KR> wing attach fittings.

[John Martindale]

Well I never realised that. Are the KR2S wings also longer than the KR2?

I wasn't brave enough to say it without checking, but they are 
Different.The KR2 ...which gave the spars three degrees of
forward sweep.
The KR2S uses only two different aft fittings... which yields 6 degrees
of sweep...

I wasn't brave enough to say it without checking, but they are 
different.  The KR2 had eight straight ones for the center aft spar, and 
eight for the outer aft spars that had the three degree bend, which gave 
the spars three degrees of forward sweep.  The lengths have to be 
slightly different for the bolts to line up (through the spar).  They 
are labeled in the KR2 notebook as numbers 2,3 and 4.  Not sure why they 
aren't named 1, 2 and 3.  Maybe the mains are "number 1", but the 
drawing isn't labeled as such.  Go figure.

The KR2S uses only two different aft fittings, eight of each.  They all 
have the three degree bend, which yields 6 degrees of sweep for the KR2S 
aft spar, which gives it that more tapered look, and essentially helps 
to improve the MAC forward slightly, improving stability (slightly).  To 
make this work though, eight fittings are longer than the other eight, 
so the bolt holes will line up (through the spar).  I have them laid out 
on the bench with a straight edge against them, so I'm not 
guessing...and this does verify what I was thinking, given that Trailing 
Edge Technologies made a number of these, and I still have a set (for my 
next plane)...

[brian.kraut at eamanufacturing.com]

Someone correct me if I am wrong on this, it has been a little while and
my memory is not 100% clear.

The main spar fittings are exactly the same for both the 2 and the 2S. 
On the aft spar of the 2 the fittings should all the same, but on the 2S
the spar cants forward a few degrees some of the aft fittings are a bit
longer with a slight difference in spacing from the attach bolt hole to
the holes that go through the spar.  They also have a slight bend to
them.  So basically if you bought a set of 2S fittings to use on a 2 or
vice versa you would need to remake either four or eight of the aft
fittings, can't remember if there are four oddballs or eight.

Hey Brian,

I got you started with the first bid.

Question, Is there a difference between the KR2 WAF's and those for the 
KR2s?

I had this discussion with our PFA engineers in UK, and they told me that
any unwanted blank holes in the spar should be plugged with a bolt shank.
The theory being that a wooden dowel could compress and weaken the spar..

Long time agooo!

Steel bolts in the holes pretty much precludes redrilling the spar cap
to make the WAFs fit properly, so that's not an option on this
application.  It's a moot point anyway for curing the single hole
alignment problem between the two WAFs.

Thanks for all the replies

I now get what everyone means by 'shear joint', and that one should NOT
weld anything unless you want to go through a whole hell-of-a-lot of extra
work fixing the metallurgy of the resulting part.

So far, the choices everyone has posted seem to boil down to:

1) Make new WAFs for one side using same-thickness strips of 4130, using
the old ones as a template, then drill the main bolt-hole for the
pin/attach-bolt based on where everything lines up.

2) Move the WAFs around on the spar, using dowels to plug the old bolt
holes.

My WAFs aren't really 'off' on the spar (both my old spar & my new wings
are fully complete right now - the wings were slightly damaged in transit
but nothing irreparable), and the holes appear to be the right diameter.

So it would seem that making 'new ones' from strip steel would be the best
choice, although I am open to more ideas.

KR> Wing attach fittings

[Randy Smith]

I am not sure how many times we removed Less Palmer's bolts before the plane 
was finely left at the airport. We could install the wings in about 20 min and 
remove them in about 15 min. The thing to remember is replace the Teflon castle 
nuts each time. We had a couple of blocks of Styrofoam that fit just right 
under the wings.

I have read that using the WAF's to make the plane portable is not a 
good idea as the bolts, washers and nuts will eventually wear out the 
WAF's. That makes sense. I would think a good solution ,and easy to do 
would be to make the holes in the WAF's  larger, and use bushings in 
those holes that the bolts, washers and and nuts can sandwich. When they 
wear out, I'll get/turn a new set and I'm back in business. Any
comments?
Heres the latest:
I know have 15.4 hours of flight time.  I am getting much more 
comfortable with the 172 Skyhawk, though i do believe I wont buy 
oneever. Turbulance doesn't unnerve me like it used to, though it 
does make practicing more difficult. Still, Andy (my CFI) seems to have 
more confidence in me these days. I have learned that practicing at a 
busy airport, such as GPT, is very ineffective for a beginner. The radio 
is always interrupting the lesson, and often my touch and goes turn into 
directed go-arounds. We now make the point of going west to Stennis 
(HSA), a much better practice airport for me, and the tower guys are 
real good with us rookies!
N1333A is now in my shop. I have told my customers that I'm no 
longer doing speaker repairs as I don't have the room. Actually I don't

have the patience anymore. They only burn them up again in short order, 
so its a waste of my time and effort. I am also shutting off cable TV. 
The idea is that I should be spending that time on the plane. It also 
gives me 55 bucks more a month to kick around. I'm replacing cable with 
my old TV antenna on a rotor on a 60 foot tower i have purchased for my 
ham radio activities. As for movies: Wal-Mart $5 bin when I want them!  
The web site for N1333a is:

