Swiss Cheese Baffle Damping Complete
Damping completed and flanges back on. No hitches. Three viton corks are in, preliminary laser vibrometry looks good. More later.
Gerardo, Vinny, Robert
First picture: Robert looking through the viewport at 9 o'clock position while inserting his hand into lower viewport hole at 8:00 position.
Second picture: A view through the lower viewport hole at 8:00 position. Black viton cork is inserted between the rib of the baffle and the chamber wall.
Just to avoid any future confusion, the pictured location of the cork just above was not the final position. Based on feedback from the laser vibrometer, I moved it to 7:00, as pictured in the follow-up link given by Stephen.
