Hi Gil,
 Today Rod and I bonded  the three honeycombs to the first ( bottom) 
carbon fiber plate using the new fixture.
All went smooth , we measured the honeycomb strips individually , found 
one side ( left) differed  from .1915 to
.194,  the center .1965 to .1935 , and the other (right) .196 in one end 
.191 in the middle and .193  end.
 as it was we did a dry fit on the vacuum fixture running the dial 
indicator , and were getting rocking motion, very uneven surface .To 
cure the problem   set  600  double back sandpaper on the granite slab , 
set shims
and  worked  the  honeycomb plane to .194 this took all the high spots 
out. Re did  the dry fit  and ran the dial indicator up and down as 
lateral ,, the indicator stayed @  0 . Then we proceeded on the bonding 
. added the weights and  re ran the dial indicator to re check .....it 
was 0 all the way through again...
here are some pictures of what we did  on the sanding  and bonding.
Mario
