Simple Plywood Garage Cabinet
Step-by-step guide made from Indy Farm Life's YouTube video.
This project demonstrates how to build a simple, durable, and economical cabinet from 3/4" plywood. The method is straightforward, using basic tools like a circular saw and a brad nailer, and is intended for utility spaces like a garage or mudroom. The final cabinet is frameless with added shelving for modular storage.
- Difficulty: beginner
- Finished size: 36" H x 32.5" W x 16" D
Safety
- Always wear safety glasses and a dust mask when cutting plywood to protect from airborne particles.
- Use caution when operating power saws. Ensure the workpiece is securely supported before making any cuts.
Must know before you build
- Use an 8-foot track saw guide with your circular saw for accurate, straight plywood cuts.
- Label every plywood piece immediately after cutting to prevent assembly confusion.
- Wipe all excess wood glue immediately; dried glue ruins paint finish and is hard to sand.
- Apply wood filler to exposed plywood edges before priming for a smooth, professional paint finish.
- 3/4-inch sanded plywood ensures an extremely durable, heavy-duty cabinet carcass.
- Incorporate hardwood scraps as cleats for superior, durable support of removable shelves.
Tools
- Circular Saw
- Table Saw (optional)
- Track Saw Guide (Straight edge guide, 8 feet long)
- Brad Nailer (Cordless Brad Nailer, DeWalt, 18-gauge)
- Clamps (Bar clamps)
- Tape Measure
- Level (Spirit level) (optional)
Materials
- Plywood (Sanded Plywood, 3/4 in)
- Wood Glue
- Brad Nails (Harbor Freight, 18-gauge)
- Wood Filler (All-purpose wood filler, DAP, Plastic Wood)
- Caulk
- Primer and Paint
- Hardwood scraps (Hardwood)
Step by step
Step 1: Breaking Down Plywood Sheets
Use a track saw jig and a circular saw to make the initial cuts in the 3/4" plywood sheets.
- Set Up the Track Saw Guide. For this initial step you can use a homemade straight-edge guide, with the circular saw as an economical alternative to a commercial track saw (or buy one).
- Measure and Mark the Plywood. Measure and mark the cut line on the large plywood sheet according to your cut list.
- Tip: This cabinet features fully customizable dimensions, allowing you to tailor your cut list to fit your exact space.
- Cut the Plywood. Clamp the saw guide along the marked line and make a long rip cut with the circular saw to break down the sheet.
Step 2: Assembling the Cabinet Carcass
Assemble the main box of the cabinet, joining the sides, back, top, and bottom pieces using wood glue and a brad nailer.
- Join the First Side Panel. Lay the bottom panel flat, apply a generous bead of wood glue along one end and stand the first side panel on it, clamped flush.
- Tip: A wet rag is helpful for quickly wiping away any excess wood glue that squeezes out of the joints.
- Fasten with Brad Nails. With the pieces clamped, use a brad nailer to secure the joint, placing nails every few inches. It's good to use a lot of nails to ensure a strong hold.
- Attach the Second Side and Back. Repeat the glue and nail process to stand the second side panel on the other end of the bottom, then set the back panel between the two sides and nail it in.
- Attach the Top Panel. The top panel is glued and nailed in place, completing the basic cabinet carcass.
Step 3: Installing Shelves
Install a fixed middle shelf and then add cleats made from scrap hardwood to support two additional, removable shelves for modular storage.
- Install the Fixed Middle Shelf. Measure and mark the position for the central shelf. Apply glue to the shelf edges and inside the cabinet, then slide the shelf into place and nail it from the outside, following the guide lines.
- Add Cleats for Removable Shelves. To add more storage flexibility, you can add supports for two more shelves. Cut small cleats from scrap hardwood and nail them to the inside walls, creating ledges for the shelves to rest on.
- Tip: Using scrap hardwood for the cleats provides a durable support for the shelves.
Step 4: Adding the Face Frame and Prepping for Paint
Attache a simple face frame made from 3/4" stock, followed by filling nail holes, caulking seams, and sanding in preparation for priming and painting.
- Attach Vertical Face Frame Pieces. Attache the two vertical strips of 1-inch wide stock to the front edges of the cabinet sides using a brad nailer, ensuring they are flush with the inside of the cabinet.
- Attach Horizontal Face Frame Pieces. Measure, cut, and attache the top, bottom, and middle horizontal pieces of the face frame, scribing them for a tight fit.
- Fill Nail Holes and Seams. Use wood filler to cover all the brad nail holes on the face frame and any gaps in the plywood edges to prepare for a smooth paint finish.
- Caulk Interior Joints. The next step is to caulk all the interior corners and joints to create a seamless look before priming and painting (This build doesn't cover these steps).
