Attach First Plywood Layer

What happens here

With the internal supports correctly positioned, the creator places one of the plywood sheets directly on top of the arranged lumber. He then uses the Ryobi nail gun to drive nails through the plywood and into the underlying wooden supports. He works across the surface, ensuring the plywood is firmly attached to all points of contact with the frame, creating a stable and rigid first layer for the ramp's riding surface. The sound of the nail gun indicates rapid and secure fastening.

Goal: The first sheet of plywood is placed over the arranged supports and securely fastened using a nail gun to create the initial riding surface.
