Stack height + HT + stem < steerer tube length?

I've put together several bikes myself, but never with an old fork. Now I've got this used Judy that has about 17.5 cm of steer tube left, so it's going to be close. I need to make sure that the (cheap) frame and headset I get will accomodate it. I'm basically throwing a bunch of old parts together for a bike that my wife will (probably seldom) ride.

So here's my question: Is the stack height of the headset the amount of steerer tube length it uses up in addition to the headtube length? For example one frame I'm looking at has a 12 cm headtube. If the stack height of the headset is 3.0 cm, does this mean that my 17.5 steer tube will be left with only 2.5 cm left for the stem?

Thanks in advance.

Yep, that math's right...and 3cm stack height's pretty good, too.

What he said... you probably already know it but just to clarify... your steerer tube edge must be 3mm below the top spacer or stem to allow loading the bearings of the headset.

Got it. Thanks to both of you. Looks like I'm gonna get the Access frame, which has a storter HT than the Sette frame in the 16".
