I use a 22mm bearing mounted on a 1/2" shaft for centring - a technique copied from John Mills (Doubleboost) :
Slow rotating spindle. Bring bearing up to one side of work until it's outer race just stops spinning as it rubs the work. Zero DRO. Then approach other side until bearing just stops spinning. Half the DRO reading is your centre point.
No reason same method cannot be used with a gear cutter with a bit of ingenuity.
