you are almost there and on the right track. spin the spacer to break the corrosion bond. i would sand some more too. i like the emory paper that plumbers use. cloth backed and strong. i should post a pic of the fork holder i made. its an axle from a front hub and a piece of pipe trough it. you can also use the front wheel
