[Halld-tracking-hw] Plastic Parts

[Tim Whitlatch]

Hi Curtis,

This all sounds correct. One comment. If the feedthru or donut come out 
slightly large in some areas (.0005 or so), does it make sense to go 
through another iteration? Should CMU just sand each piece if needed?

The delay will be approx. 6-7 weeks for these changes. I am guessing a 
few thousand dollars for the changes to the mold.

Cheers,

       Tim
