Same to me, 2 years ago
Hello
Look at this
thread I had the absolut same problem and Vans did not really helped!
I also get contacted by an RV-10 builder with the exactly same problem, the spareflange are not clean bent, they are not 90?!
Here are the design mesurements RV-7 (from Vans):
- bottomflange inside 89?
- topflange inside 88.5?
- gap between them 7.63",
- but the average of the ribs have 7.67", so I go for 7.67" and bent the flanges back until this mesurement more or less was ok, I can not change the webheight.
I also shimm the noseribsribs in this area with "liquid shimm" before I riveted, so there is no niveau step, there is now a slow transision to the slightly higher web. In the meantime, I finished my wings and yes, there is a small unperfection in the profile curvature because the web is slightly higher on one wing.
I let mesure a few other builders the gap between the flanges on different positions on finished wings or spare only, the distance vary quit a bit!
Also I found out that the ribflange hole to the spare web holes are not really in line, there are alot of builders that have this issue also, They are CNC-Punched they must line up is the answer you will get, but it is on the manufacturer to controll this and not only lay on the ... its CNC it fits ... speach!
I hope this helps you a bit,
regards, Dominik
