Is it just the wedge itself stuck?
soaking, threading in an old bolt and knocking from underneath sounds just the ticket
indeed, just the wedge - i have removed the stem, and forks from the frame... i'm guessing it needs to come out the way it went in, so planning to soak, and bash from the bottom (ooorrr errr missus !)
using the stem bolt sccrewed in the wedge from the underside, unless i can find a long piece of metal which is a similar width to the wedge?
you get me?
