If you post a pic showing the other side of the bodywork sample I should be able tell you exactly what materials it is made from Dimples are not for aero reason but from the Nomex honeycomb core, printing through the very thin outer carbon skin of the carbon sandwich panel construction, outer skin will be 1 ply of carbon and only about 0.15mm thick Weight of the paint alone could be as high as 25% of the total weight of the bodywork, especially as Alpine are using metallic paint which is heavier than a flat colour

1ply carbon outer skin? Paint weight maybe up to 25% of bodywork weight?
Thats incredible and fascinating. To how many decimal places does an F1 constructor track mass properties? |

Later one of the other tour guides asked how in the world we got to go to the floor. The guide said getting into the Oval Office is likely easier than on the floor. Peter Porsche himself gave us the OK.

I'm not right in the head so let my OCD run free on my own designed parts, I track weight to the nearest 0.1g for individual parts and laminated ply pieces. When counting laminate thicknesses I work to 0.001mm for each individual ply  A single laminated part contains 100's or in some cases more than a 1000 individual pieces of carbon, machined inserts and core etc. All the little bits add up to a slightly larger little bit so everything is worth counting I give myself a weight saving target which is on the high side of extremely difficult and the low side of impossible  Quote:

.001mm?
How? That’s got to be something around 5% of the dimensional tolerances I’m used to seeing for carbon fiber cloth. I was going to say 4%, but I rounded it up, just to be charitable. |

To the nearest 0.001mm is the theoretically correct calculated thickness of the pre-impregnated cloth, these thicknesses are usually supplied by our material suppliers There is of course a deviation from this due to the tolerances of the dry fabric, resin % content, resin density, cure pressure, mould expansion, quantity of plies, fibre orientation/drapeability etc etc Most F1 composite components are extremely 3D shaped and relatively complex compared to aerospace parts so every little bit counts. Also I need all the help I can get as I like to push stuff to the extreme As an example to explain the complexity and why I work to the tolerances I do I wrote a detailed description of a part I've done without naming the part but I realised Won might be able to work out what it was so deleted it I'd love to show pictures of the type of parts we do as some of the stuff is way out there but I can't  sorry!

Well, if you tell me that you had a chat with Colin, then we have to have a short discussion.

Thanks Paul, I should share more really as what's shown on Netflix or the press is just the tip of the iceberg
All the action is the engineering, simulation and manufacturing back at the team factories, not glamorous in any way like the track so no one gets to see it on the TVLes, I know Cunucks are clever as half of me is as clever as yourself and Won

One of the greats during an era of giants.
R.I.P., Sir Frank. "The Williams team claimed 114 F1 victories, seven drivers’ titles and nine constructors’ championships."

What a sad day
Can't say I knew Frank but worked at Williams for few years, often visiting the F1 team. Frank was often sat outside the front entrance door catching some rays, always had time for a chat, knew most people by name and a twinkle in his eye for the ladies Every F1 team I've worked for uses the well worn out phrase 'we are family' but for me Williams has been the only team that lived by that mantra When I fell over dead, my Williams 'family' I worked with were the first friends to visit me in hospital, the team sent Mrs Ahab the biggest bunch of flowers she's ever had and treated the two of us to a lovely meal out. When I returned to work the care and concern shown to me was humbling, especially as I was only adopted family and not even a F1 employee  Room has got a bit dusty here so RIP Frank, you Sir are an F1 legend!

The Jeddah street circuit looks nuts. I predict many safety cars.
