[dsg-hallb_rich] [EXTERNAL] Re: Test of Grainger springs on mirror mounting points

[Marco Mirazita]

Hi Tyler,
there is one piece missing. After slide 4, the flange is fixed on the 
spring by a conical washer, a spherical washer and then the nut.
I attached here drawings of the two washers and of the full assembly.
Let me know if you can find all the parts, we can have a bluejeans 
meeting if you want.
Marco
