Flipper rebuild steps 10-12: end play and alignment

Steps

• Leave a little up and down play in the bat so it doesn't bind; the factory spacer tool between bushing and pawl is .030 inch thick (about three business cards).
• For a rough position, put a toothpick in the alignment roll pin hole behind each flipper and set the bat against it. Don't push the roll pins through the playfield.
• For the final position, lay a straight edge along the inlane guide; the ball should run off the guide onto the bat in a straight line.
• Raise both flippers and check they look symmetrical. A filed coil stop or a worn rubber plunger stop can stop them matching.
