What can I use so a bird feeding station will not move at all? One of the screws on the 2nd lowest part of the pole so another new hole had to be made on the other side with bigger screws. That part is tight but it moves back if pushed lightly but is secure and will not break or fall since of those 2 screws. Still I need something so it won't move at all. If you use some force and twist you can turn that area around causing the top to turn but less now than before since 2 screws are there. Please help. Thanks.
