no drive to speedo

Hi all
I'd welcome a few suggestions as to what might be the problem here. First off, the car is a new rebuild S4SE, just completed. On my first test drive, everything worked except the speedo. I suspected the angle drive on the gearbox, and sure enough it was pretty rough so I replaced it and the cable. I reassembled it all, it seemed to go together without too much difficulty. Still no speedo. I disconnected the cable from the speedo, and the angle drive from the box and got someone to watch whilst I turned the quill by hand. Sure enough, the cable turned at the speedo end, so the angle drive seems ok. So I reassembled the angle drive to the box, and drove the car up the road - no movement of the cable inner at the speedo end. I'm wondering if it is possible that the quill is not engaging with the driven gear at the gearbox? Is there anything else that could go wrong at this end? I'm a bit stumped, short of jacking up the car and putting it in top gear whilst the engine idles to see if the driven gear is turning! I did notice that the aluminium extension piece the angle drive screws to is a bit loose even though the clamp fork is done up tight. Anyone got any bright ideas, please?!
