A few months ago I removed the plastic window from my CFTBL playfield and after putting it
back I had the hardest time adjusting it. It still seems to really affect how the ball rolls.
I know there are nuts underneath the playfield that I can adjust to move the window up and down
but I can never get them just right. Also the gap between the plastic and the playfield seems bigger
'upfield' than towards the flippers.
Does anyone know a good trick to get this right?
