ever sand an EZB rib?
 
I once had a model with diagonal ribs, scratch building it of course. I
used the straight rib template for all of ribs...hmmm...so I thought I would
sand the straight ribs to match the diagonal ribs from LE to TE...bad idea
too...but one does learn. Looked pretty bad after covering too...I'm older
 now and don't make those mistakes.

Is that what sanding blocks are made for?

IMHO, if you cut a diagonal ribe and a straight rib for the same chord,
the diagonal will be longer - therefore even tho it's the same profile
it eill have a higher "high point' as it is longer. No question there.

Now, as it is diagonal the high point will be closer to the leading edge
that if the same length was perpendicular _BUT- will that high point
now be at the same percent of chord as a straight ribthat that fits the
chord ?

How about them beans ???
