Fuselage bottom skin to wing bottom overlap

dbaflyer · #1 01-21-2014, 04:21 PM

I am working on the right wing right now and where the bottom fuselage skin overlaps the bottom wing skin (#8 screws to hold) the fuselage skin does not fit flush with the bottom wing skin. This is looking from underneath the right wing toward the fuselage. 2/32nds and 3/32nds gaps

It's been a while since I worked on this for my 6 but iirc I had same issues and didn't know how to fix it so I left it as is. It's on the bottom parallel to the airflow and being that I was getting oh so close to flying didn't want to put much time into something so hidden and inconsequential.

It may be more visible on a A model though. Perhaps others will offer better suggestions than I. Good Luck!

What is your current spacing ? If you push down in the middle .. will it lay flat then ?

I have not done this part on mine (RV6 slow no hole) yet ... when I do .. and if I have the same problem.. I would look at two things ... put a shim strip of lets say .025 or .032 .. along the full length - and or .. add another screw and nutplate in the middle ......

It might fit better if the fuselage is on the gear,looks like its on a cradle?might take some of the stress off of the bottom skin.

Also when the holes get dimpled it might take some of it out.

Seems like it would help to break the edge of the skin with one of these: http://www.cleavelandtool.com/Edge-F.../#.Ut_OFafTnIU

Use the edge rolling tool it will help. I had the same issue on my 6

My 9A looked like that too till I got it on the gear.

I had the same problem with my 9A (sitting on the gear) when I mounted my left wing last week. I broke the edge over just a bit with the edge rolling tool and it's much better now.

To get my wing incidence equal, I was up against max edge distance on the rear spar on one wing. As a result, the bottom of the fuselage and the bottom of the wing don't match up very well on that side at all. Uglier than yours by far. I'll not be encouraging anyone to crawl under my plane at fly ins!
