If you over-tighten the bolts on modern pinball legs, you can strip both the bolts and the assembly you screw into, making it a real pain to firmly attach legs. I go over the process of replacing the inner plate to fix stripped pinball leg assemblies.
This is a short video demonstrating how to add a DBA (dollar bill acceptor) to a new Stern game (in this case, Jurassic Park). The older Stern games came with the cable necessary but now they’re not bundling them. I take a cable from Iron Maiden, along with a DBA I pulled from Wizard of Oz, and install it in Jurassic Park before I put the game on location.
Here are two videos of me completely rebuilding the flippers and flipper assembly on a Gottlieb System 3 pinball machine (Waterworld) – many of this information will basically pertain to most flipper systems on other machines like Bally and WMS, Stern, etc. I go through the whole process of replacing all the major wear parts on the flipper assembly even including the base plate and end-of-stroke switches.
Here’s part 2 (sorry I rarely edit these videos so sometimes my camera breaks it into separate files)
If the above is too slow, check out this time-lapse of rebuilding the flipper:
As work continues restoring this Gottlieb system 3 pinball machine, “Waterworld”, I rebuild the broken VUK (vertical up-kicker). This is from a series of videos where I rebuild a number of the core components on this game that’s been on location for probably more than a decade.
Here’s a short video showing the removal and maintenance on a drop target bank from a Gottlieb System 3 pinball machine – Waterworld.
