Dear Listers,
A few Listers have asked me recently, "What's my Contribution used for?",
and that's a valid question. Here are just a few examples of what your
direct List support enables... It provides for the expensive,
business-class, high-speed Internet connection used on the List, insuring
maximum performance and minimal contention when accessing List
services. It pays for the regular system hardware and software upgrades
enabling the highest performance possible for services such as the Archive
Search Engine and List Browser. It pays for 15+ years worth of on line
archive data available for instant random access. And, it offsets the many
hours spent writing, developing, and maintaining the custom applications
that power this List Service such as the List Browse, Search Engine, and
Photoshare.
But most importantly, your List Contribution enables a forum where you and
your peers can communicate freely in an environment that is free from
moderation, censorship, advertising, commercialism, SPAM, and computer
viruses. How many places on the Internet can you make all those statements
about these days? I will venture to say - next to none...
It is YOUR CONTRIBUTION that directly enables these many desirable aspects
of this most valuable List service. Please support it today with your List
Contribution. Its the best investment you can make in your Sport - BAR NONE!

Hi all:
Having just installed my brake fittings and lines and fuel vent fittings,
I'm suddenly faced with a dilemma. How to torque these fittings and how
much to torque them. Note: I checked the archives and found reference to a
web site that supposedly has torque specs etc. but I could NOT get my
browser to open the site. Is there someone out there with the answers that
could email them to the list?
I assume the nylon fittings on the low pressure side of the brake system are
just put in finger tight then turned a certain amount further as plastic
makes a good seal without needing a wrench. I put mine in until there was
some resistance and then turned the fitting to its final position. I did
NOT use a wrench on these, I just turned them until there was a good bit of
resistance to me turning them by hand but was still able to move them using
some muscle. Is there a proper procedure for this? If you tell me to put
it in finger tight please provide the definition of "finger tight"! I'm
afraid I'll brake the fitting if I tighten it so tight that I need a wrench
to turn it. Also should I use any sealer or fuel lube on these? Also what
about the little nylon caps that the nylon lines run through into the nylon
fitting, what procedure and how much should these be tightend? And lastly,
is this nylon lines idea too cheesy? Has anyone had people crawl in their
airplane and put their feet on these fittings and lines and damage them?
Should I scrap the whole thing and use aeroquip flexible or some other such
robust lines?
Same question on the brass elbows used in the brake system. The archives
said to put some fuel lube or sealer on them to prevent leaks. I'm curious
how many people have had leaking problems with these fittings as I found
several folks on the archives mention this? I just tightened the brass
fittings to their desired position after not being able to turn them by hand
any more and I didn't use fuel lube or sealer, should I take them out and
apply sealer? Is there a preferred method for torqueing these things (ie.
Torque wrench and torque specs) or just finger tight then wrenched into
final position?
And lastly what about the AN aluminum elbows, unions etc that we use for
fuel and vent lines. What's the proper method for torqueing these? Do you
use a torque wrench and crow's foot and if so how do you compensate for the
higher lever arm introduced with the crow's foot (or is it so small you
don't bother)? What are the torque specs for these? Note that there are
two issues here: one is the procedure and amount of torque for the FLARE
nuts that clamp the tubing ends to the nipples of the fittings and the other
is the torque and procedure for the regular style NUTS that hold the (union,
elbow, tee, etc) fittings into the bulkheads. Thanks for the info.

Well practiced method...tighten them until they don't leak!! The Van's
recommended setup works just fine with the equipment supplied in the kit.
Personally, I wouldn't waste the time trying to use a crows foot and torque
wrench on fluid fittings, a well calibrated elbow works just perfect!

Hi Guys,
If any of you are at all contemplating purchasing an ELT for your project in
the near future, I just got a flyer form one of my distributors that has
these ELT's at a significant discount. Here's the catch, I have to buy them
3 at a time....
If you're interested, the price will be $165.00+shipping. Everywhere else
I've checked these run $180-190.00+shipping (ACS, Van's, Chief, etc..).
If I can get enough people interested, I'll order some. Just thought I'd
pass along the savings. This is a great ELT, I own two of them now!
Contact me off list if you're interested.
Cheers,
Stein Bruch

I just installed the rudder pedals for the last time (I hope). So..I torqued
the AN3 bolts to 25 inch pounds per spec. This squeezes the plastic bearing
blocks quite a bit and you can see a visible deflection. Should I tighten
bolts holding these plastic bearing blocks to the same torque specs as bolts
holding metal parts together or is there a different procedure? If so what
is the proper way to do this? Also do I need to put a washer between the
head of the bolt and the plastic block? Van's plans don't seem to show any
(just a washer under the nut) but then again when you get this far the RV-6
plans get a little sparse on info and one is left to either guess how things
go or talk to those who've gone before them!
Another question in the same vein concerns bolts holding the aileron and
elevator bellcranks in place. These bellcranks have aluminum spacers
between the structure and washers on either side of the bearing. When I
tried to torque the quarter inch bolt on the elevator bellcrank to the
specified 70 inch pounds, it looked like the bolt was beginning to flex so I
backed it off. What is the proper torque and procedures for tightening
these bolts? I haven't seen any information about how to properly tighten
these assemblies. Thanks.
