| Subject: | Mounting the control stick-advice on the nut and bolts |
I have the appropriate Aircraft Spruce ordered AN bolts and nuts, etc.
1. What I am wondering is about the way to assemble them. Do I mount them nut
side up through the floor, or bolt head inside- nut side down... I am using lock
nuts, and where called out, the cotter pin style (I am going from memory as
I have yet to refer back to the plans since restarting the build- but will before
installing).
2. Is a washer enough to keep the lower part of the assembly from digging in and
crushing the bottom of the plywood on the underneath side, or should I weld
either the nuts or heads to a plate so they are tied together somehow.
I am thinking that once I put the fabric on, the heads or nuts will not be accessible
without cutting and repairing the fabric, so whats best? I dont believe
these were called out to be cotter pinned in.
I have the EAA Books, but dont remember if this was addressed.
Thanks for the help.
Mark

Mark, you want to let gravity and slipstream be your friend. Put the bolts
in so that, if the nut were to work free, the bolt wouldn't want to exit
the airplane. That means point bolts down and to the rear, unless you
absolutely have no alternative. Against wood surfaces, place an AN
fender-sized washer between the bolt head and the structure, as well as
between the nut and the structure, in order to spread the loads. Sounds
like you are making good progress. Enjoy, Ken

Yes, Mark!
As for the other part of your question about cotter pins, there's a simple
way to think about what nuts to use. When trying to decide what nut to
use, consider motion and heat. If the nut is attaching any part of a
structure that can rotate, you will need to use a castle nut with a
corresponding cotter pin. If the structure cannot rotate, use a stop nut.
If the structure is aft of the firewall (and therefore not subject to the
possibility of high temperatures), you can use a nylon stop nut. If it
forward of the firewall (and thus subject to even the possibility of high
heat), use an all-metal stop nut.
One additional consideration, still relating to motion, is that if the bolt
can only be stressed in sheer (and in no way will ever see tension), you
can use a low profile stop nut -- again, a nylon version of the stop nut if
aft of the firewall and all-metal if forward of the firewall.
Cheers, Ken

Much appreciated Ken.
I need to fish out the Bingalis books from storage as I am sure my answers
are there, but that might take as long to locate as it will to build the
Piet!
That was very helpful. I do have all of the necessary hardware and have
test fit everything (without actually using the lock nuts- I didn=99t
want to
put them on then take them off a ruining the =9Clocking=9D pote
ntially when I
put them back on), before the project went into a 6 year hibernation.
Now, if o could just jumpstart my memory cells...

Hi Mark, Use wood washers on the bolts through the wood. They are much larger than
the standard small washer used on bolts through metal. Look in the Aircraft
Spruce catalog, I think they are AN-960 but check their catalog. If you use
cotter keys you can put them in bolt head down, or use bolt head up and use self
locking nuts or castle nuts with cotter keys. Jim B
