  • The making of a fiberglass hood....

    Phoenix Rising, mentioned in the other thread, (Then and Now), that he had never seen a hood made that way before. So I am going to try to show the preocess step by step, mostly through pictures.....1st through 7th pic is the start of the scoop layout using closed cell foam. The closed cell foam is used becuase you can use resin and bodyfillers right over the top of it, without it melting.
    The next 2 pics in this series are of the final stages of the bodywork on the scoop. I used a sprayable body filler in the last stages because it is somewhat self leveling and sands really easy.
    This was all layed out on my original steel hood, closely following the lines and contours so that the finished product would look like it belonged there and not just set on top.....Now the"Plug" is done and on to the mold making process.

    And now for the mold, all the edges have to be extended and sealed up so that you can lay up the actual hood and be able to get it out of the mold...A final coat of sprayable body filler , then lots of blocking to make sure the plug is straight and free of defects, then on to the laying up of the glass that will actually be the mold....

      Once the plug is where you want it, time for a few coats of tooling gel, the orange stuff you see in the finished mold....

        Then a whole lot of resin and cloth and lumber and stuff to stiffen the actual mold up so that it maintains integrity through repeated uses...

        And then you have a mold.......

                  Neat process, it's always cool to see how this stuff actually gets created.

                      Very, very cool thread.

                      Reminds me of the molds we had for the electric car bodies we used to cast back in high school - I just never got to make the molds, because they had already been made years before I started high school.
