The projections on the 303282 friction block must slide into the slots in the end of the handle in order for the screw hole in the handle to line up with the threaded hole in the shaft. Many say the friction block is missing when it is actually stuck in the handle. Rapping the open end of the handle against the work bench is often suggested, but this can break a handle made brittle with age. I like to fish them out with a bent coat hanger.
