I found this web page:
I hear just shimming with electrical tape or glue had been done. I'll try putting the tape on, but first I'll have to see how easily the hand grip comes off. Maybe need to lube it? It already is some what loose but only I know spinning around. To take it off axlily I don't know how much friction there is in that plane.
I will check with the shop I bought it from later today and see if they have ideas too.
