9 months later and finally the end product!  Putting some protective padding on the sides of the playfield was a great idea as the hood was up an down like a yo-yo there for a while. Played a few games and after a few adjustments it plays perfect. I'm super happy with result. I can say for certain I wouldn't of got this sort of result without the huge amount of info on this forum. Thanks.... I'm off to play now!!!!
