Whilst cleaning the oil down and covering her up for the unknown time associated with Covid19 epidemic I noticed that a couple of the tail rigging wires didnt seem to have the twang they used to …
The construction has a really neat way of getting these just right in the tail .. using packing washers
You have 8 cables 2 each side top and 2 each side under providing a nice tight geometric taught support for the tail plane
Slight problem is .. there are no turnbuckle.. as this would not only weight but also drag ..
So you make each of the 8 wires to ‘exact’ length with thimble and crimps and use 2-3 washers to pack ..
Once in situ .. you hopefully have it all nice and rigid .. problem is that moving any 1 affects ALL in the setup .. beautifull engineering and geometry.. but a pain 😊
Anyway .. removing 1 washer from 2 and bingo .. the whole setup was making a nice ping noise again when flicked with a finger .. the acid test
