Hey Wong,
I took Tom's description as moving the stop to the centre and you can use a bolt with the head on. In fact it would be better with the head on, as you can hold it still whilst tightening the jam nut. Essentially, you are copying a gib adjuster or the tappet adjuster on an engine - just a little bigger.
The other suggestion was to place two clamping bolts, rather than the single one you have now. These are not the small bolt you currently have locking your stop, but the one that holds the actual aluminium bar to the lathe. Having 2 bolts (close to each way) will give better clamping and less chance of it moving that a single central one.
Here is a real quick and dirty sketch that may help (not to scale or convention etc).
