What am I doing wrong?

I'm trying to create a tube with a helix 'hollowed out' from it.

I only have the free SU version at home and have subsequently tried intersecting but to no avail.

What am I doing wrong?

Thanks ...

EDIT: the tube and helix are only grouped for ease, I intersected them ungrouped.

I'm guessing while my PC thinks.....

Your geometry needs to be scaled 10x

Lee,

I think it's about time you promoted yourself out of the newbie folder

Haha, it did cross my mind, but then you answered this problem and I realised it's the best place for me.
