[DML] Re: Galvanizing the Frame

[mike.griese@xxxxxxxxxxxxxxxx]

Lotus had 2 things going for them.  First, they had the relative 
luxury of numbers.  They were able to afford fixturing that would keep 
the frame rigid while it was temperature cycled.  This helped prevent
warping.  Second, they had experience.  They ran enough frames to 
be able to modify the design to minimize warping.  It is entirely possible
to build a fixture for a DeLorean frame, but that will significantly drive
up cost, particularly for the first frame.  There isn't much you can do 
about the design at this point.
