East Anglian Tourer ( Black Shuck )

If you havn't put the star nut into the fork then you will not be able to tighten up the headset sufficiently for it not to wobble. As long as you have the top of the steerer below the top of the stem/ top spacer the headset cap will grip the star nut and compress the stem, spacers and headset. If there is steerer protruding/just by the stem, the headset will not be able to compress enough. I hope this is clear. Cut the steerer to the right length, put in the star nut and you will be fine.

Yep. I see the error of my ways. Cheers. My previous builds have all been conversions. This is my first build from scratch. A learning curve with, hopefully a happy ending.
