TL;DR

Technical deep-dive on drop target mechanics and replacement procedures across EM pinball manufacturers.

Summary

Nick Baldridge explains the mechanics and design of drop targets across pinball manufacturers (Gottlieb, Bally, Williams), detailing how they function and their engineering differences. He then provides a detailed technical guide for replacing drop targets on Gottlieb machines, including step-by-step instructions for removal, cleaning, and inspection of related components.

Key Claims

Notable Quotes

“When you strike a drop target with the ball, it pushes a ledge that you can't see from the player's perspective off of part of the playfield and allows the target to fall.”
Nick Baldridge @ early — Clear explanation of fundamental drop target mechanism
“Gottlieb invented the drop target and so they came to perfect them in the 1970s.”
Nick Baldridge @ mid — Establishes Gottlieb as innovator and refinement authority on drop target design
“I don't want to say they're inferior because that'll ruffle feathers, but they're not quite as simple in their design.”
Nick Baldridge @ mid — Diplomatically positions Gottlieb as superior while acknowledging sensitivity in the community
“Bally drop targets are typically thicker, and the problem with their drop targets is that because they are thicker, there's more surface area to absorb the impact.”
Nick Baldridge @ mid — Technical explanation of why Bally targets bounce back more frequently than Gottlieb's
“This is much more of a problem on repro new drop targets than it was on the originals, and this may be down to the type of material that's used or some other factor that's invisible, because they appear identical.”
Nick Baldridge @ mid — Points to quality/material issues in reproduction targets vs originals
“Williams drop targets were much larger so if you look at a game like Grand Prix which was one of their last EMs the drop targets have a much larger surface area”
Nick Baldridge @ mid — Specific example of Williams' distinct design philosophy from Gottlieb
“Over many, many years of doing this, it'll start to wear a hole. It's metal-on-metal contact, and you may run into a situation where one target doesn't reset all the time, but it does other times.”
Nick Baldridge @ late — Describes common wear failure pattern observed in field maintenance

what's that sound it's for amusement only the em and bingo pinball podcast welcome back to for amusement only this is Nicholas Baldridge today i thought i'd talk about drop targets drop targets are a favorite target type of mine and the way that they work is pretty neat and also pretty simple. When you strike a drop target with the ball, it pushes a ledge that you can't see from the player's perspective off of part of the playfield and allows the target to fall. The falling action happens because of gravity and also because of a spring that's hooked up to the target. When the target falls, it pushes a switch. the switch allows the game to score and it also tells the game that this target sequence has been completed. So for each additional target in the same sequence group when they fall it scores and once the game sees that all the targets in that sequence have fallen it will trigger some special action of the sequence. Perhaps it will reset the target bank. Perhaps it will give you a double bonus. Or perhaps it will do something else entirely. This depends on the manufacturer, also the game, of course. Every game is different. Drop targets between manufacturers were also different. Gottlieb's drop targets are pretty simple. There a space in the target body that a little arm goes through There a place for a spring to hold onto And there a nice ledge and then a very nicely shaped target Now Gottlieb invented the drop target and so they came to perfect them in the 1970s. Other manufacturers also use drop targets, but their drop targets, well I don't want to say they're inferior because that'll ruffle feathers, but they're not quite as simple in their design. So, bally drop targets are typically thicker, and the problem with their drop targets is that because they are thicker, there's more surface area to absorb the impact. So, sometimes you will hit the ball into a bally drop target, and it'll just bounce right back. This is much more of a problem on repro new drop targets than it was on the originals, and this may be down to the type of material that's used or some other factor that's invisible, because they appear identical. However, when they're in the game, they do not play identically. Williams drop targets were much larger so if you look at a game like Grand Prix which was one of their last EMs the drop targets have a much larger surface area Gottlieb's original drop target design was not that dissimilar however they quickly improved and improved and eventually got to the point that they were at their peak in the 1970s. So for tech today, I wanted to talk about replacing drop targets. And this is a frequent topic of consternation And specifically we going to talk about Gottlieb drop targets Again I prefer the way that they engineered However similar techniques can be used for Bally or Williams drop targets. Just depends on which game that you're looking at. But for Gottlieb drop targets, they were fond of including many, many multiple drop targets in a single bank. If you look at a game like Target Alpha or El Dorado, those games have tons of drop targets. So the first thing you need to do is loosen the entire bracket that contains the drop targets from the playfield underneath. When you do so, it'll pull the targets through the playfield and you'll be able to access them from the top. However, you can't just remove the targets now that you have it loose from the playfield. The next step is to loosen and remove a bottom plate that's underneath all the targets. and that's held in by four or six, maybe eight screws. It depends on how long the bank is. Once you've removed that, you'll have access to the targets underneath. From there, you need to remove the spring that holds each target and helps it to drop. Then you'll be able to remove it from the arm that helps it to reset. And from there, you can pull the target out from the top. Once you've removed all the targets, you'll want to clean them, of course. If you're replacing them, you'll just want to clean the area where the new ones are going in So all the arms that stick through the targets You want to clean the arm that raises all the targets at once You want to change the coil sleeve on the coil that does the resetting And you want to inspect that coil and make sure it's good and doing its job. The last thing you want to check is the reset arm itself. is a little plate that is actuated by a solenoid, and it pushes all the arms at the same time and raises all the targets. Now, over many, many years of doing this, it'll start to wear a hole. It's metal-on-metal contact, and you may run into a situation where one target It doesn't reset all the time, but it does other times. And this is either due to gunk. I've had games where the operator has put grease on the arm, and of course that becomes gummy over time and then sticks. You want to clean that off and then check. But if it's worn a hole through, then you're going to need to replace the fingers if possible. and I would check with Steve Young at Pinball Resource if that were the case. And it doesn't matter the make. You know, it could be Bally Williams or Gottlieb. You just want to probably check with him first and see what he's got. All right, well, that's all for tonight.
