Discussion
I'm delighted to say that I am still asked for some extra information regarding some of the drawings I prepared all those years (8 or so) ago. So I have been used some new knowledge learned recently to flesh out door hinges.
So below please find two extra, 3 D, drawings of the lower door hinge for an S2, hope they help! I will add the upper hinge tomorrow.

Upper hinge as promised note the lack of a void and the truncated thread length. Also Adrian Venn has reminded me that the lower hinge MUST bottom out on the bobbin and not the fiberglass of the body tub.

Great work Norman, the essence of 'design' by TVR is that the shank of the bolt locks out on the bronze bobbin (the actual bolt length being used does not actually matter, AND, IMHO long is better, as it is an advantage to bring the head of the bolt used away from the actual hinge, so as to stop your hands from being damaged AND getting a socket/spanner on ) the bobbin has 8 threads internally and any new bolt needs to be perhaps 6 threads from the shank, checking that the bolt locks out prior to limiting out on the fibreglass holding the bobbin into either the sill or the upper shell (the bolt will break out of the wing if you allow it to). The threads by themselves will not support the door for very long. A@TVR Door Upper Hinge Assembled Sectioned v1 by nfarmer1, on FlickrDamianS3 said:
Hello Norman
Are you using tinkerCAD or sketchup for those drawings?
Or something not free?
Cheers

Fusion 360 is my software of choice, it would be prohibitive expensive but, bless Autocad, they allow a free licence for education or a hobbyist not working for profit.
It's a fantastic piece of software I only scratch the surface.
Regards Norman
Just to round it off I decided to create a physical representation of the lower hinge, (For the techies I used Fusion 360 for the design work Slic3r PE to slice the STL files and print the components in various shades of colour using PLA and the Prusa Mk2.5 printer.)

It looks as if the physical model has the pivot bolt protruding out of the threaded bobbin. Isn't that hole blind in reality?
I believe there is a void below the bottom hinge but as the pivot bolt HAS to bottom out on the bobbin a quick check to SEE if there is a void is essential.
Knowing TVR build continuity just because there a void on one there's every possibility there isn't on an other!
Hi Norman, There is a void, but the bobbin has the end covered in the fibreglass that is holding it into the shell, it will break through (as the top one will), but unlike the top, breaking the FG you would not create any visible damage just weaken the structural integrity . A@

Yes, that is a really cool 3-d model. It's really helpful to be able to visualise things like this that are normally out of sight.
Do you take commissions? I'd be fascinated to see what you can make of the wide-opening bonnet pivot.
(If I play my cards right, I'm hoping I will eventually end up with a whole car.)

Do you have a detailed and dimensioned drawing? If so I would be happy to try!Do you take commissions? I'd be fascinated to see what you can make of the wide-opening bonnet pivot.

Great work.
How about printing up some front indicator lenses ? I'm sure that the guys on here would like that.
I can send you a SLDPRT file.
Interesting idea send me the file, I'll PM my email and I can give it a go. However I suspect the printing time could stop it becoming viable, but happy to give it a go.How about printing up some front indicator lenses ? I'm sure that the guys on here would like that.
