| Subject: | Tool sharing -- aircraft cable tension meter |
With the importance of properly tensioned control cables, would there be any interest
in a "floating" aircraft cable tension meter? The expense of nearly $800
makes it hard to justify for one builder with one plane.
It seems like two options could work.
Option A: Shared purchase/unlimited future use for the cost of one-way shipping
to the next user (by a group of at least 16 builders chipping in $50)
Option B: Rental at $xx (plus one-way shipping to the next user) with one builder
buying and owning the unit.
Any interest out there? If so, please reply with the option that you might be
interested in. If I get at least 16 "Option A" responses, I'll pick one up ASAP.
BTW, I know there are other ways to calibrate our cables. This is just to investigate
how to make a purpose-built quality tool available to the broader group.
I've attached the instructions for the Tensitron ACM-100 from Aircraft Spruce.
Thanks.

Subject: Mid top pucker, gold oil top cover
All-
Back to Zenith Construction Problemsolving 101. Applying siding is
child's play compared to working on the project!
1. My gold oil top cover came from WW and subsequently I just had to
tear the rear accessory cover and pulley back off. The gold oil top
cover is an essential part if you're not using a remote oil system. What
isn't evident until you actually get the cover is that there is a
bushing that has to be pressed out of the factory rear cover to allow
you to install it. The advantages of the gold oil cover are the ability
to use an integral oil filter and ports for the oil temp and pressure
senders. Check into this before you start bolting things together.
2. My first thought re: mid skin pucker was to lap the side skins
over the mid skin. Larry Mac talked me out of it, because this is an
opportunity for water to enter the inner airframe.
Perhaps a better way of approaching the problem was suggested by
Jeff Small. "Spoon" a little bit of curvature into the junction area.
Good building. (I hope I actually get some in!!)

I like the idea ... but I wonder how this is used after the cables are
installed in the aircraft, which is when the measurement really needs to be
made?
There are also some less expensive alternatives out there, such as:
http://www.aircraftspruce.com/catalog/topages/cablegauge.php.
Wicks also has a cable tension gauge for $89.99 in the last of their catalogs
I got. I suspect the difference in price is ease of use, and accuracy. If it
is only going to be used a few times, then ease of use is not quite as
important as it might be. And, how accurate must it really be?

The picture on Larry's site showing the gauge with the bucket hanging on the
cable just shows the calibration procedure. As Larry said in another message
"I built one that is real simple and have used it off and on for 4 years."
So I believe he is using it to check cables in the plane.
I looked at the one on the Wicks site. The design is very similar to Larry's
home-made gauge. But it doesn't seem to go low enough for the cables in the
Zenith planes:
http://www.wicksaircraft.com/catalog/product_cat.php/subid=1814/index.html
"Ranges 3/32: 70-300lbs, 1/8: 100-500 lbs. 5/32: 140-800 lbs. Fits cable
sizes 3/32, 1/8, 5/32."
The Burroughs gauges in the Spruce catalog appear to be sensitive enough:
"Tension range: 10-70lbs. for 1/16" cable, 15 - 70 lbs. for 3/32 & 1/8"
cable. 50-350 lbs. on 5/32" & 3/16" cable."
You can always check the accuracy of the cheaper commercial gauges using the
same approach shown on Larry's web site.

I think you're correct about the range of the Wicks gauge. I'd be curious to
know how Larry uses his gauge with the cables installed.

I think his gauge simply clips over the cables and indicates tension after
calibrating on the cable stretched by the weight in the bucket via the bell
crank. I don't think the entire setup in the photos is the gauge - it is si
mply a method to tension a cable with a dead weight. The the gauge spring l
oads across the cable in the A/C.
I wonder if he has one for every diameter cable/cable construction since th
ere is a small effect that is related directly to the cable diameter and co
nstruction?

Hi guys,
The gage is constructed to be placed on an installed cable. The gage is
opened against the spring enough to allow the pulley
geometry to open enough to slip over the cable. The spring pulls on the
leverage and tries to bring the cable around a bend
and closes enough for you to read the pounds marked on the gage. The
preload to mark actual pounds before checking
is direct and very reliable. The only difficulty was finding a spring
that had the stretch and range to retain its shape.
It was music wire of .025 diameter outside diameter .275 diameter and
approximately 1.62 inches long.

The geometry of the two halves and wheels are best seen in the links above.

Now it makes sense. Thanks for the photos and explanation. It sounds as though
Mr. Downey's understanding is correct.
