What I need to know is, do I need one on the bottom as well? If it's just
for looks only, I'll go on top>>
Hi Jimmy,
It definitely is not `for looks only` it is for efficiency. The tape should
go from the top surface of the wing to the underside of the aileron.
On the other hand I have seen gliders, who REALLY worry about things like
that and fit ailerons/elevaters/rudder to much tighter tolerances than a
Kolb, use a tape to connect both TOP surfaces. Might be worth talking to a
glider pilot who is current about it. My gliding experience is many years
out of date.
Cheers
Pat

>>>>>>>>>>>>>>>>>
i did mine the way pat describes... but i used book binding tape,
found an exact match,,, used 2 inch wide tape, overlalped sticky side
to stick side 1 inch,,, leaving 1 inch sticky to attach to the top of
wind and 1 inch sticky to attach to bottom of aileron. i guess you
could do it with polly fiber,,, but not 100 % sure how to keep a
straight line when gluing the inside line on the strip. maybe you could
use some type of silicone tape.

Subject: | New Dremel accessory |
A couple of months ago I was in Lowe's when I remembered I needed a package
of cut off wheels for my Dremel. At the display I found they have a new cut
off wheel and drive mandrel out. The old ones were fragile and used a single
screw to attach the wheel to the mandrel. The new one uses a spring loaded
collar on the mandrel with a positive drive key to engage the wheel. The
whole thing is just plain slick. The new cut off wheels last 3 to 4 times as
long as the old ones even going through alloy steel. I cut the heads off two
AN 5 bolts and the wheel only lost an 1/8" off its diameter. If you go to
Lowe's look carefully I found the mandrel and five wheels as a special for
$15. Separately they're about $18.
Just to keep this specifically Kolb related, I was removing the elevator
hinge from the horizontal stabilizer of a Mk IIIX yesterday. The original
builder did a poor job of drilling the holes and every one of the stainless
steel pop rivets spun before the drill separated the head from the body. I
used the edge of the new Dremel cut off wheel to shave the head head of the
rivet until I could just see the line concentric to the center hole. A light
tap with a punch and the rivet was removed with no more damage to the hole.
I did all 48 rivets in about a half hour and moved on. The cutoff wheel
barely showed any wear.

is 99% dead now!! It won't stay running for more than a few seconds=2C may
be the

te=2C I want a new
cut-off tool. Since I just had a birthday a couple of days ago=2C I decide

Since you recommend { finally : ) } the Dremel=2C and especially the new

I'll head over and check them out!!
Thanks=2C Rick BTW=2C are you referring to those fiber reinforced cut-o

There's no doubt I demand a lot from my tools. Probably a lot more than
they
were originally intended to put out. I guess my approach is=3B if this too
l can't
get the job done=2C then "I'll get the next bigger model!!"
I haven't tried the Marvel oil maintenance....but I will from now on. Da
rn
sure couldn't hurt.
I kinda think my present Ryobi is toast=2C but what the heck=2C right now
it's like an
old 'straight six' running on 4 cylinders. I'll see if a little oil will h
elp....
I did find on eBay that neat=2C new mandrel Rick was talking about. It h
as a
kind of butterfly hole in the disk=2C that spins and locks into the mandrel
head.
Nice feature.
MY problem is: I liked the Ryobi because it had about 8-10 speeds. I don
't
think the Dremel does. I'd miss that feature.
In the last year=2C I burned up two hand-held grinders!! My old faithful
Makita=2C
and it's replacement Milwaukie. I'll be a little easier on my brand new Mi
lwaukie.
Plus=2C from now on=2C I'll use some Marvel oil once in awhile...

Mike, The old cut off wheels I was referring to are the fiber reinforced
ones with a 1/16" center hole for mounting. They were just too fragile for
most anything and if you pushed them too hard the center cracked out and you
were done.
As you can see the new ones are much more robust.

- Mike- I don't think you can lube the electric tools.- Maybe a drop on
the bearings.- If you use a Dremel for end grinding, like pushing straig
ht in, the main shaft gets set back.- My battery powered Dremel did that-
my fault.- I was able to disassemble and push the shaft back into positi
on.- John was talking about the air powered ones.- If you have a compre
ssor, get the 1/4" drive tools.- By name brand ones, like Ingersoll or Ch
icago Pneumatic, or Snap-on.- Craftsman used to make a 1/4" drive electri
c die grinder- 110V.

Hi Rick=2C
The disks that I was referring to were fragile=2C unreinforced kind.
If you breathed on them hard=2C they broke!! Pretty near useless=2C IMO=2C
unless you were cutting balsa wood....slowly!!
The 'much better' ones I was referring to are the fiber reinforced ones.
I generally got lots of mileage out of these....that is=2C unless I bumped
them sideways=2C or layed the tool down too hard. I have bent in half
dozens of these. Yes=2C they do have the rediculously little 1/16" hole!!
I haven't seen the new cut-off discs you're referring to. I'll make it a
point to check them out.
As I previously stated=2C I really liked the Ryobi rotary tool. But=2C I
'm open to
recommendations regarding the Dremel. Does anyone have a "preferred
model" they like.....and why?

