They are using the same homo sapiens robots as Audi currently do, building the R8!! :)

Separately I will post details of the Mini body shell welding specification as documented on engineering drawings. Those who haven't seen it may be surprised at the attention to detail on the location, number and type of welds used.


That would be most useful, I've got some documentation but a little more detail would be good

Have removed most of the rusty panels now....now to clean up the mechanical bits and start reassembly

No Problem, just replace the panels that are rusted. Make sure the car is supported correctly before removing rusted panels. Also do some measurements and trial fit panels, tack panels in place before final welding. Use an inverter spot welder if possible or you can PLUG MIG. If you have the time and the SKILL give it a go I did a car with similar rust last year.

I don't want to hijack this thread because it's very interesting for the repair issues it's raising, BUT I also would like to ask a question:
"winabbey" made the comment that the mini shell was a very strong "monocoque" unit.
I know it's a bit obsessive but... I've read that most modern car shells are "unitary" - including the mini. "Monocoque is different to "unitary" so I would like to know the technical difference between the two.

According to Wiki:

The aluminum alloy monocoque chassis was first used in the 1962 Lotus 25 Formula 1 race car. Commercial car bodies are almost never monocoques; instead most cars use a method called variously unibody/unitary construction/unitary body/chassis or body frame integral, construction,[10] which uses box sections, bulkheads and tubes providing most of the strength of the vehicle, while the skin adds relatively little strength or stiffness. The term monocoque is frequently misused when referring to unibody cars.[11]

In motor racing, the safety of the driver depends on the car body which must meet stringent regulations and a few cars have been built with monocoque structures.[12][13] McLaren was the first to use carbon-fiber-reinforced polymers to construct the monocoque of the 1981 McLaren MP4/1, and in 1992 the McLaren F1 became the first production car with a carbon-fiber monocoque.

The technical difference is whether the stresses are carried in the skin, or in a supporting structure but the terms are frequently misused. A unitary body has a structural body without a separate supporting frame - but the unitary body normally has an internal supporting structure with relatively unstressed outer panels, whereas a pure monocoque also has a structural body without a supporting frame, but the outer skin forms a primary part of the structure - think of something like an egg, or an aircraft fuselage as a good examples of a monocoque.

Here is a simple clear description of the differences.

If you have any thoughts about which order to replace the panels and supporting structures for each stage, then I'd appreciate the input.

At the moment the rough plan is to tackle it in four stages:-
1. RH inner wing, RH door post/frame, scuttle and closing panels
2. Full Floor including inner and outer sills, heel and toe boards and possibly the crossmember
3. RH rear wheel arch, RH rear quarter skin, RH storage box
4. LH rear wheel arch, LH rear skin, LH storage box

My use of the term monocoque wasn't researched. I simply meant a construction that didn't rely on common chassis rails. Wasn't aware of the term unitary but now I do. :)

off for a swim? why would you dip a unitized body in an alkaline dip. Problems ,just think about how the car was manufactured and sealed. P7676

Now we are back to bare metal, and the list of problems keeps growing. Finding a new shell is looking like the practical way forward at the moment, but I've never been one for practicality and I do fancy a challenge. :-)
