After inserting the fixed and sliding shafts into the leadscrew support they should rotate with no binding. Be careful - The pin coming out of the end of the fixed shaft (which is the natural thing to grab onto) can have sharp edges. Mine had some binding. I took some 600 grit sandpaper, wrapped it around the fixed shaft and twisted the fixed shaft back and forth a few times. Burrs (indicated by the arrow) immediately became obvious. I filed these down, and the binding disappeared. I didn't have any problems with the sliding shaft, but you should check yours.

The screws from the top and bottom fit in the big square groove. This allows the fixed shaft to rotate freely, but not to slide in and out of the leadscrew support. Smaller...
