Newbie repairman here.

I am trying to remove the DEATH FORK on my Viscount but can't get the expander wedge to let loose. Here is a page from the book I am following.



I have loosened the expander bolt 3 turns. I have whacked the top of the bolt with a hammer and piece of wood many times. I have tried twisting and lifting the handlebars while holding the bike down. No dice.

Is there some trick to this?
