Sorry, just another thought. Your weight might be way too heavy. As it is detached from the cross bar, grab the opportunity and try it with lesser weight. You might even try the first run without any additional weight, just with the cross bar itself. Then gradually increase the weight by adding smaller pieces. I just measured the weights down in my cave. One lead ball weights 97 grams. The whole keeper arrangement, incl. swivel and cross bar is about 10 gr. So I can vary the total mass between 107 gr and 398 gr, with 1 .... 4 balls. The usual mass is 1 or 2 balls, seldomly 3, very rarely 4.
I just had a close look at my swivel. It looks it has a fully closed ball bearing. Again, this is very important.
