This is a Touring of Milan bodied 1949 Ferrari 166MM (sn#0010M). Teardown/restoration was @1996 and has been used on the road (and racetrack) extensively since winning many concours award post restoration.

I'm not going to get into history of this car -- but let's just say that it is fairly significant. Yes -- that is a 125C fuel tank in the car -- common for the very first 166MM's that were built. Many other unique features about this car but this that isn't the point of this thread.

This 166MM was de-skinned to allow for chassis restoration. You literally have to "peel" the skin off on these. Every time you do -- the rolled edges work harden or crack. Conversation of as much of the original aluminum was primary intent -- thus the patches. This 166MM was crashed heavily during racing during it's career -- and even the chassis was still bent from the accident at Pebble Beach in 1950.

Pictures -- I posted my URL and "USE" rules pertaining to. I've had problems with imagines being published without permission; Ferrari authorities selling them to others for $$$; and in general people being idiots. "USE" as posted here at www.allmetalshaping.com is to see how panels are attached, rolled edges, seams, tubular structure, inner fender panels, firewall, attachment of bodywork and what the bare metal chassis looked like when finished (pre-paint). I have 2000+ pictures and this is just a small smattering of them without overwhelming this thread.

wow, car porn

Thanks for posting the pics Mark. It's interesting to see what appears to be accident damage in this one, while of course the obvious areas on the outside look smooth and slick.

If this stuff is not on topic I wonder how folks figure out how to attach panels to their chassis. I feel it is needed and great! No different than members giving me tig welding pointers. It takes a lot of different skills and knowledge to achieve any metal shaping repair well.

As I look at these pictures I'm wondering what the sequence of steps was for the original construction. The panels must have been shaped to fit a buck, and then installed on the tube structure. It doesn't seem like there is enough information in the tube structure to guide the shaping of the panels, it's just for support and to define the edges.

How was the tube structure shaped originally? Was there a "buck" or set of templates that they were bent to? Some sort of fixture that held the tubes in alignment for welding?

Mark, thank you so much for posting these photos. They are an invaluable resource for anyone wanting to understand this technique.

Tubes are usually shaped by hand or knee -- or sometimes with machines to bend. No master templates. No "buck" for bodywork or templates either. No fixtures. You are thinking about how things are built today -- not 100% applicable to how they did it then. The craftsman in the carrozzeria who built this stuff did it daily and had literally decades of experience. Most of it is by hand without measurements even -- just by eye.

None of the cars from the early coachbuilders is identical except for probably wheelbase and a few general measurements ala width / height and basic locations of openings. Each was handbuilt and if you look at the series of cars -- you inevitably see design changes they have learned as they went along -- or whom built it that day within the shop (or how much vino they drank at lunch).

I'll post some Touring/Milan construction photos tonight from the early 1950's to show more "in progress" builds.
