If it does start to give you problems there is an easy fix too
Use a wire coat hanger, cut the bottom section of wire out about 10-12 inches bend it into a "L" shape and put loops at both ends, the leg of the L loop will fit over your vertical spindle and your cone will sit down on time of it, and your thread can run up and through the loop at the top and then down to your sewing machine letting pull from the 'top'
