Wow!!!
WOW!!!!
Big thank you Mark for your post's what an insight you are giving us all to how some truly amazing cars were built. Please keep posting on this subject because I think you are helping to keep this style of constuction alive . As we all know knowledge is something that can very easily be lost when one or two old time pro's go to glory.

Great pictures, Mark many thanks.
It appears as if much of the tubing simply estabilish the general shape/lines for the panel beaters and does little to support the body proper. This suprises me. I would have guessed that tabs would have been used to attach and/or stabilize the body work such as is seen on the "Gato" picture that Joe submitted. What size and weight tubing is commonly used? If anyone has pictures of applications by different manufacturers, I'd love to see them. Super thread ( pun intended ).

suppleleggera panel attachment fasteners
This is a very timely topic as I've been attaching aluminum inside/underside panels on my chassis and am thinking about building hood, doors, and trunk with suppleggera approach.
I have a question. What's the most common fasteners used with this technique? It seems to me that it should be a blind fastener such as a blind rivet (pop rivet) or sheet metal screw since it's going into a tube. If so, what's the best method of sealing the fastener so moisture doesn't make it's way into the inside of the tubes? For the cars built long ago in Europe with this method, did they seal the fasteners? If not, have the suppleggera chassis tubes held up over time or do they occasionally rot out?

Joel ,
I'm no expert on the subject but talking with a friend (who specialises in classic racing car restoration and race prep) today about this style of construction and he reckons that pretty much everything he has ever worked on has suffered from the dreaded tin worm on both the steel sub structure and the ally skins . Back in the days when these type of cars were made they just didn't have the sealer/paint technologies that we have today.

In the spirit of superleggera, I came across some pictures of a bandini today on another site.
There was a guy in St. Louis when I was a kid that had one of these, he drove it to an outdoor car show for several years in bare aluminum. If I remember correctly it turned up, fully restored, on ebay a few years ago. I always thought these had Fiat engines, but at least this one has a crosley with a Bandini dohc conversion head. This just looks like so much fun... |

here is what frame looks like of Ferrari 250 ml , today this pile of tubing welded together cost 5 million dollars , there is very important part about superlegerra construction and that is chassis have to be very rigid, or you will never be able to open or close the doors
