It has been reported several times about all the curved, nonparallel and otherwise special lines of the Coupé. They have been rebuilt as precise as possible but especially at the rockers they will not be noticed at first sight. But the sill is important. At least it is one of the panels I look at first, when I want to judge how body work was executed. Almost all rebuilt Coupés have more or less awfully made sills.
I have decided to make a prototype first, in order to see how it comes out.
As posted before there is a fragment of an unmolested rocker panel and there are some sketches. First the existing part has been copied onto a piece of paper. Then the curved lines have been interpolated towards front and rear of the part. Next the sketches for front and rear end have been incorporated in the drawing. Four sections have been defined: 1. lower flange, 2. bottom of the sill (the part that will be parallel to the ground) 3. the side and 4. the upper flange.
After completion, the drawing only showed one straight line, that is the bend of the lower flange. The bottom (2) has a straight corner to the lower flange but varies(?) towards the side (3) at the rear it is narrow then becomes wider towards the front end and gets a bit narrower again on the last 30-40 cms. It is obvious that you cannot produce the bend on a brake. The side has a crown added to the basic horizontal curve the body has.
Work plan: 1. transfer the drawn shape to the sheet, no matter how odd it appears to be, 2. cut as precise as possible, 3. Bend the lower flange on the brake in order to give the panel some stiffness, it is 1,9m long. 4. Wheel the crown of the side, 5. Bend the edge between bottom and side on the bead roller, 6. Rectify where necessary, 7. Bend the upper flange on the bead roller, 8. Be frustrated, 9. Throw it in the bin, 10. Have a beer
For the moment, I left out steps 7 to 9, directly went to step 10 because up to now there no reason to throw it away.
PS: pic 5, fixed with magnets only, just to check if it fits
