Sometimes the standard off the shelf tools just do not work right. Over the years I've fabricated quite a few. Playing with the camera this evening and snapped a pic of the tools. They are nothing fancy but do the trick.
25mm (6061) & 12mm (Brass) axle adapters
3/16" Internal nipple driver (Standard deep socket turned down on the lathe clearing the rim)
Lets see pics of other handmade bike tools.
