Hi Guys, I cannot get the new balance staff riveted to the balance.  I've tried the smallest domed punch that will fit over the balance and then i tried several slightly larger punches.  I tried light taps and moderately hard taps, but the balance is still very loose on the staff.  The replacement is identical to the one I removed.  The attached picture of the staff and balance are after trying to rivet.   The other picture shows one of the domed punches; I've seen pictures of other punches
