3.2.4 Attaching the head stage assembly
The headstage assembly is mounted to the front of the rotary stage. It can be mounted using
either of the pairs of channels on the rotary stage (marked ‘a’ and ‘b’ below). Each channel
contains four tapped holes, two of which should be used to secure the dovetail slide.

assembly being fitted
The sliding carriage is locked in the required position on the dovetail slide using the thumb
screw. The sliding carriage is designed to accommodate a range of dovetail based
headstages including Axon headstages. The dovetail headstages are secured by tightening
the dovetail clamp using a 3 mm allen key.
In addition there are two M3 mounting holes on the underside of the sliding carriage that can
be used to attach a sub-mounting plate to attach a wider range of headstages. The PS-7650
head stage plate can be fitted using these tapped holes.
