      Especially if you have a project like this : **LINK**

      Re-work is expensive, and may not convince your customers !

          The politics of these things mean that if any concerns are valid they will be addressed and if these concerns are inflated there will be some early retirements handed out

          France won't want its international engineering status put at risk

            Thanks for the link which is right up my alley at the moment as I have undertaken to give a talk about electricity!

              Poo happens! It's a question of who gets the blame.

              Back in the late 60's my local council of the time built a new set of council offices at a huge cost. They'd got to the second floor when checks revealed that the foundations would be inadequate and the whole thing was knocked down and re-started. A junior was sacked. Who would have thought that a multimillion pound project woudn't have its structural calculations cross-checked? Yeah, likely.

              My last year at college and a mate who had graduated and was working as a surveyor on the new Euston railway station told me he discovered a room the length of the mezzanine and a few feet wide with no doors or windows..

                laughlaugh Fits right in with their international engineering status. Ever worked on a Citreon or Renault?

                Australia just bailed out of its contract with France for its next generation of submarines because the whole thing was a fiasco before it got even got started.

                  I used to say that the only good thing that came out of France, were Michelin Tyres. Have not used them for years now so I am not sure that is true anymore.

                    I was never a fan of French cars and in particular, Citroen.

                    Not long ago and for some reason unknown to me, a suggestion appeared in YouTube about a Citroen DS21.

                    I clicked the link and it reminded me that the French have had better times. wink

                    If I had the money and wanted a classic car, then I think I'd go for something like this:

                      As an apprentice many years ago, I once cut a 6 inch dia hole in the wrong place in the hull in the very bottom of a new ship…..fortunately it was in dry dock at the time….

                      I still have that piece of hull on my table as an over large industrial coaster for my mug of tea, to continually remind me to measure twice cut once !

                      Regards to all

                        I drove past this place every week, watching it gradually get bigger, then one day it seemed to be getting smaller again…it’s almost finished now:

                                        I remember making some repair kits for £2,000,000 + power boats. Design flaw, testing on a lake in Switzerland the boat hit a “bit”of floating wood and ripped the transom out. I think we made 25 of theses repair kits that were fibreglassed into the transom

                                            Oh, I typically measure twice, measure thrice…. still cut it the wrong size!

                                            ' ' '

                                            Hopper –

                                            I own a Renault!

                                            My days of grovelling under cars in the street outside the house are well over, but when the MoT showed as "advisory" it needing a new "cabin air filter" – Renault's own term for it – I assumed it would be a simple enough DIY task. I did though take the precaution of investigating it before buying a new element.

                                            Just as well, for I have never found where it's hidden! Any and every cover I unclipped revealed anything but a filter – masses of electrical stuff mainly.

                                            Yoo-Toob did show it is a fairly large unit so hard to lose, and a simple task once you've unearthed it, but on all models of Renault Kangoo except mine; Haynes seems never to have published a manual for them.

                                            I left it to the next service and MoT and let the garage deal with it.

                                            ' '

                                            I do hope whoever completed that Euston Station room was on the correct side of its wall…..

                                                      Thankyou Circlip. I did wonder that, as being somewhere logical, but couldn't find any of the heater assembly either!

                                                      Each of the videos I had found showed a different variant of the car.

                                                      Renault did come up with the goods though when I needed to re-set the radio's code after I had replaced the battery. The process is not described in the Owner's Handbook, though a previous owner had written the code in it. The battery had finally expired in The First Lockdown…. two years ago. It'd had not done badly though. All its labels were in French so I think it was the original one from new.
