Threadless Riser stuck on steering tube
Looks like this
I pulled the bolt that is deep inside it. It is still stuck fast with all of the pinch bolts off. I'm assuming that there is a wedge underneath it and all it needs is a good wack with a hammer but don't want to damage anything.

No, the long bolt just engages the star nut in the steerer tube,
to tweak the headset adjustment.
and the pinch bolts just like those on a threadless stem grip your steerer,
to hold the adjustment.

+1 You also might want to heat the riser with a hair dryer (not a torch, unless you don't care if you ruin it -- cosmetically, at least). A few light taps with a rubber mallet could also help to loosen it. Unless it's been on there a long time and has galvanic corrosion issues, it ought to come off.

Put a stem on it and a wheel in the fork. That will let you work it the old fashioned way - straddle the wheel and hold it between your legs to keep the fork steady while you work the stem riser back and forth and up.

Another possibility is that the steerer tube was a bit long, and when the slack was taken up in the headset, the steerer tube was "forced" into the necked down section of the extension. Hard to tell if this is the problem, or how to deal with it without having in front of us, but if one understands how it all goes together, a well placed blow with a hammer will no doubt fix it.

I put the front wheel in the fork, attached the stem and used the handlebars for leverage. That in addition to the hairdryer (thanks!) did the trick nicely.
Thanks guys.
Thanks guys.

made a dummy wheel the other day for a really corroded fork. took apart a front hub for the axle. drilled a hole in my cheater pipe to slip the axle over. reassemble the axle to 100mm OLD with the pipe in the middle. i called it the wheel saver
