Full Description: *

Add 6 bubblers (3 per cavity), plumbed individually (the permanent change may be ganged), and 2 thermocouples (1 per cavity) to tube mold #2 to accelerate the directional solidification across the "floor" of the actuator opening. ?The attached Magma simulation shows the locations of the 6 bubblers. Dan Metzger will provide models for the bubbler locations. Also implement 3 functional changes to tube mold #2: extend the OPE core pick finger under its core print and increase the draft and radii in the pick finger, open visual access to the OPE gib areas, and add small uphill metal turns to the core locating towers. These three functional changes are outlined in the second attachment.
