KR> Sanding Blocks

[Wayne Tokarz via KRnet]

I also build R/C planes and the hobby shops sell sandpaper on the roll for 
about 5 -7$ It has a sticky back and you can stick it to almost anything, angle 
iron/aluminum, edge of 2 X 4, etc. worked great for me.

Rap the sand paper around three sides and staple the two sides that you don't

As my kids would say,(text?), ROFLMAO,   I too have  a Piet Oscar, love it,

I do give it that test every night, and the biggie for me is the flap
installation.  I just got the proper bolts and pins to install it last
night, and won't get the last key part, a new brush pack for the motor,
until Thursday.  Like Larry, landing it without some kind of deployable drag
makes me very uncomfortable on my short and narrow runway.  Of course I
should probably just learn to land slower...

KR> Different materials

[Wayne Tokarz]

WOW, some serious mileage on the topic! I have de-bonded and re-bonded the
wing skins on a Grumman Cheetah,  very cool system very similar to hot melt
glue, Aluminum bonding is not black magic, and can be easily learned like
any other process, ( wet lay-up on foam?:)LOL ), it all comes down to
comfort level. I think it is a bad idea for anyone with low
experience/confidence/background, to be re-inventing the wheel. I think it
is great to experiment as many of us do with this great sport, but it should
always be undertaken with a modicum of knowledge of what we are attempting
to do. As said in one of my past posts, I once ran across a stock KR2 that
was all wood, the old guy did an amazing job and it looked perfectly
functional. I will note that the wings were perceived as being heavier than
others I had run across. I think in a situation like this it is best to pick
a design one is comfortable with and go for it. 
  Gary Morgan sure has some neat little planes, did he not once own a KR and
was it not a feature photo on the group site? Red Trim?  Plywood over foam
will yield an identical bond to fiberglass over foam, your peel point will
be the underlying foam in both cases. I would imagine the same would hold
true for most any substrate over foam, the foam itself is the weakest link
and more than adequate for the application as proven over years of KR flying
and abuse.

Just mho

KR> New wing skin idea or not so new....

[Wayne Tokarz]

Hi Gary, Many years ago a friend of mine acquired,(in a trade), a "stock" KR
with trike gear and wood wings and turtle decks, even the canopy frame was
wood. As I recall the builder, (completely unknown to me), used about a
3/32" or 3mm birch plywood, over wood ribs, bulkheads, stringers, etc. He
was quite the craftsman. I lost track of it and even tried to find it again
years later, but never did. I recall we did a weight and balance on it and
I'm pretty sure it was fairly good for weight. No reason why it would not
work and be perfectly fine. Lots of work to get all the ribs just right.

Wayne

After looking in the archive, I didn't find results for wood wings.  Has
there been discussion about wood wings similar to that of GP4 or Tailwind?
Has anyone done this?

Gary

KR> New wing skin idea

[Wayne Tokarz]

  Just remembered this one, did it years ago on a special project. Use any
core you wish for front and back half of wing, and last a foam in the center
area. Cover the spars with a releasable covering, (please don't laugh, but
duct tape works really well for this!), lay up the whole wing as per normal.
Cut the leading edge and slice the trailing edge, remove only the top or
bottom half. Do your backside layups on the two skins and bond it all
together. This is just the basic idea, I'm very sure you are more than
capable working out the details, ( gas cap, lines, baffles, etc.).

Just my humble two cents worth.

Subject: KR> New wing skin idea

Hi guys
It is my plan to put full length wing tanks inside my wings between the
spars but because it is common practice here to use polystyrene for a core
and we all know what happens to poly foam when it even smells fuel, I have
been trying to come up with a way to get rid of foam all together without
having to produce a set of molds. I think I have a plan.

The cores are hot-wired from foam blocks as usual but the core that we would
normally use is discarded. The "female" form, which is cut with the washout
already set in it laid out on a flat table. A thin sheet of mylar or similar
is cut to the required dimensions and laid inside the foam form. Glass is
then laid up on that with a core material.
The skins can be made in three pieces: D box, centre section and trailing
edge, all with "overlap" for bonding over the spars.
All these can be bonded together over the spars.
This method, if done carefully and accurately should produce a pretty fair
wing skin that is strong, light and need very little fairing. Final washout
can still be tweaked at final bonding.

Any thoughts?

KR> The KR2 or Sonerai 2 is a funeral waiting to happen

[Wayne Tokarz]

I would not lose one second of sleep, or give this guy one moments thought.
The internet is full of uneducated idiots who will spout off senseless
verbiage. It is very clear that this individual knows very little about
flying. I have been flying for over 32 years with mostly tail wheel time,
his comments about nose wheels is ludicrous. I used to own a 701, and the
nose wheel is a hindrance. I will never own another Zenair . KRs and
Sonnerais are GREAT little airplanes and a lot of bang for the buck.

