You will find that the rim isn't the same thickness all around, especially 
when you cut anything based on that assumption. You may also find that it 
is just as easy to lay the panel on top of the rim and mark it from 
underneath with a pencil, outlining the inner edge of the rim, and 
dispensing with the pattern altogether. Mark the belly rail after the rest 
is fitted to your satisfaction. Marking rib placement from underneath with 
a pencil works where you can reach, but the last few ribs are difficult, so 
you might either be back to making a pattern, or pin locating ribs on the 
panel as we discussed pretty extensively a few months ago.
