CAP-946
S-725
The S-725 uses a gimbal mount at the front that pivots as the X or Z leadscrews are turned. These leadscrews put pressure against the leaf springs, noting the springs are not identical.
To disassemble for leadscrew cleaning, loosen the gimbal and gently pull out the arm assembly. You do not need to remove the leaf springs. I also disconnected the final head on the pivot head so that I could fully detach the arm, which was connected via a cable epoxied to the case.
The bent spring goes on the side
High resolution
S-M90
SP-100
SP-150
S-900 series
Moderate resolution (roughly 1 um). As of 2018 only the S-926 is in production
S-925
S-926
S-930
Has a fine and a coarse adjustment knob. The coarse knobs was seized on all three surplus units mcmaster purchased.
Economy
Above: 3 S-750 at left, 2 S-600 at right
Low resolution, maybe 10 um.
The S-600 was discontinued in favor of the S-750.
The handle is compatible between the economy positioners. The finer knurled handle is the original one I had while the coarser grained ones were purchased in 2018.
S-600
S-750
