Been away from the model for a few days, this afternoon made and installed the pivot bearings/rod to connect the booms together. Nice to see some parts attached and moving! A couple small fasteners, then I can work out the motor mount inside the lower boom to power the cylinder. Actually, that brings up a question - what are the proper terms for the two booms? Lower/Upper, Inner/Outer, Fred/Ethel?? Must be a name for them...
