If you've ever needed a solid, no-nonsense rack for hauling gear, organizing your workshop, or mounting to the back of a vehicle, you've probably noticed that commercial options can be shockingly expensive. The good news? You can build one yourself using basic half-inch electrical conduit and a few pieces of scrap wood — and the result is strong enough to support serious weight.
This project is straightforward, highly customizable, and costs a fraction of what a store-bought rack would run you. Since the top platform is made from wood, you can easily attach milk crates, bins, or other containers using simple screws. It's the kind of build that makes you wonder why you didn't do it sooner.
Below, we'll walk you through the entire process in five clear steps — from measuring and cutting the conduit to adding the final upright supports. Let's get building.
Measure and Cut the Conduit
Start by taking precise measurements from underneath your intended mounting surface to the point where the rack will terminate — for most setups, something around 24 inches works well. The bottom of the conduit frame should sit level with the ground or mounting base for maximum stability.
Cut two lengths of half-inch conduit to about 24 inches each. A bench vise is your best friend here — use it to hold the conduit steady while you flatten and shape the ends. You'll want to bend the tips slightly inward so they sit flush against the bolts that will secure everything together.
Cut and Prepare the Wood Platform
The wooden top is what gives this rack its versatility. Cut a piece of sturdy lumber to roughly 18 inches by 6 inches — this provides plenty of surface area for mounting accessories while keeping the overall profile manageable.
Sand all the edges until they're smooth and consider applying a coat of paint or sealant if the rack will be exposed to the elements. One of the best features of this design is that you can screw a milk crate, toolbox, or virtually any container directly onto the wood surface with minimal effort.
Drill the Mounting Holes
This step demands patience and precision. Using a drill bit that matches the diameter of your conduit — typically around 3/4 inch — bore holes through the wood platform. The lumber needs to be thick enough to support the conduit securely, so don't skimp on material here.
Drill from each side of the board toward the center so the holes meet in the middle. This technique produces a cleaner result and helps prevent the wood from splitting. Once the holes are drilled, use a small round file or a rat-tail rasp to smooth out the inside edges. A clean hole means a snug, rattle-free fit for the conduit.
Cut the Threaded Rod and Assemble
Finding bolts long enough to span the width of both uprights can be tricky, so here's the workaround: pick up a length of quarter-inch threaded rod and cut it to size. Cap each end with a nut and you've got yourself a custom-length bolt that holds everything together tightly.
Make absolutely sure the rod is long enough to pass through both conduit uprights with enough thread left over on each side for the nuts to grip properly. A little extra length is always better than coming up short — you can always trim it down later.
Add the Upright Supports
The final step is adding the vertical support struts that connect the rear axle area to the threaded rod at the back of the rack. These supports are what keep everything rigid and prevent the platform from wobbling under load.
You'll need to measure carefully here to ensure the rack stays level. A good approach is to attach the rack to its mounting point first, then measure and cut the upright supports to fit. Take your time getting the angles right — a level rack not only looks better but distributes weight more evenly and reduces stress on the mounting hardware.
Pro Tips for a Stronger Build
Use a pipe cutter: A dedicated pipe cutter gives you cleaner, more precise cuts than a hacksaw and reduces the need for filing.
Add rubber grommets: Placing small rubber grommets where the conduit meets the wood helps dampen vibrations and prevents rattling.
Seal everything: A quick coat of rust-resistant spray paint on the conduit and a waterproof sealant on the wood will dramatically extend the life of your rack.
