aileron hinge bushings

[bransom]

I'm at the point of fitting ailerons to wings to check for angle of travel.
I see that the ailerons are supported on 1/4" bolts with 3/8" steel bushings
which insert into the brash bushings of the ailerons.

My question is wrt the materials, as I'm a little surprised to see the steel
bushing. It seems it is a press fit into the aileron brass bushing, and in
fact the brass piece needs to be reamed to get the steel bushins in at all.
So, assuming I do that, what's the corrosion outlook with the naked steel
bushing pressed in there? BTW, the clearance is an easy slip fit for the
1/4" bolt inside the steel bushing, so that is where any lubrication for
aileron control movement would need to be. Seems odd... am I understanding
this correctly or missing something? (odds favor the 2nd possibility.)
Thanks,
-Ben Ransom/ 496R

Yes Ben! Lightly ream the brass bushings so the steel bushing can turn
freely..but not sloppy. Then on final assembly use some light grease and
tighten the bolt so that the steel sleeve is held tightly against the hanger
bracket(s). This way the brass is turning on the steel sleeve for the
largest bearing surface. After that occassional lubrication with LPS1 or
similar will keep them running freely and rust free. Have seen some that got
neglected and rusty...and that's not a good thing!

Thanks Wayne! This makes sense now.
