To manufacture a skateboard, you will need the following materials:
-A piece of plywood that is at least 7-ply thick and no larger than 8.5 inches wide by 32 inches long
-Grip tape
-Sandpaper
-A utility knife or saw
-Trucks (two) with baseplates and mounting hardware
-Wheels (four) with bearings installed
-Nuts and bolts to attach the trucks to the plywood (1/2 inch long bolts work best)
First, you will need to cut the plywood to size using the utility knife or saw. Then, sand down any rough edges on the plywood. Next, apply grip tape to the top of the plywood in your desired pattern or design. Make sure to smooth out any bubbles in the grip tape. Now it's time to attach the trucks. Place the baseplates on the underside of the plywood where you want them positioned and mark where you will need to drill holes for attaching them. Drill pilot holes through both the baseplate and plywood, then use nuts and bolts to secure them in place. Once both trucks are attached, it's time to add wheels! Bearings should already be installed in each wheel - if not, do that now. Position each wheel on a truck axle, then use speed washers and axle nuts to tighten everything in place. And that's it - your skateboard is ready to ride!
