Delrin aileron torque tube bushings
Posted: Fri Feb 17, 2012 8:38 pm
How much radial play is acceptable between the 2" diameter torque tube and
the delrin bearing? The manual says lightly sand out the bearing to a free
fit. Actually, I had the fit after sanding the bearings and only then
discovering the tight fit was caused by an out of round tube. Having now
corrected the out of round tube, there is now 1/32 radial play between the
tube and bearing. Realizing that sloppy control will result from tolerance
accumulation I will replace the bearings if 1/32 is deemed excessive.
Opinions please.
Happy New Year to all from
