This is an appeal for information from glider wing builders.
Steve Leisch (Kit A208) has realised that there are 2 Tufnol bearings part
number GAB03 that are not referenced in any of the build documents.
I have checked with Karen at Europa and can confirm that GAB03s are diamond
shaped Tufnol blocks with a hole in the middle (which is large enough for
the airbrake push rod to pass through). Talking to Nev, I believe they are
fixed on the root rib to act as an inboard bearing for the airbrake
pushrod. The end of the pushrod enters the cabin and is attaches to the
cables as per Fig 11 on Page 28a
In the Glider manual, section 8-13 refers to cutting the air brake push rods
(roughly) to length and fitting the bell crank end. There is no detail for
cutting the holes through the ribs forward of the spar, finalising the
length, attaching the inboard end fitting on the pushrod or the final
connection to the cables.
As no one at Europa has any further information I will try and collect as
much as I can. I would be pleased to have
have any notes, pictures or drawings you may have.
When I have got this together I am happy to produce a Build manual
supplement covering this area.