House completion=2C odds and ends=2C freezin' cold shop=2C and all kinds
of other
poor excuses!!! I could turn the heat-pump on in my shop=2C but I found ou

gets a little expensive.
Add on top of all that=2C 3 weeks ago today I hurt my upper back while wo
rking
on my storm cellar. I can't carry those 100 pound bags of mortar like I us
ed
to. I've had a pinched nerve and nagging headache every day since!! Ya ca
n't
get much done when you're 'uh hurtin'".
By the way=2C a progress update=3B I installed my front instrument panel
/radio
console a couple of days ago. I had a couple of minor antenna cable issues
=2C
but I got those all resolved today.
Just for s & giggles=2C I made a little wind tunnel for the pitot system
=2C prior
to carrying the panel over to the shop. (I borrowed my wife's hair dryer
=2C
which surprisingly=2C worked VERY well. I taped up the 'heat' button=2C so
it
blew only cold air)
Here's what I found out=3B
The Dynon D10A EFIS and the UMA airspeed indicator were virtually exact
in their respective readings. In fact=2C it surprised me how much they rea
d the same.
One thing=2C though. The UMA airspeed indicator was "not as precise". I
t seemed to lag
about 2-3 mph. This trait did NOT appear to be a safety problem=2C just
a little annoying that it wasn't as gnat's-ass accurate as the Dynon. The
Dynon
was phenomenally sensitive to the slightest change in air pressure. I get
the
impression it is accurate to less than 1 mph=2C whereas I would give the UM
A
an accuracy of about 2 mph. Either one of them would be plenty qualified
to be a primary source of airspeed information=2C it's just that the Dynon
was soooo much more precise!! (What would you expect for the $$?
Remember the "you get what you pay for" adage?)
I was very surprised to find out that they both coincided in their readin
g so well.
I feel a lot more confident that I have (at least one) excellent=2C trust
worthy
airspeed indicator!! Before my little wind tunnel test=2C I did not know t
his!!
For the record=2C I wasn't trying to establish that either one of the air
speed indicators
was "exact" in their accuracy=2C but rather=2C that they=2C in fact=2C work
ed at all!! I do NOT
want to get myself in a situation where I ASSUMED everything will work prop
erly=2C
just because I want them to!! I'm a firm believer in 'trust=2C yet verify!
!'
I look forward to warmer weather. Can't get much done in this kind of
cold temps.
I think I should be able to fire up the engine in a couple of weeks=2C or
so. Now=2C THAT

Mike W/Kolbers:
The UMA may turn out to be a better ASI than the one you spent all that
money on, the Dynon. I don't know that.
However, the UMA lags, am guessing you mean it does not change indication
instantly, because it has a built in dampner to prevent the needle from
bouncing around at every tiny, minute bit of disturbed air, air pressure,
etc. Without the dampner the needle would probably be a blur.
Just guess, of course.
To me the most important aspect of the ASI is that it will indicate to me
where my stall speed is so I can stay above it.
ASI's are very reliable. Usually alway work well enough to establish stall
speed, unless one forgets to take off the pitot cover, a dirt dauber or
spider takes up residence in the pitot tube, or someone blows into the pitot
tube to see if the ASI really works.

Hi John=2C
The UMA being the better indicator=2C naw=2C I don't think so. It's hard
to
describe very accurately=2C but the Dynon airspeed readings were smooth.
With the pitot inlet propped up in place=2C directly inline with the airstr
eam=2C
I could vary the airspeed readings by adjusting the distance from the pitot
opening
from the hair dryer flow of air. I could get a reading of about 60 mph
max @ 1"=2C or as little as 10-15mph @ about 12".
So=2C with both units reading....let's say 50 mph. If I don't move anyth
ing=2C they
both continue to read the same airspeed fairly well. They also both seem t
o agree
closely=2C almost all the time. Any disparity was never more than 3 mph.
Now=2C if I stick my finger in the airsteam just a bit=2C the Dynon will
reflect a
modest decrease=2C 1=2C 2=2C maybe even 3 mph=2C but the UMA...no change.
If
I remove my finger out of the flow of air=2C the Dynon goes back to 50. In
the
meantime=2C the UMA never left 50.
Would a more expensive pitot style airspeed indicator have performed bett
er?
Absolutely!! There is a reason why they cost several hundreds=2C and this
UMA
only costs $169. I've heard it said=2C you get what you pay for.

BTW=2C it wasn't such that the UMA 'lagged'. With small airspeed changes
=2C it
didn't lag=2C it just didn't change at all!! If the airspeed pitot pressur
e exceeded 4-5mph=2C
then the needle would move.
I am not knocking the UMA. It has shown it performs plenty good enough t
o
provide accurate (enough) airspeed readings. But=2C I am convinced a much
more expensive unit would be 'more sensitive'=2C that's all.
> To me the most important aspect of the ASI is that it will indicate to me
> where my stall speed is so I can stay above it.
I couldn't agree more!!!!! As was previously established in an earlier t
hread=2C
regardless of whether your airspeed indicator says 40 or 400=2C (at stall)
THAT'S
the magic number to stay above!!
> ASI's are very reliable. Usually alway work well enough to establish stal
l

That's what I wanted to establish=2C namely=2C that these things simply w
ork!! By all
accounts=2C they seem to be functioning quite well. This fact is all I was
counting
on! Whatever reading they say at stall=2C that will be the 'magic number'
to stay
much higher than.
