Hi Dave, I hope all is well in Kent.
I am still atempting to solve my wobbling about problem. I
changed a rod ball end in the ailerons and various other
things to no avail. The outer hinges on the rim tabs have
some wear. Do you have some of the overside pin available
or would you give me the supplier/part number ?
Do you have a supplier for the whole hinge - MS20001-3 or
is it Europa themselves ?
Thanks
Richard Holder

You can get the hinge from Europa, LAS aerospace or aircraft spruce. I doubt the wear would leave a round hole for an oversized pin. Could try a new pin easily though.

One might consider the “long ez” mod, namely the thinner pin, in a teflon tube/jacket.
Cheers,
Pete

From: Steven A Eberhart
Subject: teflon/stainless hinge pin
I am building a wing section for wind tunnel testing in the University of
Illinois low speed wind tunnel. It is 18" chord by 34" span with a 20%
chord aileron. I used standard aluminum piano hinge for the aileron hinge
and was not satisfied with the amount of play in the new piano hinge
(purchased from Wicks Aircraft). After seeing the posts about the
teflon/stainless hinge pin modification I thought I had found the answer
to the play in my hinge. I ordered the teflon tubing and bought a pound
of stainless welding rod. These are the dimensions of the materials:
original hinge pin .084"
stainless welding rod .061"
dia hole in hinge > .091" could only check with piece of brass tubing
as I don't have a set of drills to verify
diameter.
stainless rod with
teflon sleve .091" but would compress to .084"
The stainless rod easily slid into the teflon sleve and the sleve/rod
assembly easily slid into the hinge. There was still slop in the hinge
after inserting the teflon/stainless rod due to the assembly being able
to compress to .084" but it was a smoother operating hinge. It would
seem that the modification would help prevent new hinges from wearing but
I don't know about using it to repair a worn hinge. Would seem that a
thicker wall teflon tubing would be required. I am on the look out for
such teflon tubing. If anyone finds any please let me know.
A 100 ft. of teflon tubing from McMaster-Carr was $14.00 USD and a pound
of welding rod was $14.00 USD.

Hi
I bought Teflon hinge pin kit designed for Long Ez after some years flying when notice some play (same hinge size as on the Europa)
Address on this page: http://n944x.blogspot.com/2017/05/teflon-hinge-pin-upgrade.html
After 10 years with Teflon/steal no play at all.
Works like a charm.
