Very cool.
Years ago I saw a black 'n' white video of Chevrolet casting up a row (yes a row) of their small block V8 cylinder blocks. It went through all the machining processes, then assembly and final fire-up. I'd love to own a copy of that now.

Sounds very interesting!!! I saw a thing about the Ferrari factory on Sky the other night...

No wonder they are so freaking expensive!!! But its just a bit sad to see that everything is made by CNC machines these days... No skills involved in pressing a button... LOL

(Then again I must respect the people that creates the blueprints for the CNC machines)

What happens, do you think, if you misplace the tooling in their holders, or set the work up wrong, on a half million dollar CNC mill? I'm guessing there's a little skill left in CNC other than the programmers.

Anyone care to share the calculations behind that "simple machining" of the gear?

I always laughed when I was assumed to be a bit thick because I wore overalls... underpaid is a better description. Pure bloody magic that is.

Yes,but its not like you need a scientist to run or set it up(When last did you watch OCC).

Proper hand made stuff use to be done by people with 30years of experience in the field,where has that gone? (Please don't say China!!!)

It was replaced by technology that does it faster, cheaper, and more consistently

Maths mate!!! But its a step higher than + and - ... LOL

Sure is... here's some now.

Tell me again machinists are morons? (Not you degrom - a general comment at anyone assuming tradesmen are stupid)

I mentioned to a guy I was thinking of doing a degree after I finizhed my trade and I got "But you're only a tradesman - are you sure you could handle it?"

After not being put off (I nearly was), I hit Uni doing business, but my first glance at the engineering papers told me I'd comfortably fit into a year 3 class...

... sorry - it's a sore point... I'll back off.

Thats what I am talking about!!!

Put a "real" tradesman behind a big CNC machine and you will end up with master peaces at the end of the production line.

I get the feeling now a day they don't properly train people anymore and some of the beginners start with CNC machines and don't have a clue how the basics behind the screen works.(Thats what you get in a fast paced world where you don't have time to wait 10years for a person to gain the needed skills.(You just pre-order them from another country!!!))

Blinged - 500% agreement from this end.

There was a good article about a "tradesman" Honda used to use rather than all its scientists to feddle with there RC30 engines, in a shed with simple lathe and tools, but he had the experience and the "Eye" to get those motors doing things the boffins couldn't.

That's my dream job - programming those things...
