How to build a dolly cart? Step by Step DIY

Building a basic dolly cart can be an accessible and rewarding DIY project. While there are various types of dolly carts, this guide will provide step-by-step instructions for building a simple flatbed dolly cart. Once you understand the basic construction, you can tailor the design to fit your specific needs.


  • 1 plywood sheet (3/4-inch thick, at least 18×32 inches)
  • 4 swivel caster wheels (preferably with brakes)
  • 16 wood screws (length suitable for the thickness of your plywood and the wheel brackets)
  • Sandpaper (medium grit)
  • Wood finish or paint (optional)
  • Handle or strap (optional, for easier maneuverability)


  • Saw (if you need to cut the plywood)
  • Power drill with a drill bit and screwdriver bit
  • Ruler or tape measure
  • Pencil
  • Safety goggles


  1. Preparation:
    • Make sure your plywood piece is the desired size. If you need to cut it, mark the measurements and saw the piece down to size. For this guide, we’ll assume an 18×32-inch rectangle.
    • Sand down the edges of the plywood to avoid any splinters.
  2. Position the Wheels:
    • Turn the plywood sheet upside down.
    • Place one caster wheel near each corner, ensuring they are evenly spaced and not too close to the edge. Mark the screw holes of each caster with your pencil.
  3. Drill Pilot Holes:
    • Safely put on your safety goggles.
    • Drill a small pilot hole on each of the marks you made for the caster wheels. This will make it easier to screw in the wheels and prevent the wood from splitting.
  4. Attach the Wheels:
    • Align the caster wheels with the pilot holes.
    • Using the wood screws, attach each wheel to the plywood. Ensure the wheels are securely fastened and the swivel function is working smoothly.
  5. Finishing Touches:
    • If desired, apply a finish or paint to the plywood to enhance its appearance and durability. Allow ample drying time based on the manufacturer’s instructions.
    • For easier maneuverability, consider attaching a handle or strap to one end of the dolly. Ensure it’s securely fastened.
  6. Testing:
    • Turn the dolly cart right side up and give it a test. Place a heavy object on the dolly and push it around to see how well it moves.

Safety Tips:

  • Always wear safety goggles when cutting or drilling.
  • Make sure your work area is well-lit and free from obstructions.
  • Choose swivel casters with brakes for added safety, especially if using the dolly cart on inclines.


Building your own dolly cart is not only cost-effective but also allows for customization based on your requirements. Once you’ve mastered the basic design, consider experimenting with different materials, sizes, or added features like shelving or padding. Whether for home or professional use, a DIY dolly cart can prove invaluable for various applications. If you need an industrial grade strength dolly check out the Scoop Dolly by SawTrax.
