My last update (quoted below) seems to have updated on the website but didn't
seem
to email out. I will do this update via the website to see if that is more
reliable.
I've made further progress and now I have both tailplanes fitting quite well,
the
front pin is almost fully engaged (about 0.5mm or 0.02" to go) and the back
pin is about 2mm (approx 5/64" or .0787") from being fully engaged.
Any further suggestions or advice on how to sort out the discrepancy between the
front and back pins would be greatly appreciated.
As a side note, I've discovered that 9.5 degrees C or 49 degrees F is ideal for
fitting the metal parts together. It is proving much easier to install and
remove
the torque tube now than in warmer weather.

pin holes have not yet been drilled so I can't use that as a guide.
