An update I meant to post some time ago...
A more detailed look at how the roadster tail was made, just in case anyone wants to have a go at converting the Revell coupe kit into a drop-top.
The roof section was cut off the main body part to begin with.
It needs chopping at the top of the screen pillars - those will still be needed - and close to the rear of the car, approximately where the boot lid ends.
A cross-brace was glued between the two remaining 'flappy' wing sections at the door end.
Tape the part to the kit floor panel to get the gap correct.
Hold the roof section underneath the rear part and roughly draw in around the hole.
Cut the roof panel to fit.
On the inside of the parts, glue little plastic tabs for the roof panel to attach to and glue the roof in place.
Once dry, lots of filler is needed to fill the gaps and build up the correct shape.
The front of the roadster tail (back of the cockpit) needs shaping with plastic sheet and filler.
I used a Google image plan of the E Type, scaled to the right size to get the shape and position of the boot lid.
This was cut from 60 thou plastic sheet, formed in my hands and double-sided taped to the rear section.
The D/S tape stops it moving about.
Carefully scribe around the lid template umpteen times with a dental probe to get the lid outline scribed into the plastic.
You can now decide whether just to use the parts as-is, with no opening lid, or make a rubber mould and slush-cast it in resin which is what I did...
You will see in the last few pics I actually re-cut the inner tail section with a razor saw and lowered it as I wasn't happy with the overall shape near the cockpit.
I hope this waffle is of use to anyone, and hopefully the pictures make a bit of sense...
