Possums,
I see you do not have the tabs with the different holes in them like comes with
the MK III, did you put a turnbuckle in there somewhere ? Looks like the lengths
would have to be perfect to keep the tail from twisting, was that difficult
to set up ? BTW, Nice shop ! I need a work area like that, I would be
motivated to get a lot more done...

Subject: Kolb-List: Electrical question - shielding
Here's the problem. I am using a fuel gauge that is connected to
capacitance type probes. When the engine is running, (503 DCDI) the
fuel gauge jumps around like crazy. After much testing and trouble
shooting, I believe the problem is related to the fuel sender wires
running near the ignition kill wires and/or the tach wire. When I move
part of the fuel sender wires a few inches away, the problem improves.
I'm really not wanting to move the sender wires to the other side of the
airplane to give more space between the different wire types. Before I
do this (since it would be a lot of work for a fix that's not 100%
guaranteed), is there a quick and easy way to shield the fuel sender
wires? Would this even work? Any help from the electricians in the
group would be appreciated.
Michael,I used shielded two conductor 18 Belden for kill switch wires on
my 503 powered Loehle, and 2SI powered Mk-3.Only connect the engine side
shield wire to ground and trim the switch end shield wire even with the
jacket.This should clear up your noise.Denny Rowe

Hi Will,
Indeed I do. I also remember what I did with it next. I drove it into a
barn and had to start all over again. Luckily the 50% rule doesn`t apply

Better luck

Jack,
That looks like a good solution.
I have a suggestion based on a problem we encountered on our Allegro. We
used a couple SS clamps similar to those shown in your photo, to help
stabilize the muffler which had a tendency to vibrate a lot and crack.
Inadvertently, we had one of the clamps making a relatively sharp bend (like
your 90 degree bend at the bottom of your battery) where the screw thread
slits were located. With the higher stresses at the corner and the weaker
part of the clamp, it broke. When we installed the replacement we positioned
it so that the weak part was not at the higher stress area and had no
problems since then.

You can change those things to.
Not that there is anything wrong with the original equipment.
It's just cleaner and not that expensive to do.
I had all my cables "machine" swaged this way ( elevator, rudder and
tail wires)
by a guy near Aircraft Spruce in Griffin Ga.
He supplies the cables and fittings.
He does need to know the length from "hole to hole" on the attachment
points and they are only adjustable about an inch.
There is only a turnbuckle on one end so you better know the measurements
if he's not local.
I'm sure there are people like him all over the country.

| Subject: | Re: Electrical question - shielding |
Thanks Denny.
I was wondering if shielding the fuel sender wire would work instead of
shielding the ignition wire and if so, what can be purchased to shield
it?
I don't want to mess with any other wires since I don't have any
problems with radio noise. I just need a little distance between the
sender wire and the other wires that are bundled and running down the
side of the frame to the instrument panel. The tach wire might be the
culprit as well so I would really just like to shield the sender wire
without replacing any wires or moving anything around.
Is there shielding that can be purchased (or made) and slipped over the
existing wire? The wire currently runs along with all the other wires
in a bundle which is doesn't like, but this makes for a cleaner
installation than having wires running up both sides of the fuselage.
If the shielding won't work, then this will be my next step. Moving
half the wire away from the bundle by about 2 inches made the problem
improve by at least 40%. The capacitance system must be very sensitive
to other electrical fields.

McMaster-Carr has what you need. Go to their website and search for part number:
This stuff is a little spendy, but works great.
7940K31
Emi/RFI-Shield Polyurethane Wraparound Sleeve 3/8" ID, Up to 3/8" Bundle Dia
In stock
Quantity Per Ft.
1-24 Ft. $7.00
25 or more 5.50
If the above is too expensive, do a search for braided sleeving. They have several
diameters of tinned copper braid. Some of the ultralight places sell similar
wire braid for shielding spark plug wires.

If you are frugal like me...then rescue some RG-8 coax from the
salvage yard and pull the braided shield..Easy enough since it
expands when collapsed...most of the connectors would have to be
removed from the wire bundle... however....Herb

-58 is 50 ohm. -59 & -6 are 75 ohm.
It should be noted that most, if not all rg-58 has a solid center
conductor. If it's installed where it doesn't move at all, it will
probably outlast you & the plane. However, if you're plugging &
unplugging from a hand-held & hang the dipole end so it can flex & move
as the plane moves, you might have problems with the center conductor
either breaking or pushing its way through the foam center insulation &
touching the shield. There are other 50 ohm coaxes that have a stranded
center conductor so they are more flexible.

Jimmy,
Thanks for the pictures!! I may never get to fly over your part of the
country, but at least I can get some idea from your pictures what it
looks like. I enjoy the beautiful countryside here Lancaster county,
PA, but my little FireFly isn't up to the long distances required to
reach your part of the country. Or maybe (probably) it's me that isn't
quite up to the challenge.
Again, thank you for posting the pic's,
