Fascinating! Thanks!

You've triggered some memories. I helped Hugh Conway translate some of the drawings in a factory in Slough, "Lawrences" some time around 1980. Lawrence, who had his own Bugatti, (which he'd bent on the ferry at Plymouth) was attempting to cast the twin over head cam engine blocks and most were failing, the valve seat cutters or boring tools would break through and there was pile of failures. We had a sectioned Bugatti block and one of the modern ones trying to work out where it was all going wrong. The quality of the Bugatti casting was astonishing, the end wall was a perfectly straight and uniform 3mm yet the contraction on the casting was closer to 5 mm and non-uniform. We never knew; did Bugatti calculate this or had they perfected it through trial and error? More than once people would arrive in their Bugatti having driven to Slough Trading Estate to discuss parts and get measurements. When I knew Lawrence he was in his 80's (probably, he was coy about his age) and the car was still under the tarpaulins he put on it in the 1950's after the ferry incident, he never did get it fixed.

Thanks just brilliant stuff.

Even though my interests have always been agricultural, your cars and even the Niniette, reflect an era when mechanical rather than fly by wire was the norm, yet achieved so much and share a crossover with the machines I have built over the years.

Thank you on so many fronts you are the world of Bugatti Dutton without your family's involvement i wonder would this great make have survived ?. Tim long may the Dutton company prosper and go forward to even greater achievements D.

Thank you this was informative & very interesting.

A magic world:)

Why is there an extra spark plug in the exhaust on Niniette? Over the years i have only seen three Bugatti up close ,two Belonging to an old mate in New Zealand, almost 50 years ago and one,a type 35 belonging to a young guy who was helping me at a workshop about 7 years ago. His was peices of an original car mixed with Argentine parts and an Anzani four cylinder engine.

Tim, your content is incredible - you obviously have immense, third generation expertise to be able to keep these machines running. Everything you say is so interesting, but you are let down a little by the sound reproduction. It doesn't matter. Neither does it matter than much of the technical details you give can only be understood be engineers. I think I heard the term "longitudinal balls" at some point. I expect all the drivers of Bugattis had those. Even the ones that weren't men. Thanks for such an illuminating presentation. Why so few KZread hits, I wonder? Tom. From France.
