Hi! Tony and all.
On the rear tufnol bearings I put a tiny hole through (tufnol only!) and
glassed up an aerosol can injection pipe so a can can be inserted on to it
for future blasts of suitable lube. I also drilled the front ones to take
such a tube directly from the can. On the tail plane torque tube fitted
very small grease nipples with tube extensions through the final
alpplication of redux. You need to be very exact though otherwise you will
have the drive plates collide with the nipple.
All I.M.H.O

Gidday again,
My front flight control tufnol block for my flight controls, the one in the
footwell, has an offset centreline of the hole such that about 1/3 of the
way through it wanders. The result is that the metal component slides home
and has a rattling loose fit with about .3-.5mm gap between it and the
tufnol, and that it is obviously not correctly bearing throughout the depth
of the bearing. I worry this tufnol may wear, albeit slowly, such that even
if I take up some of the slack with paint, that in the future it will only
get worse. Does/did anyone else have the same problem?? I am also
interested in the past dialogue about inserting grease nipples for future
lubrication. Is this recommended, or is there a danger of weakening the
tufnol material and possibly splitting it insitu, with the pressure of a
thread in it applying a constant pressure ( I suppose a grease nipple could
be reduxed into it removing any pressures)
In anticipation of ideas
