It's probably worth taking your bike in your lbs to get the headset and BB fitted, headsets can be tricky even for experienced mechanics, ask them if they can measure your seat tube diameter and advise you on cranks / chainline. If your intent on doing it yourself you will need a ruler and a set of verniers for a start http://www.tooled-up.com/Product.asp?PID=142730&Referrer=froogle

Is that not down to the shop who put it together for you? I would have thought the BB is not pre-installed in the frame (might be wrong though).
Nope otp's always come with BB's installed. At most you'll get them out of the box have to put brakes and pedals on them and square up the seat/seatpost, stem/bars.
The rpm BB on my surly was pretty shite, lasted less than a year.

Does anyone else imagine when they lock their bike up, next to another sweet ride they're like "holla bro you look sweet today - have you got new tape or something" " yeh cheers mate, how's tricks anyway?" "aww you know same shit, different day", All while your inside the pub chilling with your mates
Well these bikes are like proper brothers, one of them probs live abroad now but they're on holiday yeh, having a rad time, just chillin.
Well anyway thats what I'm imagining - rad bikes, best buds.

It's not copying it, but taking it further ("Have a look at the R20 and R12.5 radius measures in the drawing."). To change this now to a conventional stem version is a breeze (just a diagonal cut-off at the steam instead of horizontal.
CNC steel or EBM titanium, as I do not actually want to start a business with them
You'd be surprised at how much either of these would cost to make. An hour of cnc machine time costs around £50, even if your parts take minutes to make you've got setup time and cutting to figure in. Then you've got programming time on top @ £50 p/h, you've probs got 1/2 an hour to an hours programming there. And then there's finding someone to take on such a small job.
Before you know it you've got a cheap set of drilled forks with a matching paintjob. The only way you'll manage to do this cheaply is to do it yourself an/or adapt something that already exists.
I would love to make all the ideas, even all the designs I come up with. Alas prototyping costs a fortune.

1st ones a copy of the one whats his names friend made without the facility to use a wedge / expander (you still want to fo with a star fangled nut?), i'd be worried about the 2nd idea taking the crown race above the level of the machined shoulder on your fork. Build the crown race into the second idea and you might be onto a winner.
What manufacturing methods are you going to use, what materials are you going to make it from, how many are you going to make, is there a market for this, are forks standard enough for your solutions?
I'd be excited to see prototypes

I built my Colnago for just over £400. Everything was second hand but with practically no wear.
Frame: £211
Mirage Groupset: £76
Wheels Campag Atlanta96 Athena/veloce hubs + Tires: £67
3T Stem: £1
ITM bars: £8
bartape: £10
Chorus seatpost: £17
Saddle: £20
pedals: free
Total: £410This is really nice.
The plan was to do something similar, I spent a good 3 months scouring about for a small frame to no avail, I've also been impatient and bought most of the stuff on my bike new. I like it and does the job though, next purchase some DA cranks.

If you've got a wheel to copy it makes things easier and don't stop until you've got each side laced - running off for a cup of tea or a piddle in the middle of things can fuck things up royally ime.
Let an evening of counting and cursing commence....
