Section 23: Aileron Actuation (10 hours)

I finally reordered the aileron control tubes and redid them. This time I did a MUCH better job. This is what i learned:

1. Everything up to the point of primering the insides of the tubes is pretty straight-forward. I still can't seem to drill straight with the drill-press - did my best.

2. Primering. The best technique was as follows:

a. Heating up the control tube to get the fittings off of each end is a must sometimes.

b. After deburring holes, clean by soaking a paper towel in acetone and pushing thru the tube with a dowel.

c. Put one fitting on one end. This will be the cap for this end of the tube.

d. Tape over all the drilled holes, so that paint won't leak all over the place.

e. Pour paint into the other end, liberally. Cover end with just a paper towel and swirl the paint around for even coverage.

f. Then just pour the left over paint.

g. Also, it's good to get this set up ahead of time. Hang the tube with open end down, so the rest of the paint can dribble out the end into a cup or whatever.

Section 23: Aileron Actuation (10 hours)

Cut all the tubes and primed them inside and out.

At first, i could not find the steel aileron collar tubes. I thought i was missing them and even asked for it to be resent by Van's. However, i was looking for a powder coated part, when in fact, it's raw steel. It was actually used as a hinge holder when shipped, which made me think it was just scrap and not a real part. Also, it was not even labelled.

Priming the torque collars was best done by pouring some primer into a ziploc freezer bag, then dunking the tube into the bag.

I screwed up the aileron control tubes. Instead of measuring for 21 11/32, I measured them to 21 11/16, accidentally. Crap. Screwed - need to redo it later. For now, I cut these down to the right size and just temporarily fit the fittings on for now.

A GREAT tip for fitting the fittings onto the ends, is to use a heat gun to heat up the tube to expand the metal. Makes inserting fittings into the ends, even with primer, easy.
