[Dsg-rich] Update to the Trolley Parts

[Amrit Yegneswaran]

marc, 

this is really puzzling. 
independent of dario, bob approved the drawing. 
so, howso? 
perhaps, rather than sending G&R the drawings a sheet or two at a time, the entire set which goes together should be looked at, approved, and sent. 
and perhaps we should freeze the drawings after this round, rather than improve upon them. 
leave good enough alone.

Hi Dario, 

GandR just called and requested that you review the Trolley parts 
drawings. Sheet 3_8 and 6_8 of the updated drawings have hole spacings 
on the I-beam of 2.3 inches but the lateral and central counterplates on 
4_8 and 7_8 were not adjusted. So the drawing has them at 2.5 inches. 

Please review the drawings and communicate changes with Bob Miller. 

Bob, 

After you approve of the changes please let me know and I will forward 
the info to the shop and tell them to proceed. Currently, they are 
holding on the Trolley parts. 

Regards,
