A simple conveyor can turn a chaotic day into a smooth one, and you don’t need a factory to build it. At Gear & Glow we love taking everyday problems and fixing them with a bit of engineering and a lot of elbow grease. Today I’ll walk you through a cheap, sturdy ball‑bearing conveyor that will last years in your home workshop. ## Why a Conveyor Makes Sense Right Now Most hobbyists end up dragging parts from one table to another. That extra walking time adds up, especially when you’re in the middle of a build. A conveyor keeps everything moving in one direction, so you can focus on the next step instead of shuffling stuff around. Plus, watching a belt roll under your tools feels oddly satisfying—like a tiny assembly line in your garage. ## What You’ll Need Before you start, gather these items. All of them are easy to find at a local hardware store or online. - **Two ball‑bearing rollers** – 25 mm diameter works well for most small parts. - **A length of rubber or PVC belt** – about 1 m long, 30 mm wide. - **Aluminum or wood strips** – for the frame. 20 mm thick is sturdy enough. - **Screws, nuts, and washers** – standard M4 or #6‑32 will do. - **A small electric motor** – 12 V DC gear motor, 30 rpm is a good speed. - **Motor mount brackets** – you can make these from scrap metal. - **Power supply** – a 12 V wall wart or a battery pack. - **Basic tools** – drill, screwdriver, saw, and a wrench. If you already have some of these lying around, great! Gear & Glow loves reusing parts. ## Step 1: Build the Frame ### Cut the side rails Measure the distance you want the conveyor to be. I like 800 mm for a bench‑top size. Cut two pieces of aluminum or wood to that length. These will be the top and bottom rails that hold the belt. ### Add the support brackets Cut four short pieces (about 100 mm) to act as vertical supports. Attach them at each end of the rails with screws. Make sure the frame is square—use a carpenter’s square or just check that the corners look right. ### Install the roller mounts Drill two holes in each side rail, spaced about 200 mm apart. These holes will hold the ball‑bearing rollers. Insert a small metal plate or a 3‑D‑printed bracket into each hole, then screw it tight. The brackets should let the rollers spin freely while staying level. ## Step 2: Mount the Ball‑Bearing Rollers Slide each roller into its bracket. The ball bearings inside let the roller turn with very little friction, which is why the belt won’t wear out quickly. Check that the rollers spin freely by hand. If they feel gritty, give them a quick clean with a rag and a little oil. ## Step 3: Fit the Belt Wrap the rubber or PVC belt around the two rollers. Pull it tight enough that it doesn’t slip, but not so tight that the rollers can’t turn. If the belt is a bit loose, you can add a small tensioner: a short piece of wood or metal that presses against the belt between the rollers, held in place with a screw. ## Step 4: Attach the Motor ### Choose the motor spot I like to put the motor on the side of the frame, near one roller. That way the belt can loop around the motor’s small pulley and then onto the roller. ### Make a motor mount Cut a piece of metal or wood to fit the motor’s base. Drill holes that line up with the motor’s mounting holes, then screw the motor onto the mount. Attach the mount to the side rail with a couple of bolts. ### Connect the pulley Fit a small pulley onto the motor shaft. The pulley size determines the belt speed. A 20 mm pulley on a 30 rpm motor gives a gentle 0.5 m/s belt speed—perfect for moving parts without tossing them. ## Step 5: Wire the Power Hook the motor’s wires to the 12 V power supply. If you’re using a wall wart, make sure the plug fits your outlet. For a battery pack, add a switch so you can turn the conveyor on and off easily. Keep all connections tidy with zip ties; loose wires are a safety hazard. ## Step 6: Test and Tweak Turn the power on. The belt should start moving smoothly. Place a few small parts on the belt and watch them glide. If the belt slips, tighten the tensioner a bit. If the rollers wobble, loosen the brackets and re‑align them. ## Tips for Longevity - **Keep it clean** – Dust and metal shavings can grind the bearings. Wipe the rollers and belt weekly. - **Lubricate sparingly** – A drop of light oil on the ball bearings keeps them smooth, but too much oil will attract dirt. - **Check bolts** – Vibration can loosen screws. Tighten them after the first few uses. - **Use a belt made for conveyors** – If you can find a belt labeled “conveyor” it will have a longer life than a generic rubber strip. ## A Little Story from Gear & Glow The first time I tried a DIY conveyor, I used a cheap rubber band and a kitchen timer motor. The belt snapped after a few minutes, and I ended up with a mess of rubber on the floor. That failure taught me two things: you need the right belt material, and a proper motor with enough torque. The second version, built with the parts listed above, has been running non‑stop for over a year. I use it to move printed parts from my 3‑D printer to the post‑processing station. It’s saved me at least an hour a week—time I now spend tinkering with new projects. ## Wrap‑Up A ball‑bearing conveyor doesn’t have to be a big, expensive machine. With a few simple parts and a bit of patience, you can build a sturdy system that will last for years. Gear & Glow is all about taking small ideas and turning them into useful tools for the everyday maker. Give this build a try, and you’ll see how much smoother your workshop can run.
