That looks strong, Michael.
What size is the angle aluminum, & wall thickness? I will at least, do that on
the outer rib. Might be a tad overkill for my little 1 seater Firestar.
The picture tells it all.
Thanks Michael

What I meant to say, is it might be a tad overkill to do all the ribs that way.

I've been a machinist and inspector in the aircraft industry for 34 years. I
try never to use heli-coils for the simple reason that you must seat them
before they can be checked to conform to the thread standard for which they
are intended. If you get it wrong they are a bearcat to dig out and re-do. A
much better alternative is Time-Serts (www.timesert.com). Rather than a coil
of shaped wire, Time-Serts are a machined insert with a tapered outer thread
and use a mandrel to lock them into place. How good are they? I've had them
in the short side of my Shovelhead Harley heads (modified for two plugs per
head) for 13 years and they are as solid today as the day I installed them.
Give the folks at Time Sert a call and ask them about your application. If
you decide to use them, I'm sure you will be very pleased with the results.

| Subject: | Weight and Balance Arms for a Stock MKIII |
--> Kolb-List message posted by: "Jason Omelchuck" <jason@trek-tech.com>
I am about to do my weight and balance and don't think my scales will have
the ability to weigh the aircraft with me in it (I know I could use 2 scales
with a board in between). I was wondering if some of you with a stock MKIII
sling seats and stock fuel location could tell me the arm you were able to
measure with scales for the pilot/passenger and the Fuel. Please let me
know if the datum is anything different than the leading edge of the wing.
I did look in the archives and found some arms for the pilot/passenger but
none for the fuel.
Thanks

Big Question??? Does anyone know of a collapsible tap that can be inserted
into the head....

Grounded mk III trying to get ready for MV
>>>>>>>>>>>>>>
Thanks for all that answered on and off the list..... I was able to find a
18 / 1 tap. With shaky hands started to feel my way as I twisted it
into the head... it went in without problems and only required pressure
from my fingers to twist it in and clean out the threads... I removed about
3 or 4 grains of small sand worth of alum. I took the second ell that I
had removed and used it for a trial fit to see if it would work and it
went in and out without problems. As soon as the new part arrives I will
be able to locktite it in place and hopefully be leak free again.
Much relieved

Although not unique in design they look like a good product.
They should, however, employ a better proofreader for their
web page. How do you pronounce" notificition"?

Russ,
You are exactly right. 1mm is 0.03937" and 1/24 = 0.0417" Close enough to
call it 1mm.
What I was trying to say about metric threads is that they are measured by
the "pitch" which is from peak to peak vs American which counts the number
of threads per inch.
Thanks for catching my mistake.
Steven

I'll admit, first off, that I'm pretty new to this list and maybe am getting the
wrong impression on a couple of things. I've followed the Zenith list religiously
for a few years now, and that's my only real basis for comparison.
I hear you guys talking about the various mods you're doing to your airplanes and
I can't help but wonder if they're approved by the engineering types that are
still supporting the various Kolb designs. Or if they're just someone's idea
of a better mousetrap, however well-intentioned they may be. And the uninformed
may grab the idea & run with it, not realizing there's no engineering behind
it at all!
I used to hear the Zenith folks talk about these kinds of mods (changing ribs,
strengthening this or that, etc) in terms of what Chris Heinz (designer) endorsed
.. or didn't. Guess I got used to paying attention to what were "approved
mods" and what were not.
So, do any of the Kolb folks ever get involved in these discussions?
Sorry if I'm being an old curmudgeon. I've just seen a few guys crater after making
some mod or other without a clue as to strength of materials, tension, shear
or any of the other topics from the engineering world. Hate it when that
happens!
You guys wouldn't do that kinda thing, would you?? :-) Hope I'm not talking out
of turn here. For all I know - and I'm still learning - there may be a dozen
Kolb engineers on this list that just aren't identified as such. If so, I'll
be embarrassed ... and much relieved!
Thanks ..
