You may know that my husband and I collect and restore pinball machines. Here’s an inside look at a small project. This machine is Duotron, Gottlieb, 1974. It got new legs to make it a little taller, and it’s been a few years since it’s been cleaned. Notice that the white rubbers need to be wiped down. A more noticeable issue during gameplay was after the plunge, when the ball shoots up to the top. Pay attention to the rubber disk in the upper left hand corner in the video. The bounce was more of a “thunk.”
It wasn’t easy to pry off that dried up hunk of rubber. Dwayne had to remove the upper apron to get a good grip. Here’s the bounce with the new piece.
Can you tell the difference?
