It doesn't show very well in the photo, but the shelves of the cooler are mostly open screen, to allow for cool air to circulate through the cabinet.
I can't put an exact age on my cooler, but it probably dates back to the 30's when my house was built. Other than the hinges and latches, there are no metal parts or modern cabinet-making components. The shelves are supported across wooden battens which fit into notches cut into vertical rails at each corner. More on this below.
The goal of this project is to produce a pantry cabinet to go alongside the cooler and blend in with the style.
The new cabinet attaches directly to the side of the existing cooler, so was designed without a right side. If you're building a cabinet to go in the corner of your pantry, you can use this design unchanged. If it's going to be free-standing, then you can add the other side easily enough.
The design was done in Sketchup. The Sketchup model is attached.
The work was done partly in my garage, and partly I made it at Techshop.
I've included the cad model for the 8-foot cabinet shown here. I chose an 8-foot by 4-foot cabinet because plywood comes in 4x8 sheets and this way the numbers came out even. Feel free to fire up Sketchup and modify the dimensions of the cabinet to suit your own needs. You can actually increase the height by about three inches and still be able to make the cabinet back out of a single sheet of plywood. (The cabinet shown here is actually closer to 8'8.)
