I just finished this on my LNC2. The aircraft is still in my garage, and the
stub wings have not yet been installed. Total time was 5 hours of hands-on
working time, which took place over 5 calendar days. Could have done it
faster (calendar time) but I had other things to do.
This is probably the only time I have not been envious of you guys that are
already flying.
The job was duck soup to me, because the stub wing was not installed. I
don't envy you guys that are trying to do this on finished airplanes, but it
shouldn't really be that bad. I did not have to break into the landing gear
hydraulic system, but I don't have brake lines in, and these might have to be
disconnected in a flying aircraft.
I made a template of the phenolic brace from some thin plastic I had on hand.
Cardboard would have been fine, too. I then roughed out the phenolic on a
band saw. Final fitting was accomplished with a belt sander. (Yes, the
pieces are different sizes, by about 1/16 inch) Hysol/flox was applied and
allowed to cure at room temperature overnight, which resulted in a tacky
surface since hysol takes so long to cure. I have a small forced air space
heater, smaller than a shoebox, that is controlled by a
far-fancier-than-required thermostat which uses a tape-on thermocouple as a
reference. I set this to 140 degrees F for four hours on each phenolic
brace, after which time the hysol was rock hard. Then came an epoxy-flox
fillet and then the 3-BID, with some excess which was trimmed in the green
cure state and finish sanded (to remove rough edges) with a Dremel.
All in all, it was fairly simple and nothing to be afraid of.
