I had an issue with my cs07's being non-concentric, which i discovered after
making the cs06 captive, with the sticks binding at extremes of travel. The
runout
did seem to be about the same on both. If yours is excessively free, maybe you
could reach a compromise by deliberately mis-aligning the bearing very very
slightly,
which is basically the reverse of what I did to free mine up.

Subject: Europa-List: rear bearing play problem
I would like some advice.
I am at the end of Ch 13 where the aileron drives have been installed on
the bottom of the cockpit module including cross tube and sticks.
I find I have a problem. When exercising a stick sideways while holding
the cross tube there is play in the corresponding rear bearing - tufnol
CS06 and CS07 aluminium flange. Port side worst. Bang - bang - bang. I
think there is about 10 mils (0.25 mm) room. The bearings.are not
greased/oiled yet and I can actually see light through the crack. When
one holds the cross tube the resulting play at the top of the port stick
is about 0.5 mm (arm roughly doubled). It seems like a little but I fear
this will be annoying in operation.
I'm not looking forward to replacing the tufnol parts. Removing the CS07
---From the steel tube undamaged will be essential if I want to keep all
the rest of the setup.
If I have to then heating the tube from the inside with a halogen bulb
may work best
Another question is whether replacement CS06 from Europa will be a
better fit (I don't remember doing anything to the insides of the
offending ones).
ACS has 1/2" micarta if necessary.
Any thoughts very welcome.
