Have a read through, pretty amazing engineering.

I found it pretty funny, that the book about the car costs $4500. Smile

Some interesting labour intensive engineering in there too though.

I'm still trying to work out how an aluminium book cover requires 35lbs worth of material to manufacture...

because you take a hunk of aluminium, then remove bits, to make the bit you want

as with the car

so for example, imagine if a can of beer was made by hollowing out a solid cylinder of aluminium

a 1lb of aluminium may have been used in making it, even if only a fraction of an oz is in the finished product

I'm aware of how the milling process works, colin1. I was merely commenting on the relative inefficiency of it: that's a lot of material to be cast aside. While I know that it'll be recycled, the amount of energy used to recycle it would be very high; ergo, it's a pretty energy-expensive process.
Most of the milling I've done has been only to refine the shape of pre-existing aluminium objects, not doing it from scratch, so I was unaware of just how much material is 'wasted' in the initial cutting.

They made the whole car that way. In the online book, it shows the skips of swarf taken off site. A tonne a week apparently.

I agree its pretty inefficient, but i guess when money is no object, its better to use a solid part carved frome one piece of aluminium.

However, I cant help thinking their method of joining pieces, using dowels and bolts is a bit inefficient. I'd prefer the kind of contact bonding that lotus uses.

But I don't know the pros and cons of each method.

You soon get bored of billets when you have to lump them around all day, so it isn't as cool when you see a finished product. A lot of people would go 'wowowowowow look at that, must of taken ages to make'. Nope, it would of taken about an hour to make Laughing

seen now cheap they are.

base models start from 40 grand.

which isnt exactly bad considering the exchange rate and coolness.


But that doesn't include the stuff you need to make it move Laughing

I didn't see any reference to the bodies actually being made in the former Mig factory in Poland...
