All right - look at the length of the tail of the body aft of the rear wheel arch. It's most apparent if you look backwards along in line with
the top of the rear tyre.
I could not understand that no matter what I did with the blend of the rear lower section into the rear panel with the holes I could not get it to
look right.
As far as I can tell from scaling photo's I have to shorten my plug behind the rear arch by about 160 to 170 mm

Ahhh I see it now - the tail section is noticeably shorter now that you mention it.
A bit of cut'n'shut needed then Fred?

So why would the models be wrong?
There wasn't a special body work for some events was there? Not sure about now but endurence race cars ran different bodywork for Le-Mans due
to the sustained high speeds down the strieght, back in the '80s when I used to follow it.

But it's now pretty much done, just a few holes to fill and edges to straighten
Note the foam dust lying like snow on the floor along the wall. I blow it away with an airline, it's easier than sweeping up all the time.

well yes, that's true as well - with CAD though, a mistake means usually tweaking a few spline co-ordinates and examining the difference,
it's the fact Fred's taken the entire back end off again and re-sculpted it - would be heartbreaking having put so much effort in the
first time!

yep pretty much what I do..... but by doing it in the flesh we can also see the change in the flesh.
Also the satisfaction when you have put it right is quite nice.... I almost forget the pain of doing it for the 4th time.
BTW Fred, top job... keep up the good work.

Thanks for the comments guys.
Some more progress to report. I am now happy the rear panel is ready for skinning. All the openings have 1 degree slope returns and the edges are all
radiused.

Moving to the mid section, I have mocked up a windscreen template in hardboard in order to establish the angle of the windscreen recess.

Having reworked the LHS, I am now much happier with the blend into the top of the front wheel arch and the profile of the top of the door. Still have
to finish off and do the RHS.

We have been discussing the merits of CAD verses old fashioned trial and error following the rework I did to shorten the tail. Here we see the other
approach.
Andrew volunteered to do some more work on the nose of the car. This is the refined front view drawing, which was used to generate a tool path to cut
the front 250 mm of the nose on his home made 3 axis CNC router. The part was cut in 3 sections which were glued together.

And today I glued the nose on. I am now looking forward to adding the remaining foam and blending it in once the glue dries.

That 3D router certainly does a nice job Fred - what material is it working with?

Hi Raz.
The material you see there is polyurethane foam, with a density of about 32 kg/m2. That density is not ideal, heavier would be better.

Stunning work there. Lots of effort- and it shows.
The modified door looks spot on to me.