I realize that a lot of time has passed since the Gathering last October. I
have planned on writing about the trip, but could not either bring myself to
do it, or did not think about doing so when I had the time.





After having worked diligently for almost a year, building and installing
wing tanks, removing the header tank, and installing my new Corvair engine,
in 2012, I was ready to head to the Gathering that year only to be sorely
disappointed by the onset of bad weather. Then arriving at Mt. Vernon, to
find that the weather was great for the duration, I was determined to make
the 2013 event.





But, not being able to help myself, I decided to install a new instrument
panel, which resulted in a complete re-wiring of the aircraft. I was able to
complete the task several weeks before Gathering time and just in time to go
to Camden to get my new Dynon Mode S transponder, certified. However, on the
trip back to CUB from Camden, I bounced and landed a little too much nose
down, which unknown to me at the time, caused the prop tip to strike and
severely damaged the prop. In an almost panic, I cried out to the KR Family
for help and it was not long before help arrived in the form of a Sterba
prop from Mark Langford. I could not install the spinner, so had to fly to
the Gathering without one. The important thing is that it got me and the
Black Bird to the annual celebration.





I departed CUB at about 10 am on Thursday morning, intending to fly on auto
pilot at 8500 ft, under ATC control. So, right after takeoff, I contacted
CAE and was set in the system and proceeded to climb to 8500. While
climbing, I tried to activate the Autopilot, which tested perfectly on the
ground, but it would not acquire. I kept getting an error on one of the
servos, so accepted the fact that I would be doing all the flying. 





The flight was un-eventful as I was passed from station to station on the
route to MVN. Not long after I started flying over the Smokey Mountains, I
began to encounter scattered clouds and did not want to get stuck below
them, so called for permission to climb to clear the clouds and permission
was granted to climb and remain VFR. This was repeated several times as I
got closer to the mountain range peak, which on my route was 6000 ft. I
began to see towering clouds in the distance and could tell that they were
thunder storms as confirmed by my Dynon Skyview. It was so cool to watch the
two towers grow, one taller than the other, until the tall one began to
break up at the top and the other stopped growing These towers were 2 or

3

thousand feet apart, and I had my sight set on flying between them. I knew
that once I cleared those, I would be heading down the other side of the
mountain range into the valley to my fuel stop. I had been climbing for
quite some time as I was almost mesmerized by the cloud cover and the two
towers that I was about to travel between. I could not help thinking about
what was happening and how impossible it might seem to some who had never
experienced such an adventure. It was almost like I was not there, like I
was outside of myself, watching a guy who built a box with wings on it,
flying between two towering clouds, a lot like I had experienced when
travelling in an airline. But it was me inside that box and as I was about
to cross over the peak and head down the other side to Upper Cumberland
Regional Airport in Tennessee, when I happened to notice that the Black
Bird's Corvair engine had taken us to almost 14,000 feet. I then realized
that I had been over 10,000 for some time now and began to check my physical
condition to be sure that I was not suffering from any delusions. I seemed
OK, but knew that I had to get down soon, so

KR> Ercoup flying

[Wayne Tokarz]

I owned my ercoupe for quite a number of years and put hundreds of hours in it. 
The limited elevator was but apart of it. The controls were another very big 
part of it. Also there were no springs between them. There was a mixing 
bellcrank under the baggage bag. It was all hard connected with rod end 
bearings and had a very specific rigging procedure. I completely rebuilt mine 
in about 1986. It had a lot of dihedral and was capable of a lot of crosswind. 
Very easy to land, but still a lot of fun.

KR> gathering forum idea

[Wayne Tokarz]

Having owned a body shop  and built many paint booths over the years, I have
developed an excellent design for one offs and "back-yard" types.  While
still using a used furnace motor and fan. The principle is very easy, DON'T
draw out the overspray and fumes, rather "blow" them out. It's a positive
pressure design. I will try to post some pics this weekend. I mount the fan
inside a box with two HEPA furnace filters on the sides. This is mounted to
the ceiling and outside wall of the paint booth and blow air into a wooden
plenum, (~ 4' X 8' X 2') that is also mounted on the ceiling but inside the
paint booth. The plenum has cut outs on one face and the bottom for 4
furnace filters. The entire booth is made out of sticks and poly. At the far
end of the booth is my "door" and it has along the bottom edge 3 furnace
filters. For those that are mathematically inclined, the number of filters
"blowing" air into the booth exceeds those "exhausting" out, there for you
get a pressure differential or positive pressure inside the booth vice
ambient air outside. You will have a combination of cross flow and
downdraught at the same time! The real benefit is that the positive pressure
in the booth will not just blow out the exhaust but will serve to blow out
every crack, crevice, joint, etc. in the booth, vice sucking in air, (dirty
unfiltered air) from those same areas. I control the quality of air going in
and the thus have a cleaner safer paint booth. 
  "Sucking" the over spray and fumes out means having a potentially
dangerous situation where the flammable fumes are drawn across an open
electric motor as well as gumming up the fan blades very quickly. Mine is
permanently mounted in a corner of my hanger and has folding walls that
swing out of the way when not in use. Takes 5 minutes to set up when I need,
of course that is not including moving everything out of the way first! LOL!
Over the years this system has served me very well and produced some pretty
darn good work. 

