The suggested extraction method is to use a flat screw driver but the spoke is too ''engaged'' into the nipple and preventing me to use the flat screwdriver. Is there a special tool for this? Do I have to cut the spoke?
Take a flat screwdriver with a blade that fits the spoke nipples well (width of blade and thickness of blade). Use a dremel tool with a cutting disc to cut a slot in the middle of the blade so the blade can fit on the slot on the spoke nipple over the protruding end of the spoke. Place a drop of a penetrating lubricant on the threads at the protruding end of the spoke, and another at both the broken part, and the other end of the spoke to aid in unscrewing the broken nipple.
Unscrew the broken spoke nipple.
