Fencing it in

The entire shape of the body is aimed towards getting as much clean air over the back of the rear deck to ensure the rear down force can match the fronts. To stop the air falling off the side of the car we needed to create a fence along the side walls. This will add a radius to the top edges hopefully enhancing the looks and add stiffness of the body. We have the lip/fence around the rear tub already and wanted this to blend in, this meant a rather complex section needed to be created that also needed to morph and blend into the the front of the car, whilst also following the £D curve of the top edge. The last thing we wanted to do was create lots of freehand rubbing down, and ultimately not getting a symmetrical or constant shape. Lots of head scratching and we came up with a plan of creating a fixed top edge that we could then follow using a former that matched the rears tub lipped section. Dad tried to use a section of wood, but it simply wouldn't bend in the 3 dimensions and simple angled section also twisted when attempting to bend it in the 2 directions. Dad then found some cable trunking (we had already used the D section when making the mould for the rear under tray on the Fury) in a quadrant section, with the  curved part of the section removed it left an L section on the top edge that would allow the strip to bend in both directions without deforming.


Section fixed to bodywork. You will notice a thin piece of wood that helped create a constant curve that is glued and screwed to the section and bodywork.


With it held in place lots of bridge filler (green) was applied into the section.


After the filler had set, the wood could be removed, the otherside filled and a radius form ran down between the top edge and top surface.


Then using normal body filler, build up ontop of the bridge filler and shaped by running another former down the outer edge.


A light sanding is now required, then more filler applied and formers ran down either side and the shape should be complete.
