Stab Repair "Help"

[Larry Diamond]

Jim,

I finally got the nerve to try this...Only took me 3 days to convince myself
that this was the best way.

I was surprised at how well it worked. There were a couple of spots that the
wire decided to go off on its own, but Lisa helped to keep an eye on it. We
glued it back last night and now I will need to do some fill work in the
gaps.

I will look again at the balsa on the fuse, but it looked pretty good except
for where the wire decided to depart from the intended cut line.

I think we are in better shape than it was. It's about as straight as I'm
going to get with out a jig, meaning the left side is high by about 1/4
degree if my calibrated eye is correct...lol. Every thing else is perfect in
measuring stab center and distance to the wing tips. It was actually off
about 3 to 5 degrees before so this gave me a reason to make it better...

Thanks,

Larry

 One other thought. I have seen the fuse have longitudinal cracks in the
balsa at the stab line.Cracks with the grain. Check this. you may have to
strip a little covering and soak the cracks with CA
 The wing alignment was meant to say that the wing and stab are parallel as
viewed from the front or rear.

>  I just did this repair on a friends Focus 1. Cut 2 1/2 in dowels about 4
inches long. These are going to be the handles. Take some wire rope better
known as pull-pull cable and stick it through the fuse at the stab line,now
attach the dowels about 2 ft apart to the cable. You have just made your saw
that will cut through the epoxy at the stab glue line. Have someone hold the
plane for you so you can saw.. Just make sure you saw lenghwise to the
stab(left and right) applying enough pressure to make the rope cut  Cut all
the way around,top and bottom. Now the stab will move 1/2 inch left and
right through the fuse. Clean off old glue(epoxy),realign the stab tips to
the wing tips and align stab and wing front to rear. Reglue and you are
done.This all takes less than 1 hour.  Good luck
