VS Nose Rib Issues

I was finally able to cleco the skin to the VS skeleton. I notice that where the middle and bottom nose rib ends are, an inch or so from the leading edge of the VS, a corner of the nose rib is poking into the skin making a distinct bump out on each side of the VS. Thus, there are 3 pairs of bumps. It is the corner of the rib end where it is elbowing into the skin.

Clearly, there is significant pressure there to create this reverse dimple. I took the ribs out and made sure to smooth and round out the outside corner on this rib and rib flange end. The bump is still clearly there.

I just wanted to check/verify if others have noticed this bump too? I am partly chalking it up to still having blue plastic on the skin. Once all the plastic is off, i am sure it will help mitigate that bump.

Was there anything special people did to make sure their skins were smooth?

Thanks for the insights,
Jae

This is probably a dumb question, but did you get the rib flanges perpendicular to the web? They're typically angle out, sometimes by quite a bit, and that can make things fit funny.

Jae,

I had the same issue. We did some reshaping of the flanges prior to riveting and ironed out the dimples in the skins. Apparently it is not uncommon. See more comments at this link: http://www.myrv10.com/tips/gotchas.html

Thank you very much

Thanks for that tip. Without a human pointer, there was no way even google could do that search. What a shame, google is worth more than ebay and yahoo combined, yet cannot find me a "nose rib bump" page.

I had it too

I had the same problem with two HS ribs on my RV8. With everything prepunched it's pretty hard to screw this up. The rib was just a bit too tall--I made sure the flange was perpendicular, double checked everything. Long story short, I took my fluting pliers and put a flute in the nose of the rib, and that pulled it down.
