This step by step diy project is about onion box plans. I have designed this onion box so you can store the root vegetables properly and in a stylish manner. For this project you only need 3/4″ plywood and a few strips of wood. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.
When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

How to build an onion box
The first step of the project is to build the sides of the onion box. Mark the cut lines on the 3/4″ plywood sheets and then get the job done with a circular saw. Smooth the edges with sandpaper.
Next, you need to build the back panel from 3/4″ plywood. Mark the cut lines on the plywood sheet and then get the job done with a circular saw. Drill pocket holes along the sides of the panel.
Build the front panel for the onion box. Mark the cut lines and use a saw to get the job done. Drill a starting hole and then use a jigsaw to make the cut out.
Align the edges flush and make sure the corners are square. Insert 1 1/4″ screws to lock the frame of the onion box together tightly.
Fit the 1×1 cleats to the frame of the onion box. Drill pilot holes and insert 1 1/4″ screws to secure the cleats into place. Fit the 3/4″ plywood shelf to the cleats and secure them into place with 1 1/4″ screws.
Drill pocket holes along the sides of the front panel and insert 1 1/4″ screws to lock it to the sides of the onion box. Add glue to the joints and make sure the corners are square.
Fit the 1×2 cleats to the bottom of the onion box. Drill pocket holes along the cleats and then secure them into place with 1 1/4″ screws.
Fit the 1×3 support to the top of the onion box. Center the slats into place and then lock it into place with glue and 1 1/4″ screws.
Build the lid from 3/4″ plywood. Make a 18.5 degree bevel cut to one edge of the lid, as shown in the diagram. Center the lid into place and then lock it with hinges.
Cut the components for the drawer from 3/4″ plywood. Mark the cut lines on the sheets and get the job done with a circular saw.
Drill pocket holes to the components as shown in the diagram. Align the edges flush and make sure the corners are square. Insert 1 1/4″ screws to lock the components together tightly. Drill pilot holes through the bottom and insert 1 1/4″ screws into the frame of the drawer.
Fit the front to the drawer. Center the component to the frame of the drawer and use 1 1/4″ screws to secure it into place tightly.
Fit the drawer into place. You can use hinges to lock it to the frame, in case you want to tilt it.
Otherwise the drawer will slide along the cleats.
Last but not least, you need to take care of the finishing touches. Fill the holes with wood putty and let them harden for a few hours. Smooth the surface with 120-220 grit sandpaper and round the exposed edges with a router. Apply a few coats of paint or stain to protect the lumber from the elements and to enhance the look of the onion box.
