Hello all,
My Europa has developed some play in the outer aileron hinges as a
number of people seem to have experienced. I am planning to replace the
hinge wire with a teflon sleeve but have not been able to find a
consensus about the right size from previous emails. Recommendations
copied below are for sleeve of ID 0.066", wall 0.012", OD 0.090 (with
pin 0.0625) or ID of 0.105, OD of 0.125, wall thickness of 0.010 with a
pin of 0.094. That seems quite a big difference.
My hinge wire for the standard Europa supplied MS20001-5 hinges is 0.092
inches, so the second suggestion sounds closer, but I'm not sure whether
the OD of 0.125 would go into the hinge. ACS specifies 0.089 inch pin
for MS20001 hinges.
I would be very grateful if those who have successfully used teflon
sleeve in the standard MS20001 hinges could tell me the dimensions of
the sleeve and hinge wire used, and where they were sourced from.

---From McMasterCarr:
teflon sleeve: 5335K17, ID 0.066" (1.6764 mm), wall 0.012", OD 0.090"
(2.286 mm), $2.30 per 10 feet
pin: 7972A261, 1/16" (1.5875 mm), $17.60 forr 32 lengths of 3 feet
McMasterCarr does not ship overseas anymore so a US builder might
intermediate.
The diameters are smaller than the ones you mention Graham, but more
likely to be correct?
Could it be that you have larger hinges than MS20001?
I measure hinge ID of MS20001 at about 1.8 or 1.9 mm, regular pin OD at
about 1.5 or 1.6 mm.
Inserting the teflon sleeve proposed above will be a stretch already. A
question also arises concerning the pin proposed above - diameter
seems rather similar to that of the regular pin.
