G'day all, very quick update:

haven't gotten too much done to this game lately due to other commitments, but i have started refitting all of the removed items from underneath the pf, targets, kickers etc. I got to refitting these rollover buttons, only to find.. and i have come across this a few times with using mylar on the PFs, that when installed the button sits slightly below the pf surface when pushed in, due to the thickness of the mylar i use... which would result in stuck balls!! not good

here is my solution.. pretty self explanatory in these pics, after removing the clip (carefully  ) i remove the large washer from the underside of the rollover and place it on the top side over the button shaft! Resulting in the rollover sitting nice and level with the pf surface when the ball rolls over it.. and less chance of stuck balls
