Just my 1 cent on the torque tube issue - whenever I drilled my tube -
sure enough I di not yet have a drill-press - and ended up with too big
holes.
Found rescue in tapered pins and have been flying 9 years now without
any issue or the need to re-tighten them.
See everybody at Copperstate this weekend !

just a note until I get what's left of my brain back in gear. Just
back
---From Hungary having my teeth fixed, they pushed the price so high in
UK
they don't get the practice , the Hungarian guy was very
professioanal
and good value.
I don't like the idea of taper pins, there's too much possobo;ity to
pull the torque tube oval and that will ruin the behaviour of the
bearing bushes. It would be possible using a machined plug to resist
the
compression but not as simple as it first appears
