If you are following our
procedure for making fiberglass door panels for your interior, you have
purchased your supplies, found a workspace, removed and disassembled
your door panels, and thoroughly cleaned them.
The next steps are a little more hands on and involve some
serious sanding, so please be sure to wear your
dust mask, eye protection and gloves.
You now need to create any wooden supports or frames to hold the
addition components, if any, that you are adding.
- On my panels, I decided to delete the "door pull pocket,"
and did so by constructing a flat section where the door pull pocket
was with 1/2" MDF board and screwed it into the door panel plastic.
(see pics below)
After cutting the basic shape in wood, I sanded the MDF to the
shape/contour that I wanted for my fiberglass door panels.
- Building mounts for speakers that you want to install in
your door is very easy and thats what I did, so, below are pictures on
how to make "pods for your door speakers in your fiberglass door panels.
Use the mounting template to mark your cut line on the MDF board. Mark
the inside and outside of the circle. Drill a pilot hole in
the center circle and cut the inner circle out with a jig saw or router
first. Cut the center circle first because if you cut the
outside circle first it will be much harder to hold on to when cutting
the inner circle.
Determine where you want the speakers to be located on the door, making
sure that the door will still close if you put them in a weird
location, or have them extending from the panel real far. If
you want to angle the speakers towards you for better acoustics, use
wooden dowel rods cut at different lengths to properly angle the pods.
After you have the dowel rod cut to the correct length, glue
them to the speaker ring and then glue the assembly to the door panel
in the appropriate location.
- I ended up not using dowel rods and mounted the
speaker ring directly to the door panel with wood glue, or
epoxy, after I cut away the door panel pocket with a Dremel
tool and cut-off wheel. I then made a template with poster
board and replaced the cut out section with with a flat sheet of MDF
board. I glued the board in place with epoxy (see below)
the glue dried, I mounted the speaker rings and rounded the edges of
all of the door panel wood for a better contour before continuing to
the next step. I also removed the upper plastic section of
the panel since this does not need any resin on it. After
removing the upper section I sat it aside for later modifying.
Either by hand or with your electric/pneumatic sander, sand the entire
surface of the door panel with 60 grit sand paper. Since you
are just trying to roughen up the surface I would suggest doing this by
hand and more-or-less scuff the entire area.
- The purpose of this step is to create a "tooth" for any
glue and resin that is being applied to the surface to have something
to hold on to. Neither resin or glue will stick very well to a slick
plastic surface, so roughen it up a good bit!
