Jesse...you're good to go with those .040's that I cut out for you and yes
add the lower gusset/doubler corners on the bottom cabin skin that I
described to Jean. My airplane doesn't have this...but I'm sure a couple
more summers and it will need it. It took Howard's a few seasons to start to
show signs of buckling/oil canning behind the forward gear attach
area/carrythough. Is why Bob's XWI has the gussets/doublers there.
The only damage that will happen at the rear (drag brace) gear fitting
occurs if the aircraft gets stood on it's nose (or into a big chuck hole)
and the drag brace gets driven up into the fus..buckles the double bulkheads
that hold the fittings. This is a good thing IMHO as it's very easy to fix
with minimal "dissection", compared to the consequences if you reinforced
the area just in case. Just be sure that those rear drag brace fittings get
installed with 3/16 x RV1613 rivets and NOT 1/8 x RV1410's. I've rebuilt one
Rebel that had gear failure and only because they missed that "up drill"
spec in the manual.

Wayne,
I have two questions:
1) With the .040 fus-26s you gave me, do I need to add extra stiffeners to
it (other than the triangle gussets you mention)?
2) Has there ever been a need to add gussets around the openings where the
rear gear fittings protrude?
I plan to be rough on her, both on wheels and floats.
Thanks
Jesse

..oooh and don't let the picture throw you off. I also add an extra
bulkhead
in the cabin floor, positioned between the rear drag brace pair and what
would be the most forward one before the carrythru. Not totally
necessary..but I like to add it anyhow for rigidity.
I also now add a triangular gusset to the cabin floor, about 8" in size on
each side, tied into the Fus-35 angles on one edge and out onto the 2"
square carrythrooughs with the other. This helps keep the area right
behind
the main gear leg attachment (FUS-2) from deforming when on floats. I'll
see
if I can dig that one up for you was well.
