Rex,

The latest drawing is now 
at   http://bnordgren.org/seismo/FBV/FBVmech4c.zip   Its in AutoCAD 
2000  format, so you should not have any problems.  At one time there 
was a 4d version, but this, for whatever reason is now the most recent.

The drawing has 33 layers which may be turned on or off for 
display.  For reference the layers ending in -DIM are dimensions for 
the various parts.  The ones ending in -HDW are of the screws, etc 
associated with each part.  As with all the Inyo FBV documentation, 
it would be a good idea to check with me before trying to use it to 
cut metal as there may well be a later version.  This project is 
still evolving very slightly, particularly as more people get 
involved who are making suggestions and finding documentation errors.

I never learned how to use Layer 0 properly, so if my drawing is 
strange in that regard, that's the reason.

For people who don't have AutoCad, an alternative way to view and 
print, though not edit the drawing file is with the free Brava! dwg 
viewer, which can be downloaded from:

http://www.infograph.com/products/dwgviewer/

That seems to work with all versions of dwg files.

Good luck,

Brett
