Hi Jeff

What we did with our Elite was dimple the rib and the reinforcement plate and countersink
the lead weight.

To dimple the sheet metal I used a piece of 1"+ thick bar stock, drilled through and then
countersunk that to a diameter just slightly larger than the head of the screw, this
allows for the thickness of the sheet metal. To make the dimple, just put the screw
through the sheet metal and into the countersunk hole in the bar stock and put the works
in a vise and squeeze the head of the screw into the sheet metal, it works like a charm!

To avoid marring the finish of the rib & reinforcement plate I used another block of
metal between the vise jaws and the screw head, this also will help smooth out any waves
that the dimplng may create. Make both pieces of bar stock at least 1" all around the
screws to make sure that any localised waves are clamped & smoothed out.

You will probably want to experiment on some scrap but it won't take long to figure out
how to do a great job of it.

Good luck!

Dave R.

A question about the c.s. machine screws used to
mount the elevator tip weights. How to you get
them to seat flush against the tip ribs. There is
not enough material on the backing plate to
sountersink. I thought that maybe countersinking
the lead weight itself and then letting the
tightening screw dimple rib and backing plate.
Or should I just lighten up?!

Many thanks,

Dear Dave,

Many thanks for providing such a clear
explanation. I am climbing the front of the
learning curve, so the questions are rather
obvious ones, I guess.

Wish I were in Nova Scotia today. I have been
wondering how Elites and Rebels will fly at 6000
ft and 95 degrees.

Hi Jeff

Good to see that there are more Elites in progress so we have more of a group to share things
that are Elite specific. We have run across a few of the "fun" things on the learning curve as
we have one of the very first Elites (583) although it won't be one of the first to fly since we
are fairly distracted by things like work...............

My pleasure to be able to pass on some of what I have learned on our project, the questions are
only obvious when you have the answers! I just crossed another of those hurdles last night
fitting the landing light bracket in the wing, just another common sense thing but sometimes you
have to use the instructions as a guide and think about what you are trying to achieve!

By your comments you must be located somewhat further south than us, what part of the world are
you located in? FYI we were only up to 89F here yesterday although it was unusually warm!
