My Christmas 2010 project is to make some built-in bookcases for our “library”. Before cutting some expensive wood I decided to buy two 8×4 sheets of inexpensive plywood from Home Depot (total cost $50) and build a prototype.
The purpose of the prototype was to validate that we got the proportions correct and try out using pocket hole joinery for the case construction. The bottom cabinets are 30″ tall by 18 1/4″ deep. The cabinets will span the entire width of the wall. The wall has a breakfront outline and we shall mirror this with the cabinet layout.

The photo above shows prototype cabinet in (almost) it’s final location. For the finished bookcase I will remove the fake wall trim and this will allow the base cabinets to be pushed flush against the wall. The cabinets have a 1 1/2″ face frame applied to them – I now need to make 9 drawers to fill the empty spaces.
The finished base cabinets will have a 1 1/2″ beaded face frame and the drawers will be inset into the face frame rather than overlayed. Inset drawers are much harder to make, but the end result looks so much better. There will be a 5 1/4″ base moulding wrapping the bottom of the cabinets.
The finished cabinets and bookcases will be made out of 3/4″ Mahogany plywood with a solid wood Mahogany face frame applied.
Lessons learned from the protoype.
1. Pocket hole joinery construction is very quick and incredibly strong. Everything was connected using pocket holes, the cabinet sides, the face frame rails and stiles and the face frame was attached to the cabinet using pocket holes too.
2. It took my two hours to make the small cabinet – that was from a blank sheet of plywood to the cabinet you see in the photo above.
3. I think I’m going to use pocket hole joinery on the drawers too – at least the smaller ones not used as filing cabinets.
4. Very little of the bottom cabinet material will be visible so I won’t bother using expensive Mahogany plywood where it can’t be seen, this should make a significant cost saving.
