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.

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.
