Making a homemade longboard skateboard from scratch is a complex process that requires a lot of woodworking skills, tools, and materials. Here is a general step-by-step guide on how to make a wood longboard:

  1. Choose the Wood: Select a high-quality hardwood that is strong, durable, and flexible. Common types of wood used for longboards include maple, birch, bamboo, and walnut.

  2. Cut the Wood: Using a saw, cut the wood into the desired shape and size for the longboard deck. It is recommended to use a jigsaw or band saw to cut the curved shape of the deck.

  3. Shape the Deck: Use a router or sandpaper to shape the deck and create a concave or convex shape that fits your riding style.

  4. Sand the Deck: Use sandpaper to smooth out any rough edges and create a smooth surface for the deck.

  5. Apply the Finish: Apply a finish of your choice, such as tung oil or polyurethane, to protect the wood from moisture and scratches.

  6. Drill Holes: Drill holes for the trucks, which are the metal components that connect the wheels to the deck.

  7. Attach the Trucks: Use bolts and nuts to attach the trucks to the deck.

  8. Add the Wheels: Choose wheels that fit your riding style and attach them to the trucks.

  9. Test the Longboard: Test ride the longboard to ensure that it is stable and comfortable to ride.

It's important to note that this is a general guide, and the specific process may vary depending on the design and materials used. It's recommended to have experience with woodworking and power tools before attempting to make a longboard from scratch.
