Mucho Thanks to Balidey - one phone call, where he spent most of it rightly laughing at my (lack of) knowledge  and a few pointers has got me on the
track...
There are a few things that I couldn't still figure out.
1. I couldn't fillet the top to make the side profile more rounded and pleasing to look at
2. I don't know how to mke the transition from the cone (in middle of part) to the upper part more attractive
Actually - I have thought of a simple way - make the upper bit the right size to start with 
Thanks again to all, especially Balidey...

No problem. Good to hear about the project.
To add a fillet on top is awkward as its a turned item. So SW will struggle to put it on the model as its a point not an edge.
One way is to do a cut through the side. I often have to do this little 'cheat'. Only did one side to show you, and cut through all in
both directions.
To do this shape I draw the two lines first then draw an arc and mate it tangentially, that way its smooth to the edges.

Oooooh I see - one of those! When you said strut brace I thought you meant, well, a strut brace   . Yeah I hear those are useful tubes - though I
thought more to help prevent the role bar folding up in an accident rather than adding anything to the stiffness of the chassis, certainly torsional
stiffness anyway. So there's really no way you can weld suitable bosses/clevises to the chassis and just make a bar with rose joints at the
ends?
One other thought that just occured to me - if you do have an accident, and that tube does take a big load, and being CF splinters into nice sharp
shards, you might not want to be sitting so close to it!

This car is going to end up costing between £85k and £100k. If I have a big accident in it on it's two shakedown trackdays at Oulton, before
I've given it to the owner, then the least of my worries will be CF splinters..........
I've got 2 in my right palm at the moment and can't be arsed getting them out
Here's my second attempt...

Nice - but the prettier it looks the less likely your machining buddies are going to want to make it for free .
Hmmm - I was thinking more like biiig CF broken tube-ends going through your brain, but maybe I'm being a little melodramatic now. Ah well - as
long as you drive safely on the shakedown days, never mind the owner!
Out of interest, what is the monster 550-600BHP motor going into it?

I know what you mean re the machining cost/favour!
I'm not 100% convinced that the favours we've done for him/them are equal, but the worst he cab do is say no!
The CF would never shatter In that manner near me, so I think you may be reading a little too deep on this one!
The engine Is being built still although it should have been completed end of Nov. 
It will be the RS Performance V6 (same guy as caterham levante V8). This will be a 2.3l V6 with a supercharger, weigh about 90 kilos and as above be
about 550-600 bhp. The box is a Sadev 6 speed sequential and I've ordered the geartronics paddle change...
Search YouTube for RS v6 and RS levante if you want a taster, theres a vid of the v6 on a dyno and one with It in his own exige type car...

Sorry Liam, I called it that In my OP as I actually thought they are called petty strut braces... my bad!
I used to call the first one I fitted a "forward diagonal" but was corrected and told it was called a "petty strut brace"...
Ah well, live and learn...
