Alphason HR-100S Arm

Can anyone suggest the method for adjusting cue height on this arm? I'm stumped and was wondering if any fellow goners had a recomendation before I start probing around orifices with a .035" hex wrench.
The queing height is adjusted with a tiny (might be .035 - never checked the wrench that closely) hex nut on the side of the plastic platform. The whole cylider can be moved up or down (as well as rotated) once the nut is loosened.

I'm at work, but from what I remember, the access hole comes at an angle.