I'll try to keep it regular as I get rid of these old backlogged

problems. I have no interest in putting much time into someone else's JUNK.

Thanks for the update. I know that N1333A came with 3.40x3.00x5 on the 
mains and 2.80x2.50x4 on the front, as well as drum brakes on the mains, 
non differential. I'm not happy with any of that. This is a Tri Gear, so 
I would like the additional ground clearence for the prop (I'm 
increasing the engine to 2180). I'm getting rid of that retractable 
landing gear and going fixed. Thanks for the info on the brakes also. 
Nothing is carved in stone so far EXCEPT this plane has got to be easily 
maintained, accessible and SAFE. Even the tri gear is up for discussion 
as I REALLY like the looks of the taildragger KR's (the tri gear is 
easier to trailer IMHO). Anyone else have ommendations on the gear and 
tires?

Please consider this carefully.  5-500 tires look (and are) pretty huge on a 
KR.  I have the "standard" 11x4.0-5 Lamb tires, on 5-500 wheels, and that 
works fine.  I fly in and out of grass strips a lot with this setup 
(including wheel pants) and it's just not a problem.  I don't know that you 
need the ground clearance, especially with a taildragger, unless you're 
running a large diameter aircraft prop.  My recommnedation would be to avoid 
Cleveland brakes and go for some like Tracy Obrien sells.  They are much 
cheaper, lighter, and are easier to fit wheelpants to.

Hey Pat. I have gotten swamped with stupid work (see speaker repair 
complaints) and in the process lost your phone#. My bad. I'm not  
fiberglassing yet anyway, but am just starting to tear it down. I have 
cut off the front deck and gas tank, and I'm going to cut the turtledeck 
off. I will be remaking the front deck and a new aluminum gas tank. I'm 
doing this because I want the room up front for differential breaks, and 
I also want to be able to remove the front deck for regular inspections 
i cant do this as it is. I want the turtledeck removable for inspections 
and maintenence also. I am also going to remove the old retractable 
landing gear and install fixed gear, disk brakes and 5-500 tires. bigger 
tires are safer on wet grass strips. This will also bring the height of 
the plane up another 5 in.If your interested in MAKING your wing attach 
fixtures rather than buying them I'll be glad to help you in any way I 
can. I hope you can make it down to the airshow. our tech advisor , 
Mickey, is going to have his latest plane out there on display. He's an 
awesome builder. If your not a member of the EAA, your welcome to come 
check us out. We'd be happy to have you as a member! We're based out of 
the Diamonhead airport. BTW..do you have any pics of your KR so far? Be 
well!

KR> Wing attach fittings - twin

[william Clapp]

Okay - time to mix it up!   I just have a couple questions.  WAFs are currently 
made out of 4130.   Can I have them hydro cut from stainless and what would be 
the difference in material strength?  I am planning for a WAF that is a single 
piece on either side of the spar instead of two.  I may also make them a little 
longer down the length of the spar (only a inch or so) and maybe a bit thicker. 
 Any suggestions?   I do believe that the stock WAFs may be just fine  but I 
need to incorporate the motor mount into the forward WAF.   Bill Clapp

Yell! I need just the outboard sets.  I have a KR2 with the fiitings  on the 
center spars but no wings for it.  I have spars but no  fittings.  It has the 
RAF airfoil.

I also need a set for the outboard wings of a  2S.  (im not sure if they

So total is two sets of outboard fitting (no inboard ones)

Let me know of price.

[Brian Kraut]

Since it seems that Rand is out of wing attach fittings I am going to have
the shop we use at work give me a price on having some sets made.  They will
be either punched out on a CNC turret punch or cut on a water jet.  I would
probably have them cadmium plated also.  If anyone would want to buy some
please let me know at brian.kr...@engalt.com.  Send an email to me, not the
whole list.

I don't have the price yet, but it should be somewhere near Rand's price or
a little less.  I am not looking for firm commitments now, just a rough idea
on who may want to buy them in the next six months so I can see how much
they will cost and if it is worth the effort.
