Adjust Quad Reaction Mass Weights
Balanced and aligned the Main Chain of Quad-2 by raising the blade tips on the Top Mass and the UI Mass. Had to reset one of the Blade Clamp units, because the blade was touching the Z-Tip Adjuster and the blade tip was still low. Leveled the Main Chain Top Mass and UI Mass with a bubble level. The Test Mass is still about 1.5 – 2mm low.
 
We removed the Penultimate and Test Masses from the Reaction chain to adjust the weights to account for the heaver glass masses. Increased the weight of the Test mass to 26130g and lowered the weight of the Penultimate Mass to 53139g. The combined weight for the Main Chain Penultimate Mass and Test Mass is 79268g and 79269g for the Reaction Chain. 

The Reaction Chain masses have been re-suspended and we are going through the balancing and alignment procedure.
