    Bugatti T57/59 Engine Project

    in Projects and Build Ups

    Posted

    Dads finished up a radiator shell. Looking great.

    The original cores are made from hex flared tube to make a honey comb bundle which is all soldered together. There are about 5000 tubes!

    The plan is to make a false tube core /front but use a custom aluminium multi pass radiator to work as the real radiator.

    It will be nickel plated once the core brackets are figured out and any other tweaks.

    Looking good! I love a nice detailed 3D model.

    Thanks. Doing a proper 'functional' detailed CAD takes a lot of time. I think what I have now will keep me going for a while once I can start making things again!

    LVV cert for what is effectively a stock standard but very old car opens another big can of worms as discussed elsewhere.

    Yeah it’s probably not plane sailing. But I know of at least 2 Bugatti replicas and 1 Alfa replica in NZ that have been through LVV cert. Things like wheels have to be approved by VAC, drive shaft hoops, seat belts, mud guards, no welded steering components.

    Will it be possible to register this car for road use given that it may/will not have any real legal identity?

    If it has 3 original major components (with serial numbers) it can potentially be regarded as a ‘real’ Bugatti. Ie chassis, crankcase, gearbox. But they don’t even have to be from the same car.

    If you’re talking about registering a scratch built car in general then that’s LVV rules.

    Somehow I’ve not previously seen this thread… so I’ve just had the jaw-dropping experience of reading it from end to end :)

    Bloody hell…… no messing!  Thought the block casting was epic… but that sump!! So he goes and makes several:shock:

    This does actually deserve the word AWESOME!

    Thanks appreciate it.

    Awesome, is there any logic to the placement of the speed holes? are they actually dimpled or just hole sawed out?

    Guessing the backing was for weight saving/aerodynamics?

    Seems like they put them everywhere they could except for main mounting points. Like engine, gearbox, bulkhead and braces. Left about ~30-40mm material from the edges and to each hole.

    Not dimpled just straight through.

    The holes save 7kg total. Which is a bit when the whole car had a max weight limit of 750kg.

    The Ali backing to the holes keeps everything closed off. Since thats the cockpit. Aero/keeping junk out

    Just jaw dropping stuff, love this build

    Probably wasn't the done thing back then, but engineering some negative camber into it while you're there wouldn't be such a bad thing imo

    Not that Ive ever driven anything with positive camber but the prewar cars usually had it so that there was no scrub radius. Puts the contact patch right through the king pin to give light steering.

    Did the original chassis have the speed holes (dimples) in it? are you using similar materials or updated to modern specs?

    Yeah they do have speed holes. Backed with an ali sheet.

    Can see them here.

    image.jpeg.ebd653400122413445e641fa504efabc.jpeg

    Original material was a mild steel. Probably low grade (in todays standards and variable. ‘Low background’ pre war stuff so you can’t really buy that.

    So they’re done from G250 mild steel (I think, maybe it was G300). Either way, in theory significantly more consistent and stiffer than the original.

    Bit of an update as requested. See Discussion thread for a 'Life' update.

    My dad finished a second set of chassis rails (gotta both have a car right!) They were actually done close to a year ago now! Time flies!

    I came across some original Bugatti drum brake backings and pads. Not sure if theyll be useful but atleast theyre a cool to have.

    Finished a lot of proper detailed CAD on the front end. Wheels, hubs, axles, springs, hangers.

    The wheels are 8 main pieces, big radial spline onto the rim. They dont look easy to make!:grin:

    Hey, how's this going 

    Yeah good. Had a 'break' for a bit and planning on getting back into the CAD over the winter.

    Updates would be:

    I bought a continuous sand mixer at a government auction for ~$2k. Cost $90k new! Couldnt believe it! Its missing controller and pumps though so thats a significant cost but I should be able to figure something. Foundry guys had a look and said it looks brand new.

    Also got several crucibles in deferent sizes because I plan to make a couple of furnaces.

    The bigger plan is to setup my own small foundry. So ill have a proper industrial sand mixer (since its continuous I can do any mould size) then some furnaces to do my own Aluminium. I would stick with a foundry to do Iron.

    Ive started the move back to NZ. I packed up the whole shed into 4 large custom crates, have them in storage at a friends in LA.

    From July I have been traveling the US in my RV with the family. Plan to do that for another year and then move back to NZ end of 2024.

    So yeah its been on hold for a bit but Im going to go full time on it when im back in NZ.

     

    Ill add some cad screenshots to the main one.

    Chassis update:

    I managed to make it back to NZ for a bit, a couple of months ago, to have a go at this chassis building thing my Dads been raving about! Turns out it is actually hard work!
     
    Hes just finished both rails!:shock:
     
    I just got a bunch of machined parts done. Spring mounts and braces that go between the rails.
     
    Just have two sheetmetal braces to figure out then all of it can be bolted/riveted together (with a few more holes and some tweaking I'm sure!)

    Basically all done. Engine went in a few weeks ago and have been ironing out all the issues. There have been alot!

    Put a fancy Progressive Ignition in to sort a 'dieseling' issue. Now it starts and runs great. Little more accelerator pump work and the trans needs a bit of tuning. 700r4 has a governor with weights/springs to tune shift points.

    It was also so loud I had to put a new exhaust on! Ill get a video at some point.

    Can spin the tires without much issue!:thumbleft:

    Chassis update. :thumbleft:

    My Dads been working away on this in his spare time. Many press tools, dies, hammering and probably injuries later a chassis rail is formed!
     
    Looks like the real deal! Pretty impressive.
     
    The other side should be a lot easier, so he says :)

    This is how you make a 40Ton backyard press to do some final tweaking.

    Decided I should allow some time to have fun with the car before considering Webers. So I got a new Holley Double Pumper. Looks the business.:thumbleft:

    Went with an old 50s Cadillac air cleaner. Not a fan of the normal round ones.

    Did some painting and started assembling things.

    I have another vote. Should I just clean up the rocker covers or go black wrinkle with ali fins?

    Black with ali fins = :blink: Confused

    Raw ali patinaed = :sad: Sad
