Control Column Question
Posted: Fri Feb 17, 2012 9:38 pm
Hi everyone,
I just finished putting the control column together on my SR. What a pain.
Was there a better way than using hemostats and needle nose pliers to get
the bolt through the control stick fittings, tangs on the aileron control
cable, and the aileron push rod end fittings, and eventually the nut on the
bolt? There sure isn't much room for the nut. I also had a hard time
jambing a wrench in there to tighten the nut. To keep it from rubbing on
the inside of the control tube I ended up using one washer on one of the
bolt heads for the right control stick fitting and two washers on the other
bolt head for the left control stick fitting. The welded on tangs that
stick up from the control tube were not exactly in line with each other. I
had to bend the right one a bit and use the extra washer to keep the nut
from rubbing on the inside of the control tube. Does all of this sound
familiar to anyone else or did I do something wrong? Will there be a danger
of the nut hanging up on the control tube when elevator pressure is applied?
Also, I was surprised at the friction in the system since the control stick
fittings are merely bolted between the welded on tangs sticking up from the
control tube. I stuck a three foot long piece of wood in a control stick
fitting and the friction is hardly noticeable way up there but I wonder if
the ailerons will self center in flight or if there might be too much
friction. I purposely did not crank down on the bolts through the fittings.
I just made sure the nut was seated on the washer and that the bolt was
through the nylon insert.
