[QUOTE="johnful, post: 384645, member: 11662"] Hi Debbie, Given that the screw turns when adjusting, you might be missing the lock washer. You should be able to find one at Lowes or Home Depot for a few cents. It'll stop the screw from turning as you adjust the knob on the other side. The rubber washer under the knob keeps it from vibrating loose. You could find one of those at lowes or Home Depot as well. I had to get one for the lap nut on mine as it was missing. No matter how tight I made the lap nut, it would loosen up in a few minutes. The rubber washer solved that. J [/QUOTE]
