I have this small issue with the new W66 backing plate that I got together with the So1o Kit. I don't know if anybody can see it from the picture below but the thread hole is a little bit off-centre. So even without a pad it would 'jiggle' a little when spinning and it's a bit annoying sometimes. And it's very difficult to get even the WDF pad to really centre.
Need some help and advice.
