Don,
It might be better to install "butterfly" blocks between the spar caps
at the attach point with the steel fuselage (similar to the landing gear
attach blocks seen on Lynn Hyder's KR2--
http://home.hiwaay.net/~langford/lhyder/)--
one 1/2 " bolt through the block and an attach fitting welded a
If you have a Sonerai in your neighborhood you might
look at how the wings are pinned to the fuselage in
that example, tail components could be attached using
the same techniques.
Basically, the wing center section is pinned to the
fuse through the reinforced center of the shearweb
with bolts via
that's an idea for thought. I'm getting ready to start machining parts
Don Reid suggests that the waf's almost as they are, are probably sufficient
my view is that how the spar sets are attached to the stock fuselage it
shouldn't bve too hard to come up with something at least that structurally
so
just to get a dicussion going. I have a hypothetical question to the net and
I'm sure it's been either done or thought about.
If one decided to mate a KR wing set to a truss type steel tube fuselage
how would one go about doing it?
. My thoughts are to go with a Sonerai 2 style set up
as it is
Interesting idea, I'll let others comment on the more
technical aspects of your post, but I would be
interested in the weight difference between the wood
and steel fuse.

just to give an idea the Sonerai 2 S uses About an equal amount of 3/4 inch
5/8 inch .035 steel tube with some other sizes and calls for about 150 feet of
tubing. 5/8 tubing is.2205 lbs. per foot and 3/4 tubingis.2673 lbs per foot if
you
do the math it weighs approx 36 lbs. I have a Smythe Sidew
36 pounds, without covering or paint. Sounds like it
might be twice as heavy as a well finished wood fuse.
Am I close?

It depends on what kind of finish you want to do as it lends itself to how ever
you want to cover it. Finished fabric covering is the lightest at 6 oz. per
sq.yd
with fiberglass sheeting coming in second or last depending on how well you do
it to
aluminum covering being the heaviest .025 2024T3
Interesting Don, thanks for the info.
I have a wooden fuse in the garage now, but I've
always wondered about a steel tube substitute based
loosely on the Sonerai. Looking at the numbers you've
provided it might be possible.
I've always thought that a wood stringer and fabric
turtle deck would loo
I have forgotten what my KR fuselage weighed, but my son is building a
cassutt and the steel fuselage weighed in at 45 lbs.
