise and tenon joint.

This prevents the uprights from pulling apart and keeps the rest of the steps set securely in their dado joints.

Once the glue was dry and everything was trimmed, I gave the ladder a couple coats of the same Danish oil finish that I used for everything else, and then I attached the hardware. (One more note if you’re using the kit but modifying the plans: you might need to source longer bolts or otherwise plan to recess the supplied hardware should you opt to use thicker stock.)
Set in place, the ladder is strong and stable, and it rolls well even on our fairly thick carpet.

We have had to warn the kids, however, that this is a piece of furniture and NOT a Disney ride–whatever they may have seen Belle doing during a certain musical number in the animated film Beauty and the Beast.

The room has quickly gone from being a cluttered spare room to being one of the most comfortable, inviting rooms in the whole house.
