Roof plug 14.

Tide is starting to turn....YAY!!
The side vents caused me serious messing about today....well...the passenger
side vent location did. My template mysteriously vanished...got thrown
a way by mistake...by a friend i suspect...:)
So...spent a while measuring location, and triple checking.

Roof plug 13.

Drivers side section is near enough finished.
Side vent, (Not pictured) needs completing....and everything needs finishing in 220+ .
One of my level checking tools, has highlighted a variation in the passenger side...so, correction needed there...(highlighted in pencil.)
Passenger side is getting there...yay!

Roof plug 12.

Not so much the roof plug, but still relevant to the overall work in progress.
Davesideways highlighted an important idea, a diffuser, and suggested the Lotus design be looked at and maybe copied.
Also, suggested installing front radiator , sticking ribbon, at rear to view air flow, before installing radiator.
When the prototype for first roof was fabricated, we tied string, to boot area, and observed flow into boot. But this new design hasn't had that benefit.
So prehaps a section could be removed from boot floor, a diffuser incorporated, and extra guaranteed flow directed towards rear radiator.
