This is an unedited series of videos showcasing some experiments I have been doing trying to repair damaged pinball ramps for which there are no replacements available at the present time. In this case, I’m working on a Bally Party Zone ramp, using different types of epoxies, plastics and adhesives. See work works and what doesn’t. In the end, I figured a creative approach using laser cut plexiglass tabs which were attached to ramps using two different types of adhesives.

Making a pinball board test rig using a PC power supply

Here’s a quick video that shows how to take an old PC power supply you may have laying around and use it to power up pinball boards for testing. I use the Bally-35 MPU board as an example of how we can set this up to do board work on the MPU while it’s outside of the actual pinball machine. This is great for testing things while you’re refurbishing a board that’s been giving you problems.

The Great Switch Matrix Wild Goose Chase!

Here are six videos of an 8 part series of clips I shot this past week while working on restoring a Bally Theatre of Magic game.

What’s interesting about this series is you can really follow along with me as I fumble around trying to figure out what’s wrong. This is an all too common path many enthusiasts take which often leads them back to the beginning of the trail and emphasizes a number of common troubleshooting principals.

At this point, I have a working game except for two minor glitches with switches: An opto in the ball trough is not working, and it’s causing the game to kick balls into the shooter lane when powered up, and the EOS switches on the flippers are not being registered by the MPU. The solution to both of these issues was finally found and may or may not be what you expect. Watch the series to find out!

Tips and Tricks for touching up damaged/worn pinball playfield graphics

I recently picked up a very nice condition game but it had an odd damaged section in the middle. Obviously this needs to be fixed and in this series, my lovely assistant Brandi, helps me with playfield touch-ups and gives us some tips and tricks.

Here’s a picture of what the game looked like before:

Securing and adjusting stand-up targets and their leaf switches

On many games such as this Theater of Magic, there are stand-up targets in the middle of the playfield that take a constant beating from the ball. The switch blades in these targets, as well as the entire assembly will often get bent out of position and stop registering. I demonstrate how to use a simple tool to fix the leaf switch blades and put them back into position, as well as some other techniques for making sure the targets are solidly-attached to the playfield.

Stand-up targets have changed very little over the decades so this technique works on both old and new pinball machines.
