rebel upgrades

[alan.thompson]

On a recent message posted by Michael Jones (#007), a list of recommended fixes included
mention of a new fix for the elevators as per Wayne O'Shea. Perhaps I should have
directed this message personally to you, Wayne. I'm just starting the elevators right now
and am interested in the details of said fix, and could not find mention in the archives. Is
there a posting somewhere that best describes this and other rebel mods in more detail?
Any information on this subject would be greatly welcomed by yours truly.
Thanks in advance.
Alan

Alan,

On the site under Files, Rebel, Modifications, there is a spreadsheet
listing various mods with comments. Latest edition file name appears to
be RebModTable R3.xls.

Hi Alan

This is in the archives a few times (although I don't know what keywords
to search for) but concerns the outboard ends of the elevators only as
they have the counterweights in the tips. Those weights bouncing up and
down tend to cause the outboard rib to rotate a bit around the single
rivet that attaches it to the spar. The suggested solution is an angle
bracket on the other side of the rib so that the rib has two flanges
against the rib and two rivets and therefore can't rotate.

In addition two pie shaped skin doublers (top and bottom) under the skin
at the outboard end of the spar is suggested. They would pick up a few
of the rivets into both the spar and the rib. It is this area where some
skin cracks have appeared but I think the real root cause should
probably be fixed with the bracket mentioned above.

I usually don't post" thank you's" for fear of clogging the system, but it's a slow weekend
on the list.
Thanks Ron & Ken.

Thanks Ken! Exactly...saves me some typing so I can now get out and shovel
9+ inches of wet snow and get the plow back on the truck. Winters back with
a vengence!

Hi Ken and Wayne,

Went to the archives and pulled up the elevator mods which brouight a few
questions to mind.

(A) The archive photo of the fabricated angle bracket flange you mentioned
in your email below Ken, seems to overlay the flange of the rib that comes
with the kit rather than on the other side of the rib? Or am I reading the
photo wrong? Would that particular mod/configuration be as good as you
suggested to keep the rib from rotating Ken?

(B) Would the pie shaped doublers, and fabricated flange, result in the use
of rivets different from those the manual specifies be used to attach the
elevator skin to the spar and ribs??

(C) Pie shaped doubler same thickness as the elevator skin?

Many thanx for any feedback you care to offer

a. brace would be best on other side of rib as you mention, if elevator
already built this fix is better than taking elevator apart, another fix
would be to have the bracket with a y shape so it rives to tube in two new
locations and then the rib, this would really stop the problem, more work to
do this but if your building now i think its best solution

b. use same rivets rv1410, i think

c. doubler same thickness .020 i think
