--> RV7-List message posted by: "Steve Sampson" <SSampson.SLN21@london.edu>
Andrew - a slightly different perspective to most of the other replies. I
have just squeezed the last rivet on an RV9a (though not flown it yet) and I
have done it all with a Tatco squeezer and a 2X gun. I am no expert but most
of my rivets are OK and I always preferred squeezing to gunning. It is
tiring on the hands though and if building a second I might get a bit more
oomph to save my hands. Perhaps a main squeeze.
My thought is that you are probably not getting the rivets quite in the
center of the dies since early on when I had them off centre I had similar
problems. In view of the fact that the dies are as you say convex this
appears to matter. Hope this helps, you will win! Also make sure there is no
crap UNDER the die where it slots in, and check them for symetry.
By the way do keep an eye on the rivet call out for accuracy. I am sure,
thinking back, some of the required lengths were too long when calculated.
This is true of bolts also.
Good luck, Steve.

| Subject: | RV Newbie Question |
--> RV7-List message posted by: "Dan Reed" <dreed@qualcomm.com>
Hi All-
I just completed my RV-7 HS from an early kit that required building the
jig. While I was looking over my work (and a few minor mistakes).I noticed
something that has me concerned.
On the top left hand skin closest to the root and furthest aft I have a very
slight amount of "oil canning". The skin feels like it should be a little
tighter in this area. If I press down lightly on the trailing edge of the HS
it feels a bit better, but still just a little less taught than the opposite
side.
I was wondering if anyone had ever experienced this. And if so what they did
to rectify it. I am only about 30 min from Vans and am considering picking
up a new HS to complete while I await the arrival of my QB in February. The
second one always comes out better right?
Any help would be greatly appreciated!
Thanks-
Dan

Dan,
There is an unwritten convention among RV builders at fly-ins - never look
too hard at, or offer criticism of, a fellow builders empenage - that is
where the learning curve is. So please show me the empennage that does no
have some oil canning.
By all means seek advice from Vans, but I am pretty sure that the advice
will be - ignore it. It is unlikely to be an airworthiness problem. If you
have ever flown in an aluminium glider (L13 Blanik)in turbulence or aeros
you will hear a symphony of oil can bongs boings and bangs.
The only sure fire way to avoid oil canning is to get a hot air blower as
used on heat shrink and warm the area you are riveting. It will cool after
riveting to a lovely taught finish.
Once you have built in oil canning it will be there for you to admire
forever.
Keep on building - you can look forward to much bigger mistakes to solve -
trust me, but dont ask me how I know.
Regards, VH-ZEE, Canberra, Australia
