Job 5: Replacing Inserts
Every one of the 21 inserts on this machine are concave and/or discolored thanks to the heat of the bulbs over time and it really affected the path of the ball. In fact, a light plunge to the top would sometimes get stuck on one of the top inserts.
. The first job was to remove the old plastic discs. First, I traced the edges with an X-acto knife and then, with the heat of a hairdryer to weaken the glue and a little pressure from behind, I popped each one out.
Here are some of the old inserts. You can see that three of the red ones are a lot more faded than the fourth.
The new inserts needed to be worked over with various grades of sandpaper and the edges needed to be roughed up to better accept the new glue.
A coat of plastic primer on the edge of each new insert and strong epoxy inside the holes and each one found its new place.
Beautiful! Here's a look at the whole playfield with all-new inserts:
