Bent U/c replaced #64



Rans spares came & were unpacked.
Two months after bending the S4 u/c, we are back up & running, being fortunate to obtain good quality original Rans spares for a 16 year old machine.Down at the hangar we discovered the parts though nicely 'finished' actually needed drilling and reaming in a few places from 3/16" to the correct 1/4". Had to do that first, finishing with an imperial 1/4" parallel reamer.






It was easier to hang the Rans up from the hangar roof on ropes tied to the engine bearer firewall fittings, rather than trestles underneath. This alllowed a clear working space underneath, nor could it slide or topple off. A bit awkward & needed two peoplewhen we had to uncouple the strut bottom pin, as lifting the wing merely rolled the suspended fuselage. But with my knee braced sideways against the longeron and supporting the wing strut at the bottom by hand, Graham removed the bent Ali fuselage mounted channel to put in the new one.
Afterwards we re-laced the fuselage fabric neater than it was before.
