I had to thin the nut that holds the pulley on -- just stuck it in the three-jaw and faced it down. The pulley and the end cap are two different pieces, in case I need to change out the pulley for a different size later. The knurled nut on the height-adjustment stud was my first experiment in knurling. What a pain. Maybe I'll enjoy that more when I'm better at it.
