Begin with a perfect hood painted and finished. Add some bracing to allow the mold to be made and then make the borders larger to enable the laying up of the fiberglass material and provide "overhang" to allow for cutting back to size. This piece is a "Buck"
Next step is to create a "shell" of Gel Coat in the exact shape of the part you want to make. In this case, I have placed an air valve to help in the removal of the part from the mold.
Once this shell is made it is reinforced with many layers of mat and cloth to assure consistent shape and to hold the form in place. Then a frame is made to hold the mold stable and allow the work to be done.
Then the new mold is waxed over and over to be sure the part doesn't stick to the mold. This step is required before each part is made. Upon completion of 6 applications of wax and drying time between each application, the gel coat is now applied to the surface of the mold creating the exterior of the part. Then layers of mat and cloth are applied and rolled out to adhere to the gelcoat that is the top of the part to be made.
Above is a final product of he P1800 Hood. It is made of white gel coat with 2 layers of fiberglass mat and 2 layers of fiberglass woven cloth. The result is a weight reduction to 8 lbs from an original exhibit of 30 lbs. This example was constructed for a racing application and is re-enforced from underneath with an "X" rib. Attachment is designed to be with "pins" through the hood and fastened by cotter pins. Other attachments are possible but the original steel hinges and rear clasps are not part of this design.
This is a view of the reinforcement "X" ribs. If application is for a Turbo charger or Supercharger, please advise me as to the conflicts in design and we can provide alternatives.
