fus-27 flange

Joel Jacobs · Post by **Joel Jacobs** » Fri Feb 17, 2012 9:21 pm

Hi Folks,
I've been battling that fuselage root rib flange a couple days now with not
much success. I tried sandwiching it between two strips of 1/8"X3/4" iron
strips an using C-clamps as suggested and it did straighten the flange but
the rib will no way lay flat on the table like the manual says. I'm either
going to have to buy a shrinker or flute the flange. Will a shrinker be
handy for anything else? I don't want to buy one just for this piece. Is
the flange visible from inside the completed cabin? If not I'll flute it.

Joel

P.S. www.harborfrieght.com has a shrinker/stretcher set - not one machine
with both jaws but two machines - for $149.

How crooked is the rib? Mine wouldn't lay completely flat after
straightening the flange with the method you used but when I positioned it
in place and started drilling and clecoing, things fell into place pretty
well. It probably still has a minor wave to it but I can't tell by casual
observation.

The only way to get root rib straight is to use fluting pliers. You are going
to need these pliers for the ribs in the rudder and elevator as well... and for
the roof ribs that are aligned parallel to the root ribs.

The biggest warp is right at the first few inches from the front - the part
just above where it's cut out to fit around the top carrythrough/gusset. If
I lay the rib on the table, the very front of the rib where the flange
starts is contacting the table but just 2" back it's about 1/2" off the
table. When I flattened the flange that front section just curled right
down. I think I'm going to need to do something before I'll be able to
start drilling and clecoing. I think it'll look alright if I put a few
flutes in it. I'll lay out where the rivets will be and do it between them.

Hi Joel !

Fluting is probably a lot easier ! Just be sure to flute
BETWEEN the rivet holes !!! ;-)

The shrinker-stretcher is useful for the corner wraps between
the aft cabin and the fuse, and is essential for building the floats,
if you go that route ...

Yeah, I've about come to that conclusion. I'll spend an evening and try to
make a pair of fluting pliers. I'm thinking a pair of vise grips and three
pieces of 3/16" drill rod should do it - two on the bottom jaw and one
between them on the top jaw. I'm just trying to invision the correct
angles.

Joel

P.S. If any of you folks have a set and a digital camera I would sure
appreciate it if you could email me direct a picture of the business end...
Thanks!

Well I don't plan on floats. Not many seaplane bases around here! I think
I'll try hammer and dolly on the corner wraps because the shrinker would not
leave a very nice finish on the outside of the plane. I have four extra to
experiment with since I upgraded the thickness.

Joel my fluting pliers are made from a set of regular slip joint pliers. I
just unbolted them and ground matching curves in each jaw then bolted them
back together again.
Drew

P.S. If you're near centralia ont you can come over and use my shrinker
strecher

Hi Joel:

Went to the House of Tools and bought a pair of flutting pliers. This did a
good job. I took a pair of flat nosed pliers and flattened the area where
each rivet goes so the rib and skin are tight together. Don't fully crimp
first time around as you can go back and crimp some more if not enough the
first time.The only trickey area is right at the front where the flange is
the narrowest and the curve the sharpest. Takes a little Quirking here.
You'll see when you get there.

GOOD LUCK

My Shrinker chews up the metal enough that that I prefer the fluting
pliers for most things. Maybe I'm paranoid about cracks developing. But
hey, I agree, another tool can't be a bad thing! Of course my wife isn't
quite so sure....
