I have a question about the fiberglass end-caps for the elevator.  The
thickness of the fiberglass at the trailing edge of the cap is significantly
thicker than the trailing edge of the elevator where they meet up.  Is it
OK, or even desirable, to sand down the fiberglass so the trailing edge
matches?  Or will this make the fiberglass cap too thin and weak?

Thanks,

Bob Smith

I had a similar question, although in the other direction - I 
ended up with the trailing edge of my aileron (same 
construction process) thicker than I'd expected.  The advice I 
received from the group was that it made little or no 
difference.  I think you can assume the same for the fiberglass 
tip of the elevator.  You'll probably do more harm than good 
reducing its thickness.

Best of luck ...

Bob

I had the same problem with mine.  One of them was over 1/4" thick at the
end and the other about 1/4".  They looked really ugly.  Also, the fit was
not good - they were somewhat twisted.

I used a dremel cut-off wheel  (you could use a hack saw) to open up the
trailing edge.  I followed up the joint line about 4" and kept removing
material until the trailing edge was an acceptable thickness - about 1/8".
I used a structural adhesive compatable with fibreglass (Proform Structural
Adhesive #PF704, flexible plastic repair kit - works well on FG) and
rebonded the opened up joint.  Make sure that there is no twist when
rebonding.  I also used the Proform to fill some nasty blemishes on the
elevator tips.

Don't sand the outside of the fibreglass, because the outside is gelcoat,
which gives you a nice smooth finish.

Hope this helps.
