You are correct Andrew, as the spring compresses and the A arm swings towar
ds the fuselage, the angle on the bolt tubes changes.- I was able to cons
truct mine to minimize the binding at these locations.- It is only at the
extreme end of travel, where the spring is almost fully compressed, that t
here is any sign of binding.- In my mind, it is not going to be an issue,
considering how often the gear gets compressed to that extreme.

I installed bronze bushings in the 2 a-arm attach-fittings (The ones bolt
ed to the lower longeron).- I seem to have to change them almost once a y
ear.- The holes in the fuse. fittings were getting sloppy so I figured I'
d better do something so we didn't have to cut off fabric to install new fi
ttings.- They probably wear fast due to flying off of grass almost exclus
ively, and having a very small tailwheel.- What you say makes sense, abou
t the binding, and the angle/ misalignment with compression of the t/w spri
ng assembly.- Mabey in 5-10 years if and when I recover the piet, I will
try to "Improve" some of those types of things, but untill then I will spen
d the $3 per year and put new busings in , and keep flying untill the crank
snaps.

On NX18235 we installed rod end bearings at the A-arm ends.
No binding and no wear.

You are correct Andrew, as the spring compresses and the
A arm swings towards the fuselage, the angle on the bolt tubes changes.
I was able to construct mine to minimize the binding at these locations.
It is only at the extreme end of travel, where the spring is almost
fully compressed, that there is any sign of binding. In my mind, it is
