An area of the playfield I’ve been looking forward to working on is the mini playfield and the pop bumpers that live beneath it. I’ll also take the opportunity here to look at the bank of 5 stationary targets that sit just to the left of the pop bumpers. It’s going to be a long update I think and lots of photos to look through. So hopefully you hang in until the end 🙂 The starting point is good. All plastics and posts are there. The mini playfield itself is in one piece, although I can see some small cracks at a few point that will need to be looked at.

One of the final parts of the play field to get some attention is the pop bumpers. The main reason I had left these for so long was due to waiting on parts arriving from the US. There were some immediate issues I noticed with the pop bumpers. Firstly, the lower of the three should have a Medusa cap and not the “1000 when lit” instructions. The “1000 when lit” and “3000 when flashing” apply to the top two bumpers. These are activated by achieving one of the two skill shots on the upper area.

I’m beginning to run out of things to do on the Nugent now. I’ve gotten into most corners of the machine and sorted out many issues as I’ve gone along. There are two main things left to look at – the drop targets and 3 pop bumpers. I’m going to focus on the pop bumpers and get them serviced.

Awhile ago I replaced the 3 caps on the pop bumpers (seen in an earlier post). Now it’s time to actually remove all three pop bumper assemblies to clean and service them. At this point the only real complaint I could make about the pop bumpers is sometimes they don’t activate when they should. Most likely solved by cleaning and/or adjusting the switch.

There is a bit of work to actually get them out as I found, but once I had managed to do one, the others were much easier. I decided to do one at a time. That way I had two working pop bumpers to use as reference in case I mucked up.

To begin with, I need to remove the cap and also undo two screws that sit inside pop bumper. The two screws attached the pop bumper body to the playfield. But I can’t simply lift it up as the bulb socket is soldered under the playfield and the metal ring is attached to the plunger.

I performed some minor changes to the playfield today. The original Nugent machines came with solid red lane guides at the top of the playfield. They look OK, but are a little dull. When looking around at various pinball spare parts shops I spied a few transparent red guides that would look awesome, so I purchased them. Replacing them is as simple as removing two screws.

This is how the original red guards look:
