Gents,

How about a noble group of smart builders using their collective brilliance
to help put together a simple canopy locking mechanism.  One with only a
single torsion tube and something like an eccentric on each end and NO
levers or rod ends.  One that weighs about half of the $400 job at Lancair
and can be fabricated with stuff already on the shelf.  I'm about there with
it but have a stumbling point at the eccentric end pieces.  Maybe eccentric
is not the way to go but it does seem to fit some of our building
practices.  Pun intended.  It should be accessible from both in and outside of the airplane, lockable
with a key at the end of the day, simple bearings made with bids, torsion
tubes flush with the outside skin yet pulled out with thumb notches and the
pulled out part useable as a handle to unlock an over center eccentric/cam. It should be capable of disassembly to repair worn parts.  Disassembly
should allow tubes to be taken out the outside skin holes.  I do appreciate the genius of this group when it comes to a discussion of
noble people gassing about nobel gasses.  How about some gassing on the
canopy locking possibilities from our collective brain archives.

Thanks
