long storry short, I figured out my speedbag problem. the swivel is the old chainlink type and because of that my bag hits on the seems which makes for untrue rebounds. I need to rotate it 90degrees so it hits on a flat panel.

So, I need to add another piece to the sivel or to the bag. I need something about half an inch wide to connect the chainlink and the leather loop on the bag. Thus, I'm adding a loop (either round or tear-dropped shape).

Any ideas what I could use? I was thinking hex bolt but I wouldn't be able attach it to the leather loop on the bag since it doesn't open...

any engineers out there?!
danke guys.
