The first five flanged domes, are now inserted into the holes of the stainless steel plates.  
Because the bottom edges of the domes protruded through the first plate a little bit, the second plate 
can also be attached and is perfectly lined up with the first one.  The previously drilled holes in the flanged 
domes are now used as guides in drilling all the holes in the two stainless steel plates.  The holes in both 
stainless “top” and “bottom” plates are drilled simultaneously, so that all holes line up perfectly.
