I make all the double helical gears that go into a gearbox - four
different gears in this unit. If the gear module for the bull gear and the
intermediate gear are the same (these are the two individual gears that
mate), and the gear module for the high-speed pinion and high-speed
gears are the same (these are the other two individual gears that mate
in the gear box as well), is it then possible to just use two hobs in this
setup to make all four gears, since they mate together with each other?
We are currently using a different gear hob for each gear.
