Thanks, Argus! (It's not actually a case of 'more turns is always better' because as turns increases, winding self-capacitance also increases so as low-frequency bass response improves, high-frequency response drops off. But this is unlikely to be the limiting factor with the wire Chris has.)

Chris - another thing to get right, is make sure you have a winding mandrel which supports the side cheeks of your bobbin. By the time you have filled the bobbin with wire, the pressure on the side cheeks is pretty high and if unsupported during winding, you are likely to find that they have spread apart so much during winding that you can't fully insert the laminations. And that also kills inductance and hurts low-frequency response!
