I'm using the frame of an older touring bike maybe 80's vintage in a new build. Bars, stem and fork gotta go.
I fully removed the stem bolt, but haven't been able to pull the bars and stem out of the fork. The stem can be twisted either direction in the fork, and can be lifted and depressed over a small range, but then stops dead. Like I can lift it out about an inch before it stops budging, push it back in an inch..
I've tried penetrating oil to loosen things up with no luck. I tried hammering the stem out with a rod from the bottom of the steer tube with no give. The old headset is still in place, as the lockrings won't come off with the stem still inserted.
What are my options here? I'm willing to do a destructive removal, I just really need this frame with nothing on it to build up ASAP.
Asking the obvious: did you unscrew the stem bolt a cm or so, then give it a mighty whack with a mallet? If so, sounds like it's welded itself over the years.

ThanksIA fellas,

Hacksaw to the quill of the stem? With the bolt out, and no need to keep the fork, that's probably the easiest route.
Dremel tool to cut the stem just above where it enters the fork, then I was able to remove the headset lockrings, the headset, and finally drop the fork out the bottom.
The steerer is bulging.. probably from the hammering I did. Looks like whatever is holding the stem in there was going to need more than penetrating oil to free up. Too bad I had to destroy the parts but at least I didn't need them for the build that I'm doing now.
The bulge in the steerer means the crown race wont come off like it should. Guess I'ma need to cut it again. Dab, yo!
Buy a new headset! It must deserve one if the stem has been left in for so long without preventive maintenance (remove and regrease at least annually).

Agreed. Both headsets and bottom brackets are too cheap (and irritatingly annoying to replace) to use old, crappy ones in a new build. Same goes for hubs, for that matter. HS, BB, and hubs are the 4 components on a bike that you can only replace after dismantling significant bits of the rest of it, making them the ones where you don't particularly want to skimp.

Are you sure?
Crown races sit on a shoulder; typical steerer tube bulges are not large enough that the race will not fit over the smaller diameter of the (even bulged) tube; and if it indeed will NOT, how are you going to get a new one on?

I was planning to reuse the old BB and HS with new balls, since the cups/cones/races are all in good shape. It's true that neither are particularly big ticket items, but theres no need to throw money at a problem I don't have.
Besides I like wearing parts out (after a good long life of service mind). And I like replacing them. And I've yet to wear out a HS actually now that I think about it.
No I'm not sure. I will have access to a proper race remover tomorrow and will see then. I don't need to worry about getting the new one on because I'm not using the fork again and will probably dispose of it (cause uhh... theres a chunk of stem stuck in it causing it to bulge..)
I want the race off to re-use, even though Zog and Jasper may find this practice unsound. It is my sincere hope that the build is completed by this time tomorrow night.
