Hi there, so I was wondering about piecing together my dream bike without a custom frame involved, and I have a compatibility question.
The part that confuses me is what kind of fork and frame will work the quill stems? I've seen some pictures of the Kilo TT with what I think is a quill stem, but how about a track fork with less rake that would be compatible with something like a Nitto Technomic? Am I being dumb right now, or is it actually confusing to figure out what parts are compatible with what?

A quill stem traditionally goes into a threaded fork. Lots of threaded forks to choose from, also lots of quill stems. Doesn't matter how much rake the fork has or its fork offset angle.
Please don't use a Technomic on a track bike. The Technomic is a very tall stem and would look out of place on a track bike. Pics of your bike would end up on "that" thread.

Heheh I see, well I can't tell how much goes inside the tube but it does look pretty long. Whatever the case, the shape was all I was after, ideally.
So any threaded fork, but how can I tell what sort of frame will fit a fork? I see something like 1 inch or 1 1/8 inch listed only sometimes, do you think threaded forks are all the same size? And do the frames have a measurement for the size of the head tube or whatever the fork goes into?

quill = 1" threaded forks
for headset purpose also, i dunno if the french are similar (or the italians)

You've got a frame, so get a fork that is made for the size wheels you plan to use; most likely 700c. Forks also have the steerer tube threaded section sized for bikes. So if you've got a 54cm frame you'll need to get a fork sized for 54cm frame. The fork's steerer tube will be long because it's uncut. You install the fork, figure out where you want the stem height to be, then cut the fork tube accordingly. You can do this with a hacksaw but you risk messing up the thread at the top. The LBS can cut it for you or they can clean the threads up with a die tool. Better to leave a little more tube than cut it too short. You can always lower the stem a bit. Or cut the tube again later.
Cinelli, 3TTT and some others make nice quill stems. Search eBay for some pantographed ones but they'll cost you.

thanks, easier to choose the parts now!

Just to correct something:
Both quill (meant for threaded systems) as well as threadless stems have both come in 1" and 1 1/8" varieties. I own bikes with all four system/size combinations.
EDIT: There have also been quill stems with ODs different than the 22.2mm standard for 1" threaded systems. I believe they were mostly old French bikes, but I have a crappy Diamondback mountain bike frame that uses the old 21.1 OD stem that BMX bikes used to have.
