Crown race puller?
David Damerell
crown races short of buying a crown race puller, which would be rather
tiresome for one headset's worth.

It isn't a puller but rather a pusher and the tool is relatively
inexpensive:

Oops, Park Tools was a bit misleading in that they show you a remover
for frame bearing races when you ask. You probably want a device that
looks more like this:

Actually, if you don't mind the race getting some mild blemishes, you
can beat it off the fork with a flat faced punch (drift pin) by
alternately driving the front and rear part from the underside.

a walmart machete will "pull" the crown race.
heat the race till it smokes
insert machete edge bewteen race and fork seat
tap dull machete edge with wood block
move to opposite race side-repeat
then 90 (why no degrees on the keyboard?) repeat
then opposite then as necessary
then the race will work loose with vice grips after heating -more pull
than turn please to avaoid gaulling

spray/dribble with light lube-pcblaster is recommended but red finish
line unshaken is good
then turn-pull with vice grips.

/ screwdriver / punch as a starting point to work it off. Once it moves a
bit it should come off easily by "rocking" it side to side with your tool of
choice. It shouldn't take a lot of force. Go easy, use patience.

I've had no problem getting the majority of them off using a bearing
splitter plate, a block of wood, and a hammer. Position the splitter
plate below the race, rest the plate on the open jaws of a big vise,
protect the end of the steer tube with a block of wood, and tap on the
wood with a mallet to drive the steerer through the race. As long as
there's an accessible shoulder to grip under the race, it works.

Rubber mallet. "Tap" on the front, then back, to work it off the crown.

Well, now I'm confused. Having looked at these photographs, both of these
devices appear to remove the same thing from the frame. What I've got is
what is left over when a threaded headset has has everything screwed to
the fork unscrewed and the lower half of the lower bearing removed with
the fork.
Sheldon's bicycle glossary suggests I am confused about terminology; that
a "crown race" is what is left behind on the fork (next to the fork crown)
and that what I actually want to remove are the two frame bearing races
which are stuck to opposite ends of the head tube, and so the Park Tool
link depicts what I want. Is that correct?

I think G Daniels has the best idea with his cheap-machete concept.
That, or this is one of those 10-minute jobs that may be worth paying a
shop rate for, at least if you're dealing with something vulnerable like
a carbon fork.

This tool is for removing bearing races from the head tube of the
bicycle:

Well that is what confused me so I listed both tools. Yes the fork
crown race is the head bearing race that is a press fit on the fork
crown at the base of the steertube.

I drift them out with a short length of good-sized copper pipe.

it requires purchase, but may be justified on the basis of low price and
potential resale to someone with a car...
automotive bearing puller - thus:
http://www.etoolcart.com/index.asp?PageAction=VIEWPROD&ProdID=1893
the two holes top & bottom are for threaded studs to exert the "pull"
and which you can buy in the hardware store. used correctly, this will
remove even the most obfuscated crown from a wide shouldered carbon fork
no problem, and no damage to fork surfaces.

With downhill MTB forks the crown is so wide you can't get under the race
with a screwdriver (or machete). I just go to my LBS with fork in hand and
the mechanic pops it off with their expensive VAR puller for free. (I did
ask how much I owed him at first and he laughed at me.)

Thanks to all who replied, and apologies for the confusion over the type
of races.

No apology necessary. You stated it quite clearly, three times.

I guess that whistling sound I heard was your joke going over my head
(which despite being a tall guy, happens a lot).

What he said except a 3/4" or 1" wood chisel (not a good one that you
actually use for wood; a dull one) works great to get the race loose,
then work up with a screwdriver.
As for a $5.00 do-it-yourself slide hammer to fit the new race on, get
a 20" long 1 1/4" dia. shop vac extension. The 1 1/4" end will work
with a 1 1/8" steerer; for a 1" steerer, cut a few inches off the 1"
end so it will fit all the way down to the crown.
