My desk at work is designed to hold a giant CRT in the corner. But in the 21st century, bulky vacuum tubes were replaced with wafer-thin flat screen displays. While this frees up plenty of valuable desktop real estate, it's hard to reach into the deep corner behind the display. I decided to add a lazy susan back there to hold my reference books. The bottom shelf is 18 inches in diameter and 11 inches high, so it can hold large books, and the top shelf is 16 inches in diameter, with a 6 inch "fence" to corral the smaller books. The project is also suitable as an exceptionally pernicious step stool.

Step 1: Tools and Materials

I used a router, saw, and drill to construct this project. Plus glue and clamps. Lots of clamps. You could probably do it without the router, but I used it to cut out the circles and the mortises. You'll need a basic set of twist drills, plus a 3/4 inch spade or forstner bit.

The basic components of the project are:

2 16 inch wooden disks (the base and top shelf)
1 18 inch wooden disk (the bottom shelf)
1 6 inch lazy susan ball bearing assembly (500 lb rating)
3 ft 1x4 stock for 3 "pillars" to support the top shelf
3 ft 3/4 x 3/4 stock for the top cross-piece
3 ft 3/8 inch dowel

You should be able to find these parts at the local hardware store or home center. Some of them even sell pre-cut wooden disks in plywood or laminated pine. The plywood is strong, but the edges don't finish up that well. I cut my own disks out of some 3/4 inch laminated pine sheet, which was cheaper than getting pre-cut disks, and the rest of the stock is poplar.

A note on cutting disks: if you don't have some sort of circle cutting jig for a router or band saw, don't try to cut out circles. You'll bodge it up. Just make some octagons instead.

And a final note on the lazy susan: it might seem ridiculous to use a 500 lb rated turntable for a little desktop bookshelf, but they're not expensive, and the main criteria is that the base plates have screw holes that are large enough to hold some decent wood screws, and they are spaced widely enough that the screw heads won't collide when the plates rotate. Also, keep the hardware packed away, so it doesn't get dusty. Any grit or sawdust in the ball bearings will impede smooth rotation.
I have always thought I wanted a lazy susan for books, but have contented myself with bookshelves and bookends over the years. The advantage of a round lazy susan for books is that there are no corners to catch on anything when it revolves. The disadvantage is that some books lean in a strange way that invites them to fall out of the lazy susan. I have always thought the ideal configuration for a lazy susan bookholder is that of a swastika, whether in the German pattern (arms radiate clockwise) or the Swiss pattern (arms radiate counter-clockwise). A swastika pattern does leave corners that can catch something moved too close to the bookshelf. Lest a swastika seem too politically incorrect, I have a commercial CD case that is actually a swastika configuration, but has a top on it so you do not see the swastika layout. Your is nicely done. Thank you for it.
A swastika (in plan) arrangement does seem to make a lot of sense. If you place it on a disk, and position an imposing sculpture of an eagle on top of it, other objects will stay out f it's way, and the corners won't be an issue.
I am sorry, but I do not know what else to call the pattern but a swastika. It would not be placed onto a disc, but the base of the bookholder would be square. It yields four open spaces for books to fit neatly with no unused space. As concerns a sculpture of an eagle, I am not going there.
Yeah, I'm only joking. A swastika shape or some variant of it would be good, especially if the object is to be placed not directly behind but behind and to one side of the monitor slightly. That way the only part of it that could be seen readily would be the compartment that faces you.
A very good idea!
