| Subject: | Question about Tanks |
Fellow Builders,
I have a dilemma, here is the synopsis.
I am currently working on the Left Tank and I have already drilled my Z
brackets (thank you Dan for the easy way of doing it). I have clecoed
together the Tank and the rear baffle to the tank. When I put the tank on
the spar, there is a gap between the tank skin and top main skin. The gap
looks like its somewhere between 1/32 and 1/16. I will see if I can get an
exact measurement tonight, I am also going to attach the bottom main skin
and see how that looks before I move forward.
I can also see where the holes that will be dimpled for the screws along the
top of the spar are not exactly lined up with the hole in the nutplates
(probably a distance equal to that gap I am talking about). The bottom tank
attach holes look like they are lined up fine.
Also, the leading edge of the tank seems to sit about the thickness of the
skin higher than the leading edge (just at the forward most portion where
the tank and L/E meet). Other than that, there is no gap along the seam
between the tank and L/E.
Any suggestions or insight will be greatly appreciated.Thank you
Scott & Jenni

Scott,
Does the bottom picture on this page look familiar?
http://www.rv7factory.com/log/060110.html
I asked around too, and I discovered that this was a fairly common
issue. At the suggestion of another builder I was able to help the fit
somewhat by taking the nose of each of the tank ribs to the deburring
wheel to improve their roundness (is that a word?). In other words, by
smoothing out the noses of the ribs a little more, I was able to
slightly improve their fit into the skin.
I also used some ratcheting cargo straps to snug the tank skin to the
wing, and I was able to get the screw holes in the skin to align with
the holes in the spar without too much pressure. This really helped
with the alignment of the tank skin to LE skin correct prior to
drilling the W-423 joiner plates. You can see the straps on the wings
here... http://www.rv7factory.com/log/060114.html
Good luck!

When I do that I can close the gap where the main skin meets, I am concerned
thought about stressing the skin when the tanks are mounted for good. Also
nothing seems to help the slight gap near the point of the leading edge.

Did you have any trouble getting clecos through the tank skin into the
back baffle? Did all the clecos holding the skin to the ribs go in
smoothly & remain perpendicular to the skin around them? (not likely :-)
) Have you built & installed the outboard leading edges yet? Did you see
the same problem there?
If the rib flanges are standing up even a little it can push the baffle
back a bit (will get worse when you put the proseal in there). It's been
a while, but I think I saw something similar when I built my tanks, &
leading edges, as well. I think I used ratcheting strap clamps, aligned
over some of the ribs, to put some pressure on the tank/leading edge.
Use 2/4's or something similar to protect the trailing edge of the wing
skins & rear spar.
If moderate pressure on the straps pulls everything into alignment, try
coaxing the LE rib flanges a bit, both around curved portions & the back
flange.

Question about TanksCheck to make sure your tank ribs are forced all the
way into the nose of the tank skin. That's most likely what at least
part of the problem is.

Hi Scott,
I had the same problem with my RV-9A left tank. I put the 1/8 clecos into
every hole where the screws go into the spar nutplate holes. Then I started
pulling down on each cleco starting at one end and working my way down the
line. Eventually the tank skin came down into position. More about it at:

Have a goodun!

I actually disco vered this little problem and provided the solution to
Van's some years ago.
jack up the rear spar and you'll hear it pop right into place.
there is a thread on the RV List some time ago where someone ground down the
bottom of his Z brackets. He didn't need to do that. It's the small sag in
the middle that's causing your problem.

Actually the sag is not there, I have a jack screw in the center of the rear
spar that brought everything nicely into place before I put the main skins
on the skeleton. I will however break out the fishing line again and make
sure my spars have not moved since having the skins on and drilled.

Thank you everyone for all the help and suggestions. I think my first order
of business is to pull the tank, take it apart and re-check all my rib
flanges and hole alignment (especially around the nose). I did in fact have
trouble "wrestling" the tank together.
I know that before the ribs went in; the pre-punched holes were triple
checked for straightness. I cleco clamped my ruler to them and they were
dead nuts on.
We certainly appreciate all the advice and help everyone offers.

Is your gap the same all the way around? Especially along the splice joint?
Or does it widen (or lessen) along the length of the tank or leading edge?

Subject: RE: RV7-List: Question about Tanks
Actually the sag is not there, I have a jack screw in the center of the rear
spar that brought everything nicely into place before I put the main skins
on the skeleton. I will however break out the fishing line again and make
sure my spars have not moved since having the skins on and drilled.

I actually disco vered this little problem and provided the solution to
Van's some years ago.
jack up the rear spar and you'll hear it pop right into place.
there is a thread on the RV List some time ago where someone ground down the
bottom of his Z brackets. He didn't need to do that. It's the small sag in
the middle that's causing your problem.

Push down harder on the tank. I know that sounds too simple, but try it.

Subject: RV7-List: Question about Tanks
Fellow Builders,
I have a dilemma, here is the synopsis.
I am currently working on the Left Tank and I have already drilled my Z
brackets (thank you Dan for the easy way of doing it). I have clecoed
together the Tank and the rear baffle to the tank. When I put the tank on
the spar, there is a gap between the tank skin and top main skin. The gap
looks like its somewhere between 1/32 and 1/16. I will see if I can get an
exact measurement tonight, I am also going to attach the bottom main skin
and see how that looks before I move forward.
I can also see where the holes that will be dimpled for the screws along the
top of the spar are not exactly lined up with the hole in the nutplates
(probably a distance equal to that gap I am talking about). The bottom tank
attach holes look like they are lined up fine.
Also, the leading edge of the tank seems to sit about the thickness of the
skin higher than the leading edge (just at the forward most portion where
the tank and L/E meet). Other than that, there is no gap along the seam
between the tank and L/E.
Any suggestions or insight will be greatly appreciated.Thank you

It has been a while but I do remember I had a similar problem. I was able to
get them to a 64th gap. Was still determined to get them (aft edge tank to
leading edge of top skin to meet. So I called Van's and got
Ken................. he said , rather harshly, 'You don't want them to butt
to each other". "Why" I asked. "Because the paint will crack along the seam
line unless there is enoug room for the paint to fill the gap". My plane
isn't painted or flying yet so I can only take him at his word. I have found
him always to be correct when I follow his advice. Plus I have found that
many times I will take great pains to get everything nearly fiberglass
smooth when clecoed only to have a bit of a shift during riveting. So get it
close as possible with no stress and move on. Ain't it fun.
