Yes, that is the setup I have. I've heard that the strobe on the VS is a
bad idea as you get reflections in the cockpit given it's location up high
on the VS.

| Subject: | Tips? Riveting the RV-7/9 side skins to the baggage bulkhead/bottom |
skin curve
--> RV9-List message posted by: "Mike Hoover" <mikehoover@sc.rr.com>
Paul,
I recently riveted those five or so rivets in the curve. I had a bucking
partner to man the rivet gun while I held the bucking bar. The 706 bulkhead
flange tabs need to be bent outward to fit snug against the skin. Mine were
not bent enough so I had to push them against the skin while bucking. To
achieve this, I used what I call a "nib" for lack of a better word. It is a
3/16" +/- length of 1/4" black rubber tubing I had on hand (got from Lowes
in the garden dept. a long time ago). The tubing is thick walled and rubbery
so it works well. The inside diameter will accommodate 3/32" and 1/8" rivets
shafts nicely. You slip the "nib" onto the rivet shaft and then put the
bucking bar over it like normal. When you hit the rivet with the rivet gun
the first few strikes, the "nib" will force the flange tabs up against the
skin nice and tight. Once the rivet has swelled and the flange tab is held
against the skin securely, remove the "nib" and finish bucking the rivet to
proper shop head. I have several "nibs" in my tool tray cut at slightly
different lengths.
Hope this helps.
Mike

Subject: RV9-List: Tips? Riveting the RV-7/9 side skins to the baggage
bulkhead/bottom skin curve
--> RV9-List message posted by: "Merems" <merems@cox.net>
Fellow builders,
I am going to be riveting the side skins on in the next day or so. I am a
little concerned about the 5 or so rivets that attach the side skins to the
bulkhead at the bottom skin of the bulkhead where you form the bend near the
F-623 rib. I have bent the tabs as best I can and I know from experience
this could be on of those areas that you may dent the skin during riveting.
Any tips for riveting this area? How many of you used bind rivets in this
area?
Paul

| Subject: | Wavy Aileron Skin |
--> RV9-List message posted by: "Chenoweth" <chenoweth@gwi.net>
I'm just beginning the riveting stage of aileron assembly. One of the aileron's
skins are very wavy at the trailing edge - two or three big waves with an amplitude
of about 1" - before I cleco the AEX wedge to them. The waves developed
when I clecoed the leading edge skin to the spar and to main skins (prior to
this the skins lay absolutely flat) so clearly the problem lies in the effect
of attaching the leading edge skin. Naturally I discovered this during the
early stages of getting the AEX ready for drilling but between hope that it would
work out and Van's comment (paraphrased) "That's just the way it is sometimes"
I continued.
Now when I cleco the AEX into the waves they pretty much go away, the skin seems
to be a bit wrinkled, and the TE is anything but straight.
The other aileron does not manifest Any of this - lies flat - behaves - looks great.
Does anyone know what causes this? What, if anything, can be done to fix this?
What the affect on skin appearance will be if nothing is done other than to
Proseal the AEX to the skins while they are held straight with an angle?
Thanks very much,

I have the same problem. However, the skins did not get the waviness after
riveting. It happened after I etched and Alodined and primed the skins. I
attribute this to stretching of the skins with all the manipulation one has
to do to in this process. I think Van needs to give up a little of his Total
Performance and make these skins out if .020 instead of .016.
I remade the trim tab and placed an AEX in order to keep it with the same
esthetic line of the elevator utilizing .020 skin stock. It came out great
with no wave.
Haven't riveted the the aileron or flap trailing edge yet.
