thanks guys for the encouraging words,
some updates, but not too progressive as i'm busy with work recently
the rear lips, first trace the shape from the rear diffuser, then cut out from 0.5mm styrene, i draw line to mark the bending line
clamp it, blow with hairdryer to soften the plastic so i can bend it without breaking the thin styrene
slowly bend it to get the right shape
rough shape
unfortunately 0.5mm is correct thickness but TOO fragile to work with, and i should NOT use thin cement as it weaken the styrene and break it, actually i break it more than 3 times, i think i've to redo in thicker styrene and slowly thin it down
frustrated, i continue other easier parts, the side vent is too shallow if looked from the side, so i add some styrene sheet to make it deeper
reinforce inside, also it's easier for me to position & glue the mesh later
and the rear spoiler is almost done, but i felt the shape is incorrect and too small
the spoiler bracket is made from leftover sprue runner, as i felt the styrene sheet that i had is too soft, first i drill holes, then slowly sand to get the right shape, then i cut it out and slowly sand to get the correct size and fitting, very difficult to get everything glue symmetrically if there's a slight dislocation, as you can see, the position i glue is not centralise and slightly towards the right side.
comments are welcome
