We acquired a massive cabinet from a friend when we lived in Germany. It was circa 1920s and is what I’d call “proto-IKEA,” in that it was designed to be disassembled, presumably because it was so huge and heavy. We grew attached to it over the years, but the problem we faced is that it didn’t fit in our new small home. So this project entailed converting the full size monster into something much smaller by removing the center section and building a new base and top. I had three goals for the build: (1) make a new cabinet using the sides and doors of the old cabinet that could also be easily disassembled; (2) make the new cabinet stronger; (3) only use hand tools. The main challenge: nothing was square in the old cabinet. Each door was a different width, the sides were not square, and the existing wood was warped.
Here’s what the full-sized cabinet looked like in our previous home. It was about seven feet wide.
Here’s the completed “mini cabinet” in our new home:
Here’s a brief-ish overview of the process.
I made the four legs out of some sapele I had on hand. I cut each leg in an L shape to match up with the doors to give it a more seamless look. Then used mortise and tenons to build the frame with cherry.
Here’s the base support, dry fit. I used cherry for the show faces of the project.
For the floor of the cabinet, I used poplar. On each end that would be supporting one of the cabinet walls, I decided to use dovetailed boards for added stability to keep it all together nicely.
For the legs, I used chisels and a saw to slowly shape them out to fit the dovetailed poplar.
Here’s the completed right side of the base.
It ended up having quite complex joinery, but it all worked out. These end pieces of the base frame will support each cabinet side.
Here’s the base dry fit, each poplar board is shiplapped.
The trickiest part of the project was figuring out how to support each wall. The original cabinet has only a single center pin on each side holding the side in place, but these pins were just slotted in and didn’t offer any support. It was basically held together just by the weight of the top. Each side also slots into the base and top with a what is basically a long mortise and tenon. So I had to come up with a plan for the base and top to fit these long “tenons” and also to strengthen how each side attached to the base.
That’s what the following shot shows. The center hole fits the pre-existing pin. Then I added two new holes on each side and inserted a thread in each so I could bolt it in place with a hex wrench. Each side piece also slots into the base.
The top was a much simpler affair. I first cut and shaped the top front.
I went with dovetails for the top frame to keep it all together nicely. I closed up the top with a 1/2 inch plywood insert that is removable so if we need to take it apart again it’ll be easy to move.
This is the completed cabinet showing the interior. The back is 1/2 plywood. The shelf was re-used from the old cabinet and just had to be cut to size. The nice thing about the design is that base, top, sides, doors, and back are all removable, so it can be knocked down if needed to transport easily. I took the rosette from the old cabinet and placed in on the new top (it was just a nailed-on affair, this was not a high-end cabinet). I’m happy with how it turned out.
