Single sheet of plywood bookcase
My goal with this bookcase was to maximize a full sheet of 3/4" plywood. The design I came up with does just that. There is very little scrap lumber left over.
I also included room in that sheet for a simple dowel hole jig. Joining this all together with dowels creates a strong piece of furniture as well as eliminates the need for any fasteners.
To make this bookcase, just download the plans and follow the cutlist. Keep all your grain running the right way and keep track of your pieces and you will have no trouble at all. It really is that simple.
Stained?
Since I was using pine plywood, I thought it might be nice if I stained this project: something I rarely do. Typically I just apply a clear finish and let the natural color of the wood shine through. Unfortunately, I decided to try a product I have never tested: a polyurethane/stain mixture in one can. The results were disastrous. Very difficult to apply, it left ugly streaks and pools of stain. It refused to stick to the birch edge banding.
People use that stuff?
Id like to think I have a fair amount of experience at staining and finishing wood. Ive tried just about every technique there is and I knew this would be similar to applying poly, a fairly time-consuming process. I did everything the manufacturer recommends. I applied a pre-stain wood conditioner and carefully brushed it on using one the the manufacturers brushes intended for their polyurethanes. I let it dry overnight, sanded with steel wool and applied a second coat, which they also recommend. Still looked horrible.
As I was already running behind on this project, I had to make a decision to keep applying more coats (after waiting 8 hours between each) or cut my losses and just paint the bookcase. I opted for the latter. This is a product marketed as an easy one-can finish for inexperienced finishers and DIYers. I cant help but wonder how many of them became as frustrated as me and gave up ever trying to finish wood again.
Yes, paint!
Strangely, I am very happy with the way the paint turned out of this piece! It matches one of the colors in my Jetsons wall clock and fits well in my mid-century modern living room.
If you want a super-easy easy weekend project, make this bookcase with the intention of painting it. If you choose to go that route, you can eliminate the edge banding and just paint the exposed plywood edges. You can also eliminate the dowel jointery and just glue and screw it all together. Recess the screws (or nails) and fill in the holes with paintable wood filler. You can also save money by just using MDF instead of plywood, since grain direction is irrelevant on painted pieces.

Real Wood Beats Plywood But Plywood Beats Pegboard
Well, at least nice birch plywood beats pegboard.
I have two of those metal shelving units (or are they carts?), the ubiquitous chromed ones, that I use for tool storage. The bottom shelves on each unit have pull-out trays, and the top two shelves are, well, shelves. A long time ago I cut pegboard liners for the shelves so the planes and other tools that lived there wouldnt be resting on the metal racks. I cant remember why I used pegboard, but it probably had something to do with having it on hand.
Anyway, it has worked fine, but has never really made me happy. Well, as part of the ongoing "get rid of stuff that doesnt fit/belong in my shop" offensive, I found a solution. I discovered some thin birch plywood that needed to earn its keep or hit the road. Well, Im not a fan of plywood, but it does have its uses and clearly this stuff was more aesthetically pleasing than pegboard, so I made the switch.
Not hard at all, since each fitted piece of pegboard was used as a template for the new liner. Here are some shots of the upgrade.
Before:

After:

Definitely an improvement in my eyes.
The bigger picture:

Its funny how a small change can have a major impact that seems out of proportion. In this case I think the change from pegboard to birch ply improves the whole corner of the shop. Cool!
The tools:

Not much to it really: Japanese style saw for cutting the thin plywood (using a very low angle helps minimize flex and chatter), hand drill for boring the oak lip peg holes (if you spin the drill counter-clockwise for a bit, it will get you started without tearing out the thin birch veneer, then switch to normal clockwise operation), and a rat-tail rasp for creating the clearance notches for the shelving units railings on the back of each shelf. In the background, you can see the old pegboard liner which I used to trace everything onto the plywood. You can also see how handy it is to have your sawbench and shavehorse the same height. This is especially true when working with full sheets of plywood.
The next pegboard to be removed will be the backing on my tool panels, which will be replaced by real wood. I already did the saw panel, which you can read about here and here, but its time to finish the rest.
