Tim Arnold believes that playfield prop sticks are bad--flexing the
playfield causes paint cracking. Instead, on most machines you can just
lift up the playfield and pull forward until the set position is reached,
then lift up all the way until the playfield is past vertical, resting
against the backbox. Be careful with the playfield in this position. If
bumped, it could fall hard and damage itself and you!
