Hi folks,
I'm overhauling my '73 Schwinn World Voyaguer. I've run into a bit of an issue trying to take the headset apart. I removed the lock nut, no problem. Now it seems like the spacer between the lock nut and the cup (other nut) is stuck. I realize there is a little tab on the spacer and it looks like it is in the slot like it should be. But I can't get it off. I tried sliding thin objects underneath such as a razor blade and gently tapping with a sharp chisel underneath, I also sprayed some liquid wrench around the area. I definitely don't want to do any damage so any insight would be appreciated, maybe i'm missing something that should be obvious. BTW, I also just disassembled the bottom bracket and had a heck of a time getting that lock nut off as well, though I did get it off. Thanks in advance
