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.  - Rob Wolf
