Taking apart the BSA forks. These were so gunked and corroded I had to use a stilson to start the undo'ing procedure on the oil seal holders. I tried a method found online with gaffa tape and hose clips, but htat just slid around.
Note the use of a bottom yoke in a workmate to hold the stanction whilst undoing end nut. removing the spring clip is not fun. as is re installing it.
