Hello Pete,
In principle I understand what you are suggesting.
A few years ago, an engineer chap named John Baker here in Oz modified his E
uropa along those lines. On his system, each pin is replaced by two studs. T
here are two separate half round pieces placed within the tube and saddles a
re placed on the outside. The studs then clamp the inner and outer pieces to
gether between which are the inner and outer torque tubes which get very tig
htly clamped.
The only downside I can see is the cost of machining but if done in a produc
tion run I'm sure it could be done quite reasonably.
Regards
Kingsley
