There are people who have welded frames, but these are considered inferior. So frame longerons should be formed over a mould, to obtain an exact shape. |

Yes, that is basicly what it looks like. Or use a (huge) press. |

That is a foto from the argentine workshops beating a chassis frame over a strong former. |

Someone who is very much in the know told me that when Hugh Conway put this tracing in his Grand Prix Bugatti book, he deliberatley made some of the radius different over the rear axle, to stop making it easy to copy.... All the info you need is shown at the front end, however. Greg |

All the info you need is shown at the front end, however. Greg Well Greg, this may be true or not. I am afraid we can´t ask HGC anymore. Fact is however, that many Molsheim factory drawings contain errors and/or have never been updated with the modifications that have evolved in the production. He who thinks that he only needs a copy of a works drawing to replicate a spare part is doomed. One always needs the original (!) or in the best case several originals of the component to verify. Knowing this, we can understand why many people in the past have tried to reproduce parts but failed. |

Marek - though "inferior" I have successfully fabricated a frame from that drawing....even solved the conflicting radius issue in the back. E-mail me and I can tell you what I know about it..... Attachment: 101_0939-w640-h480.jpg [ 359.58 KiB | Viewed 49446 times ] |

some of the fotos are not real , propaganda . Hugh Conway made deliberatley some of the radius different over the rear axle, to stop making it easy to copy ! This is just a story . He did not use CAD , and was not able to do it better . Today with CAD , I make the radiuses with plus-minus 0,001mm . |
