I was pleasantly surprised today
as I received the colour sample promised to me by the guy who will be taking
care of the paint-job. Sadly it was already
dark outside so not able to judge it properly for which daylight is essential.
But with some tinkering with the calibration on the computer screen this is what it
should look like. And as you can see it matches rather nicely with the Red
Tartan cloth for the seats and door cards. Will see tomorrow if the paint recipe needs
some adjustment or not ...
And almost as important for that
period early-TR7-70's look is this rather obscure and crude looking piece of
rubber which I too received today ...
It's our first attempt at
fabricating our own fuel filler cap seal for the large early fuel filler cap.
This seal is no longer available and all three my early caps didn't have a
decent seal. This being the best one ...
I first tried various
after-market industrial seals but didn't find anything suitable. So I was already
looking for a nice after-market black alloy aero cap. But a few weeks ago
(probably over some beer) I was discussing this with a good friend and during
this discussion I was reminded by a recent article in PPC-Magazine. In this
article the guys at PPC described how to make your own polybushes etc. So why
not try that approach for the seals? And this is where the original seal came
in handy. With that I could knock out a simple CAD drawing of the seal ...
And with this drawing we were
able to fabricate a simple mould, with shown result. With a little more care
and patience the seals coming from the mould should be of much better quality
and fully up to the job. We just have to determine which compound we have to
use, so the only test remaining for the prototype seal is to see if it is fuel
resistant. To be continued

OK, so I'm 4 years late with this comment, but I didn't see the original post until just now. The original rubber seals for the "big" gas cap actually are still available. I bought several to repair my own car's cap and to have extras for when they inevitably deteriorate. Moss Motors has them, p/n 071-966: https://mossmotors.com/seal-large-gas-cap?assoc=63205
Since I wrote this post I have become aware of this fact.
But we already have a mould to fabricated them. And shipping from the US is probably pretty dear.
