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.
I guess I've watched too much orf the "A Plane is Born" TV show recently. The Europa uses a lot of aluminum-to-aluminum glueing and riveting. And that would make for a very easy installation on board the aircraft. Since the plane is already built, the difficulty is more in the fitting than the designing!

Although I welded my bellcranks to these collars, you could also screw them together if you made your bellcrank cover one half of the clamp collar and used about four screws. You can see these clamp collar things at http://home.hiwaay.net/~langford/kcontrol.html , along with the general idea of the flap torque tube. The very last picture shows the flap torque tube and flap actuator motor, but it eventually ended up under the pilot's seat. I have a more recent picture of the flap motor and bellcrank stuff somewhere that I'll try to dig up tonight. The other end of the torque tubes just extends out through the stub wing rib (which acts as a bearing), where another bellcrank and clamp collar setup translates the torque tube rotation into pushrod actuation for the flap bellcrank.
