Thanks, i do like the CAD drawinfs but the ones by hand are simply amazing. How like must they have taken.
I have always loved this stuff, must be a bloke thing.
One thing that has always bugged me and is especially noticeable in the second ferrari image is why are valve stems so long and cyclinder heads so bulky?
Seeme ridiculous to me, think how much more compact motors would be.
Chunko'.
Back on topic.
Anyone know how these cut-aways were done pre computer and CAD?
They can't all be tracings of enlarged photograph's of actual cut-away parts surely?
I can accept that a great artist could re-produce what he sees free hand but would they get the knowledge of the inner workings correct.
