Quill stem issues

Paul D said:

Am I being dense, or should a quill stem be held in place simply by
tightening the top bolt (and hence expanding the stem inside the headtube)?

My old Cinelli one expanded the two sides of the stem from inside, my new
Deda one has a bottom section that is pulled upwards on a 45° slant as I
tighten, but I can't get the new one to grip enough to hold the forks.

What am I doing wrong?

Have you lubricated it so the surfaces slide easily over each other to grip?

Make sure the wedge is done up a bit further before inserting the stem.
It may just be spinning without tightening.

Yes.

I'm familiar with both those types, yes.

A quill stem isn't supposed to hold the forks; it should be used in
conjunction with a threaded steerer, and a screw on headset. It's the
headset that holds the forks.

Is it the right size stem for the steerer? I had one on an MTB that was 1"
going into a 1 1/8" steerer, would not tighten.

Yes.

(Inside the forks, which are inside the head tube).

I know what Paul means. The stem has to grip the forks otherwise it won't
turn them and will slide down.

Holding the forks is no good unless you can turn them as well :-).

Try and tighten up the wedge a little more before fitting.
