Adjustments were made in the order listed.

Coil B DS OOPS (B2) Tightened ~1/6 turn  (60 degrees) 
Coil B US OOPS (B1) Loosened ~1/6 turn 

Coil E DS OOPS (B4) Tightened ~1/24th turn (15 degrees limited by potential gauling)
Coil E US OOPS (B3) Loosened ~1/12 turn (30 degrees) 

Resulting forces captured and displayed 
Summary:
B1 down in force by 228 lbs
B2 up in force by 184 lbs
E3 down in force by 152lbs
E4 up in force by 52 lbs

All other OOPS had no changes.
Main Y supports had some small but inconsequential forces changes
Main Z supports  had some small but inconsequential force changes
We will check the results of the changes at full operating currents of the Torus  ( positive and negative) with the Solenoid at full + field over the next few days.
