Sometimes you have to modify a tool-
a set of Lyotards I did just recently needed a home made dust cap wrench ( Campy was close but not) and a ground down socket to engage the cone with confidence.
don’t overpack with grease- a “25%” fill is plenty and tweezers to place the bearings
a vice or vice grip with protection can be your third hand.
some planning required, a clean dead flannel nightgown for laying out bits... Lanz of Salzburg are terrific...
