Surely they wouldn't have had access to a press large enough to do it in a few stamps like they do these days? Im pretty sure, from what I've seen of other chassis (and what Pur Sang do), that they would have used a lot of heat and a lot of guys with big hammers. Thats just way too hard work for one person though! 9 hours ago, CUL8R said: My hat is off to your dad How thick is that plate for the chassis? 2.5-3mm?

Its going to take quite a bit of squashing on the sides to get it finished before we can see if thats a problem. 1 Quote Link to comment Share on other sites More sharing options...

Must be a heavy sucker Yeah it does. The modern ones are wasted away. Technically its statically balanced without 'counter weighting' but I have no idea about dynamic balancing. These lived a lot longer than the 59 cranks which were a different firing order. T57 is 2-4-2 dynamically balanced where as the T59 was 4-4. 2 Quote Link to comment Share on other sites More sharing options...

Bugatti Bulletin Editor Posted March 18, 2021 Share Posted March 18, 2021 Hi Peter; Your project was brought to my notice by a fellow member of Bugatti Club Australia, where I'm Editor of the Bugatti Bulletin, a twice-yearly journal which is distributed world-wide, having been published since 1960s. It's one of the most highly-regarded single-marque historical car journals around, and actively seeks to capture NZ Bugatti activity as well as whatever happens in Australia. Fair to say, I'm pretty-much gob-smacked by what you've been doing, and I've spent hours looking through your posts, and those of the many followers who have been tracking and responding to your project. I would love to devote a significant section of our next edition to coverage of your project and the processes you have been pushing through, and I was wondering (a) if this would be agreeable to you, and (b) if you'd be prepared to co-operate with an interview for the Bugatti Bulletin? The latter need not be a "live" interview necessarily, as I could send through a list of questions for you to respond to... I understand that you are in a high-pressure professional situation, and that you'd prefer to be working on your T59 project rather than waiting for a bloody phone call from some dick in Australia... So, yeah, please let me know if you would like to proceed with the above, in some form. I respect that you've been doing this on the down-low, somewhat, but I figure that if the wider Bugatti community gets wind of this extraordinary project, you may find a lot of support that you had not previously anticipated. And if it takes a Village to raise a child, it takes a Community of Artisans to create a Bugatti! Kudos to you and your immense talent. Cheers, Michael Anderson (editor@bugatticlubaustralia.com.au) 9 Quote Link to comment Share on other sites More sharing options...

Thats just way too hard work for one person though! Its 4mm! Bugatti chassis-rails were produced by a couple of different manufacturers, and stamped-out by giant presses in the big steel-works operating in France/Germany in the interWar era. Because of the excessive overall length of the un-worked longeron pattern piece, each was arrayed diagonally across the width of the steel sheets that the patterns were stamped from. This had an additional benefit, in that the side-to-side "grain" of the sheet steel was, for each longeron, cut "on the bias" (in dress-maker's terms) which meant that it was much more agreeable to the 90 degree folding along its edges, without cracking and failure. Ettore Bugatti was a bit of tight-arse, and he wasn't so fussed about who made his chassis-rails, or what they were made from, so long as he could get a bunch of them made for a good price. As a result, there are interesting variations in the thicknesses and composition of steel detected in authentic Bugatti chassis-rails arising from different periods and models and suppliers, through the 1920s and 30s. It is useful to note, however, that none of it involved blokes bashing away with big hammers. This was, after all, the era of Krups, and BIG engineering! 11 1 Quote Link to comment Share on other sites More sharing options...

flyingbrick Posted April 1, 2021 Share Posted April 1, 2021 Do you have to worry about your components looking too perfect compared to the originals? 1 Quote Link to comment Share on other sites More sharing options...

Yeah it’s a good point. For me I don’t really care at the moment. For someone replacing an original part they probably would want it to match the engine better. It would be hard to replicate the porosity and dross they have in there so I havnt looked into that. I have looked into aging the Ali though. Can boil in oil, cook in a charcoal dirty fire, acid wash and some other tricks. Will give it a go one day. 2 Quote Link to comment Share on other sites More sharing options...
FraserNZ Posted April 3, 2021 Share Posted April 3, 2021 I honestly don't know whether you are a genius or just plain barking mad!

I started this blog on there but they had issues at some point and it got deleted. 1 Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted April 5, 2021 Share Posted April 5, 2021 Any imperfection in the sand is only going to make it look more authentic! bloody amazing, so now you have to transport it carefully to the foundry? Quote Link to comment Share on other sites More sharing options...

Now I need to drill riser and vent holes in it. Make the big inner core, big runner system and 2 small cores. Fit it all together. Decide if im going to bolt it all together or not. Im concerned its not going to get enough pressure in the top of the pattern where the thin fins are. So im going to add some extra bits which is going to take some mucking around. Then see if the El Camino can carry it (pretty sure it cant!) Quote Link to comment Share on other sites More sharing options...
anglia4 Posted April 21, 2021 Share Posted April 21, 2021 This is my favourite internet project of all time. Love your work. Will you repair that or have another go? Seems a huge amount of work to be doing again... or can you reuse the cores etc? 2 Quote Link to comment Share on other sites More sharing options...

But doing it in the garage is really limiting and makes it a lot harder than it needs to be. I need to figure out a better way. The best way would be to re design the patterns so that the foundry could easily handle them. Then I take them there and do it all. At the moment they are not very user friendly. I think I will weld this one up and make it usable because really all its doing is holding oil. I can re use the patterns to make new cores/moulds (on the patterns that I didnt break!). The cores are the inner bits and the moulds are the outer bits, they are made from sand and are only a one time use. 2 1 Quote Link to comment Share on other sites More sharing options...
