YST 541 Headset Bearing Removal
For reasons which quickly become apparent when you see the pic below, I'm in the process of stripping the components off my head tube (if not perhaps the entire bike).
I've got everything removed up top except for the bearing itself. I've tried grabbing the race with channel locks, but it doesn't want to move - I'm guessing it's only gotten more deeply wedged into the tube as it's split.
Any advise on getting this thing out without destroying it?
Here's the tool for the job: http://www.parktool.com/product/head-cup-remover
You seem like a DIYer though; I've seen folks make their own by cutting slits into a length of copper pipe and flaring out the ends.
I'm a DIYer with a garage full of tools! So the idea here is that it gets knocked out from the inside-out then? I haven't even really removed the fork, although it's not held in place with anything - just sorta floating inside the tube. I may have something that will do the job - if not, what's another tool!?

Okay, thanks for the clarification. I think I've got some 1" copper pipe in the garage, so I may have to make that tool after all.
As an expedient in the absence of the correct tool, headset cups can be removed using a long punch (preferably brass, not steel) and a hammer. Remove the fork and use the punch around the interior edges of the cups to drive them out. Work the punch evenly around the circumference to drive the cups out straight.
Depending on how forceful you were with the Channel Locks, you may be in the market for a new headset too.