Wayne


I am more than happy to share any knowledge or experience I have with
painting and finishing and leave that up to Larry. I am currently getting
ready to paint my SCCA sports race car and will try to take plenty of
pictures of the process and my home made paint booth. The booth is a pretty
simple design with a down flow (air) idea. The idea is to basically pull air
in from the top and filter exhaust air our of the bottom back side. Its a
simple erector set style idea using ?2 X 3 lumber and polyethylene clear
sheeting, a few dense micron furnace filters to draw air in from the top and
push them out with a squirrel cage fan out of a used furnace to both filter
and exhaust air out of the bottom. ?Its all put together using screws so
that I can take it apart to store in my hanger. I have thought about re
doing it with PVC pipes and PVC elbows to allow putting it together and
taking it apart without using screws. Simply slip it together.?

KR> Weight.

[Wayne Tokarz]

COOL! Thanks guys, some very useful information. I'm a bit of a minimalist,
however, safety, reasonable upgrades and modifications will all add-up. I
will now have to make my list, and live with the results.

My original KR2S weight was 600 pounds at inspection in 2006. I was pretty
happy with that. Probably up to about 625 pounds by now. Max weight is 1100
pounds - that was calculated to keep the C.G. from going aft of the limit -
no other reason. VW Revmaster 2100 engine, just a header tank, no flaps or
belly board. Just basic VFR instruments at 1st flight. Since then I've added
lights, Dynon D6, Transponder, and MGL V6 radio. Over 480 hours flight on it
since 2006.

KR> Weight & Balance

781 lbs! is that  not a bit on the heavy side? What do other planes
"typically" come in at? The spread sheet on the net is a bit dated and not
very complete. Not criticizing, just curious.

The new panel for N891JF is finally coming together.  See
http://www.n56ml.com/n891jf/panel/panel_trial_fit for a trial fit of the big
stuff mounted and almost ready to wire some stuff.  Details are at
http://www.n56ml.com/n891jf/panel .  I'm also working to change the canopy
from side-hinged to front-hinged.  Simple to do, I think.  More to come in
the next few weeks, I hope.  When I'm done I'll have a website that details
how I did all of this stuff...

KR> prop sticking to hub

[Wayne Tokarz]

Sorry about the windshield...but it is done, safety glass cannot be buffed,
polished or anything. A single edge razor, (with care) is very good for
removing stuck or caked on debris from both the windshield and the hub. Care
must be exercised not to scratch anything. Using ANY product that requires a
"sanding motion" will invariably have an abrasive component to it and this
is to be avoided unless you are goal is to use abrasives to accomplish the
task, ie: sanding or polishing, not cleaning. Use a bar of soap and rub a
little on the back of the prop, polish lightly to smooth it out, use your
finger to get a little in the holes or on the drive dogs. Any automotive
paste wax will do the same thing, more IS NOT better.

Scotchbrite pads contain fine particles of steel that will embed themselves
in your wood prop and will scratch your hub. I did not know Scotchbrite pads
contained steel particles. I had just replaced a cracked windshield in my
car and somehow got a real hard substance like sap right in my drivers field
of view. Regular glass cleaner would not get it off and I just happened to
see my box of Scotchbrite pads and grabbed one thinking it would get it off
easily. Well it pretty much did and it also scratched my windshield and now
I have a very annoying spot right in my line of sight. I know this is off KR
now but if anyone knows a remedy to get the scratches out of my new
windshield I would appreciate you letting mme know. Thanks

KR> Brian/ epoxy

[Wayne Tokarz]

Hi guys, I don't say much but here is my two cents worth. Brian, this flying
thing is a serious endeavor and fraught with pitfalls. Best not to cause
yourself more grief than needed. This little bird is a very frugal way to
get some good flying in, but like everything else, has limitations. Certain
epoxies are more sensitive than others to mixing ratios, it is critical to
follow manufactories directions in this respect. You said "Dynel" in one
post. I would very strongly recommend that you re-skin those area as you
will only have trouble over the long period and I don't know of any KRs
still flying with it as it is prone to cracking. When it comes to safety and
doing things right, this group is a pretty amazing bunch and will truly work
hard to help you have the most rewarding experience possible on this
wonderful adventure. I'm working on my second KR and plan to keep it super
simple and super light, like it was intended to be. I currently own/work
on/fly a KR-2, Pietenpol, Barracuda, Emeraude, and a Renegade, well most of
them are wood!
