After the rollcage was installed, I glued the dashboard, and the seat. Here, I'm shaping the side impact bars. Notice that the driver side is widened outward, while the passenger side is straight.
The seatbelts are Studio27 seatbelt kit. The early show car didn't have the passenger seat, so I didn't make one. Later the real car added a seat, as seen in the Road&Track feature.
The shifter was made of a combination of styrene rods of two different sizes. The boot is Tamiya epoxy putty.
Moving on to the exterior, here's how I made the stays.
First, I cut out a styrene sheet in the desired shape (top), then I put two extremely small drops of superglue to fix the part on another sheet of plastic (middle). After trimming, filing and sanding, I carefully pried two pieces apart with a hobby knife (bottom). Superglue doesn't melt plastic, so cleaning the glue spots is very easy. This way, you can make a pair of identical parts in a matter of minutes.
Here's a pair of vacuum formed taillight cover. It was painted with Tamiya acrylic clear red. The bottom 1/3 are reflectors, so I applied baremetal from the back side. Since the reflector has some kind of pattern, I cut out a small piece of brass mesh, and pressed it hard on the baremetal. It's unclear in these pictures, but yup, the patterns are there.
I'm sure a lot of people will find the following technique useful: how to make a race-car wing.
Cut out a pair of plastic sheet. Make the bottom piece slightly wider than the top one. Curl them on a side of a spray can or something, and add two smaller pieces of plastic to the bottom face of the top sheet as shown. The top part is the left, and the bottom sheet is the right; both are upside down.
You don't want a wavy wing, so make sure you clamp both the leading and trailing edges when you glue the top and bottom pieces together.
Round the leading edge with a sand paper. Depending on how you make the spar between the top and bottom elements, you can make any type of airfoil you want. The winglets are also made of styrene (the orange piece).
I added a 1.5mm-wide narrow styrene at the trailing edge to represent the Gurney Flap.
Now, the wing is ready to paint. Here, I was test-fitting to determin the angle of the wing.
If you want to make one of those irregular 3d wings (like the one with a raised center section), combine this technique with the one I described in the dashboard making.
Next time is how to make a simple front lip spoiler, stay tuned.
