The two support fingers on the upper resonator trolley were bent due to excessive loading during cylinder toggling.

Fingers were bent back into position such that they are vertical when the cylinder is retracted.

The cylinders used to actuate these fingers were replaced (one was leaking) - replacement allowed for the opportunity for upgrade. The following changes were made:

• Changing reverse spring-return cylinders to double-acting cylinders (formerly American Cylinder 750RVS-2.00, replaced with SMC NCDMB075-0200C)
• Addition of in-line flow controls for both extension and retraction motions
• Tuning of flow control to achieve smooth operation and prevent further damage to the fingers during actuation

 The new finger configuration has been tested and is working.
