A great tip Ted; thanks. I used the handle of our patio broom, banged 2 panel pins into it about 5mm apart, cut the heads off and dropped it down the tube. With one nail either side of the roll pin in the damper, the fork leg in the vise and the head of the broom stopping rotation I got it out no trouble. I have discovered that ancient fork oil smells not unlike sewage too. Onwards to the next challenge.
