We’ve finished the main windows in the sunroom – all but the two that will have bookcases that will wrap around on all sides. I’ve been putting off building these because? All together now – I have no plan. Just like everything else it’s just freestyle design, so let’s start cutting some wood and see what happens.
I built 2X4 bases for each side and cut the outside pieces of the bookcase carcass. I used 3/4″ Maple faced plywood for the boxes. This is B-2 grade – a lesser quality than true cabinet plywood – this has a micro-thin layer of maple – but they will be painted and cost the same as birch faced plywood so I went with these at 50.00 per sheet – cabinet grade is about 80.00 per sheet in my area. It takes 5 sheets for this project.
A little more about routing jigs. The best work table for me has always been a single sheet of plywood. You can screw your jigs and stops right to the sheet to make things go quickly and get repeatable results. Above you see the setup for routing bookcase sides. The cross piece is the straightedge for the router base to ride against. The right piece of wood is at a 90 degree angle to the straightedge. The left piece is spaced with a slight gap so that the piece to be routed can slide easily into the jig. It is attached with a single screw into the plywood table to make a pivot. Slide the piece in and clamp against the right hand wood – you have a 90 degree straightedge.
To repeat the routed joints on all bookcase sides you can set the first one and then screw a stop onto the plywood. Now you can repeat this on each piece so that you have perfectly aligned shelves and dividers.
And here’s what that thing is for. The problem is that this area also has to have a cold air return and a cabinet for a TV lift. The duct work for the HVAC had to be out from the wall. The return air will be routed up behind the cabinet and the intakes will be on the top of the central cabinet. Complicated, no? Yes.
The window bookcases are now built as individual boxes, but not fastened together yet. You can see the shelves are aligned with the window mullions to keep the visual plane unbroken. Another anal detail from yours truly.
Now the cases are taken down and painting interiors begin. I would usually pre-paint the sheet of plywood before fabricating, but the routed joint is so tight that just the paint thickness would cause problems in joining the pieces together. Also, some of the plywood sheets varied in thickness, so some of the routed joints were too tight and had to be slightly widened.
Hang in there – we’ll get some books on these shelves eventually.
