[Dsg-rich] I: Drawings update

[Dario Orecchini]

Hi Bob,
in agreement with Marc suggestion, I send you the updated files of the beams necessary to kept the RICH on the trolley.

Have been modified the position of the interface holes with the “Strongback Interface parts”.

On the attached pictures are highlighted in yellow the old dimension (picture: before update) and the new dimension (picture: after update) for both beams, “Forward” dawing 3_8 and “backward”  drawing 6_8.

Obviously, also the related assembly drawings have been updated (drawings: 2_8 / 5_8).

Oggetto: Re: Drawings update

Hi Dario,
Please contact Bob Miller and discuss the changes you made to the drawings. As the senior engineer in Hall B, Bob needs to review the changes before we can have GandR proceed with the Trolley Parts. 
Thanks,
Marc

Hi Marc,
unfortunately after some further checking, I found mistakes in the position of the interface holes to be done on the beams necessary to kept the RICH on the trolley.
We are speaking of few millimeters but enough to give problems.
Hoping this components are not yet completed, I send you the update drawings and I ask you to transmit them to the company as soon as is possible.
 
The drawings are:
