Wotcher wanna DO , is make it PRECISION . either rout a half circle groove in a board & glue in oor holden sandpaper . For the L E , and
use a TUBE with ditto , or a dowel , not a cheap one . So as theyre ' enginered ' for a precise gap .
Cunning Swine use pre chamfered / wedged edge PLY along the stab. T E , top'n'bottom . as its stiff . or alloy . or carbon , being in the 22nd century ? .
Got to see That dosnt dig into the surfaces of the elevator , etc .This assumes you throw the hinge wire in af ter everything else etc .
YOU can see , deflected - theres not a bump or a gap . Hopefully . Which seems to be the main point of it all . I cant see much ' bleed through ' of pressure ,
as if it were ' FLOW ' it'd be going aft , up'n' fwd. - around - and sucked out where iot'be blown in . or if its up & topside , it'd be near sealed at full deflection .
So it might get you tighter cleaner more controlled coners . and hopefully stop BOUNCE / Bobble on exits ? ? . being more efficent .less variable pressure fluctuation , and so forth .
