http://www.ukbikestore.co.uk/produc...tompress-pf30-road-bottom-bracket-4668mm.html ordered this devistated I've just realised this says 68mm and the venge is 61!!! Can I make this fit??
The bottom bracket should fit, but it is likely that you need spacers between the bottom bracket and the cranks (7mm of spacers it looks like)

I've got spacers for the crank could I just space out the crank instead of the pf30? I'd rather not have to shell out the 18 quid for 2 rings as it will put another two week delay on things,
Honestly, I do not know the answer to that, and calling whoever supplied you with the frame might get a better response

My LBS says its physically possible however it is not something they do or advise. They always advise using the spacers as anything else is problematic

How do the FSA crank attach onto the axel? If it is side loading, then you might need to rethink your washers.
Sram use a bolt in the left hand crank, that as you tighten up, brings the arm into the centre and therefore into position. This create pressure from the crank onto the bearings - except the interface between the two is designed in such a way that this doesn't occur.
Shimano Hollowgram does not have sideways pressure apart from a miniscule amount of preloading from the black dust cap bolt. This removes the play, and then the crank arm clamps onto the axle using the allen key bolts. I think FSA might be the same as shimano, which is good news if you want to use DIY spaces.
If there is sideways pressure, DIY spacers may effectively press on the bearings which could push them out or stop your crank even turning.
Sorry if I have not explained this well - basically a picture of how the left hand crank arm attaches will help.

The crank arm is screwed in with an Allen key when I get the bb ( if I ever do at this rate) I'll attempt some trial end error until I can afford the correct spacers
