Hhmmn.  We're they warped or dimensionally inaccurate?  I know one of 
the attractive things about extrusions is that the extruding process can 
be less expensive than other fabrication methods, IE: machining from billet.

Yet, that same inexpensiveness does come at a price, as extrusions can't 
hold the same low tolerances as other fabrication methods.

Nope, have not looked at Lansing.  In fact, never heard of them until 
you mentioned them.  I will take a look at their page tonight and see if 
they've got a size in the ballpark that we need.

In other news - in the Ten-Tec arena, I received some feedback from them 
today on RF shielding.  They are aware that the plastic bushings do 
prevent the top and bottom case halves (clamshells) from grounding to 
the case innards.  They've never produced a factory solution but did 
offer a rather simple way to shield the case.

If we end up using Ten-Tec do to the End Panel fabrication and a custom 
enclosure, we might could get them to incorporate shielding in our run 
of cases...
