Taking slop out of ballcups
If you want to remove slop without binding, go to your local hardware store and pick up some teflon tape..the kind they use to seal threads in plumbing pipes. Its very inexpensive. Put a very small piece of this over the ballstud and snap the cup back over. Remove any excess that might be hanging out with an exacto. Your slop should be gone and still move silky smooth. If the slop is still there, keep adding layers and snap the cup back on until the slop is gone. Give it a try and let me know what you think
