Thanks for the tips everyone.
I ended up buying a selection of pipes from Aircraft Spruce with approx the
right inside diameter. One of the pipes was a pretty good fit.
I now have the right side tailplane fitting quite well, the front pin is
fully engaged and the back pin is about 2mm (approx 5/64" or .0787") from
being fully engaged.
The left side tailplane is not quite there yet, I have approx 2mm (approx
5/64") gap from the pin being fully engaged at the front and 5mm (approx
13/64" or 0.1969"at the back.
As far as I can tell all four pins are very close to parallel with the
torque tube.
I believe the problem with the right side tailplane to be the position of
the bushing. I'm not sure which of the two bushings to move but I expect
one of them is in the wrong place.
The left side is a bit more complex, I can't see anything stopping the pin
---From fully engaging. My next step is going to be to measure inside the
tailplane to see if the torque tube is hitting something inside the
tailplane. The pip pin holes have not yet been drilled so I can't use that
as a guide.
Any suggestions or critique of the above thoughts would be most welcome.
I've wasted enough time procrastinating over the tailplane fit, I want to
get them installed and move on.
