My KR-2 has 6061 aluminum flanges for the flap bellcranks. I found them in the local True Value Hardware store. I drilled a 3/16-inch hole through the flange and ¾-inch aluminum tube to bolt them in place.
Sid Wood KR-2 N6242 Mechanicsville, MD, USA That is pretty much what I have in mind, except I would like to find (or make) an aluminum flange to replace the clamp collars, then glue AND rivet that flange to both the torque tube and the bellcranks. The tube stops could be made the same way. Serge Vidal KR2 "Kilimanjaro Cloud" Paris, France
