I've looked for the specs on the gearheads. I've got several
PH66-01GK Vexta steppers with 2GK18KA gearheads. I've managed to
crossreference the motors, and found the specs on the motors (I
think), but the gearheads remain unavailable, spec wise...

Any pointers?

I'm thinking of driving the fine feed on a Grizzly Mini-mill with one,
I've got a Z axis DRO, so I'm less worried about backlash than
otherwise.
