HEPI Actuator Install Progress
Jim W Greg G BSC 6 has had the NW and NE vertical and horizontal actuators mounted to the foot. The SW and SE corners have only had the vertical actuators mounted while the horizontals have yet to be mounted. The lack of room and a few technical issues have made the work a little frustrating. We should be able to finish as soon as End Y returns to laser safe.

All the actuators are now attached. The whole system dropped ~.007". While the E-W and N-S translation was only ~.003".
