...until you put them on a playfield. I'm in the middle of a playfield
swap, and am getting started by putting a lot of new stuff on the new PF
first. So, I started with my nemesis: pop bumpers. Don't get me wrong,
they're not super hard, but I'll be damned if there isn't, still, a lot
of parts and what not in these things.

Really makes you appreciate when a game has working pops, knowing all
the parts involved to make it happen!

Ah, but on the other hand a game with many other good features and
layout, you won't really miss them as much as you might think. I have
an Elektra, and it's pretty darn fun without pops.

I have some pops that are pure evil on some of my other games...you
know, the ones where the casual slow ball gets blasted right between
your flippers at high speed. Simply...pure...EVIL! (but I love 'em)

Good question. Harry Williams designed the first game that used them,
Saratoga in 1948 (according to IPDB).
Harry is responsible for a lot of pinball inventions, so he very likely
invented the pop bumper. Wayne Neyens has the patent on the pop bumper
spoon switch though, and that was in 1948 also.

Given how the parts are basically unchanged from 65 years ago, the two
ideas together (skirt scoring and pop ring) have to be the out of the
box best-designed mech in pinball. Cleverest, most efficient, number
of moving parts. Compare that to flipper units and slingshot mechs -
different designs for different companies, linear vs. crank, big
changes over the years to increase power and durability.

If it wasn't for the hassle of the lamp socket lugs when removing the
pop's base (bending and unsoldering them, that crap) I would call pop
units the all-time perfect mech, but then I particularly hate messing
with those stinking lugs. : )

I know how you feel, just recently shopped my Safecracker. With the 2 drop target banks right next to the popbumpers (removed these first) and the wiring loom passing next to that, it's been quite a challenge..

I guess that's why Bally went to the pop bumper that mounts from underneath
the playfield. I'm not sure if they were as reliable as the Gottlieb ones,
but I haven't heard of many complaints.

The other huge invention was the flipper HOLD coil (i.e. dual-winding coil).
I don't know what game first introduced this, but those original games had
to have weak flippers just to prevent the coils from burning up. By the 70s
the EM games had flippers that were just as powerful as many of the later
games, but it's hard for me to define that exact point in time.

I took apart pop bumpers on a Xenon recently. Since I don't own
current game ie. ACDC 1. why are the pop bumpers so much more
responsive than a game like Xenon? Coil strength? 2. On current games
does Stern still use the light tab nailed to the pf? Why can't it be a
Molex connector? It would make things much easier. It's effective but
a not so fun job. Is it the cost?

Could be, Bally pops of that era have a different 'feel' to them.
However, they should still be responsive - do you have switch caps on
them? Also double check the adjustment, you want the spoon switch to
offer barely any resistance to the pop skirt, to make them more sensitive.

You rarely need to take pops apart. Doubt they use a connector and I
wouldn't want them to, too much vibration. (Actually I think they use
LEDs in the pops now)

Sorry Scott. I should have been more clear and had more detail. My
center pop bumper had the ring separate and fall off during a game. I
replaced the ring. So the pop bumper works as it should except every
once in a while a direct hit at 12 o'clock results in a dead bumper
effect. The reason I ask about Stern bumpers is when I played ACDC
those bumpers are very fast. I've played enough Bally games (Dr
Dave's) to know how they should feel. Are they a different design?
Remember all I know is Bally games so I have no reference point. Not
even Gottlieb em games. That is why I ask. It is just cumbersome to
take a Bally out and thought there might be a better mousetrap.

Yes I have caps on all bumpers. I'm getting better with spoon
sensitivity.
Scott I always appreciate your help.

Skippy what game are you working on?

Aeneas: that sounds tight and a lot of work. Are the target banks
wired? Wouldn't' Molex connectors make that easier?

Yeah, the early bally's have the type of pop body where you can't get
the ring out without pulling the whole thing apart.... now THAT's a
PITA, since the part that's replaceable easily (the ring) isn't on that
era bally.

The dead spot is going to be related to the spoon adjustment. You can
put a bit of graphite in the spoon although I've never had to do that.
Replace the switch, too, as it's probably been adjusted/maladjusted over
the years.

Also check to make sure the point of the pop bumper skirt is exactly
centered in the spoon. There should be enough play in the screws that
fasten the switch assembly down to move it slightly in all directions. When
centered, the first movement of the spoon switch when you touch any side of
the skirt will be in the direction of closing the switch.

As for the "kick" of the pop bumpers, there are many things that control
that. Ignoring EMs for now,
1. The coil. Lower resistance (less windings, thicker wire) will provide
more kick.
2. The voltage. For a given coil, higher voltage will provide more kick.
3. Any mechanical binding will interfere with the operation (SS and EM)
4. Software can pulse the coil longer to provide more kick. This should be
constant for a given game.
5. The shape of the spoon itself can effect how fast the switch responds to
movement of the skirt.

Ring rods come to mind, make sure they travel centered of their PF holes.

OK, I'll take the bait. First of all, Bally Bumper did not use "pop",
"jet", or "thumper" bumpers (pick your name dependent on manufacturer),
which is what the OP is referring to. Secondly, read the notes under
the Bally Bumper entry:

"Contrary to widespread belief, 'Bumper' was not the first pinball
machine to have bumpers. Bally copied the idea from Pacent Novelty's
1936 'Bolo', a game that came out several months earlier. Bally did
change the bumper design enough to obtain a patent on it."

So, as usual, Todd, you're wrong.

Methinks the word "pop" trumps the word "active" in Terry's statement.
Even if it didn't, the discussion has revolved around pop bumpers, not
active bumpers.

I agree that the argument is moot. I should know better than to take
the bait, and debate with such a mental giant. I apologize, and it will
never happen again.

Have a great day!

I may be wrong on some of this, all from my fading memory, but...

There were also those modular pops that Wico put in the few pins they
made. I remember from their catalog that they did modular kicker
holes too, maybe some other mechs. The pops weren't the same ones
that Bally used were they? Not sure how much of the Wico ones were
included in that unit, like the spoon switch.

Are you referencing the pops that are in games like Fireball Classic?
They are somewhat different than the pops from Xenon?

Yep, Wico made them, and classic Sterns used them around F2K. Then, DE
used a similar modular design later.

:-) Well then... since you asked.

I'm not sure when they started, but 70s Gottliebs used a relay to make sure
that any small switch closure on the pop bumper created a full stroke on the
pop bumper. Bally and Williams games didn't do this, the switch directly
energized the pop bumper. As far as I know, sling shots never used a relay,
so the kicker action would be proportional to how hard the ball hit the
sling.

What's funny is that my Williams OXO "seems" to have livelier pop bumper
action than my Gottlieb Spirit of 76. I don't know if this is inherent in
the design, or just clean/adjust differences.

Gott pop design is not inherently wrong, just clean it up and unwind
from 2.8 ohm down to 2.2/.3 and you will be loving life with snappy
too-fast-for-era action on an old EM. Make sure to put down some mylar
or your under pop PF will quickly go away particularly if you don't
clean, heat gun with Johnsons, and put down regular waxing.

Now on to pop bumper relays...

1/3rd from the top, dead center, to the right is the pop bumper relay.

Ah, but OXO has DC pop coils, IIRC. GTB didn't start using DC coils
until Cleo. There is really no comparison between AC and DC pops. DC
pops are so much more livelier.
