Ghostbusters Target Wedges

Finally got the parts back and did some final testing for a solution to the air balls off the X2 & X3 targets on the Ghostbusters pinball.

Basically the Stern targets are dead vertical and when hit bend back beyond the vertical which then allows the ball to go into the air. Bally / WMS targets leaned forward, so I devised a simple wedge that can be inserted into the existing Stern target assembly. This wedge now leans the target 4 degress forward from vertical and has been effective in stopping the massive airballs. I still get the random minor ball hop but has improved the design of the target and decreased the problem alot.

You will need 1 wedge per target. You will also have to source 1 x 1/8" longer bolt for the target assembly as there just isn't enough thread once the wedge is installed.

That should totally work. I used dead foam stop at the upper portion of the target on my GB prem, and that have fixed a lot of airballs. However the foam does wear away making it useless over time . These simple but effective target wedges should work great. Good design !! The ModFather

Brilliant mod Jady, every GB owner should pick a set of these up! Get rid of all those plastic airball protectors and get that factory look back again.

Swinks is a great guy I would buy with total confidence!

Ya. My "protector" even with washers rubs the ball as it goes up/down the ramp. These will be awesome....Also need to get the glue stuff to put together my swinks shooter rod mods!

did the kingsday17 code already expire? I get invalid

What other Stern titles (and specific target locations) could benefit most from these wedges?

#14 1 year ago
Quoted from northvibe:

the code is still valid for another 8-10hrs, ensure you use uppercase - KINGSDAY2017

also the parts can only be polished flexible plastic in orange, red, white, or blue and can be any parts not just the targets.

Quoted from RoyF:

not sure but will fit into the same target design, just it is well known that these 2 targets in particular on Ghostbusters creates the massive air balls.

#15 1 year ago

a person asked me how to change the colour... hope this helps

simple go to the colour currently listed at purple and click on it and a drop down of available materials and colours will appear, simply select the colour you want - remembering that the dutch colours today only get you a discount (Orange, Red, White and Blue). I did cancel white as a option a few days ago as it goes through a different polishing process and was breaking at the branches - sorry.

Just ordered, thanks Swinks, shame you don't include the longer screws, but I guess I should be able to source some easy enough from local hardware store.

Thanks for the support, tough one as shapeways is purely a manufacturing service and can't stock parts and I am in Aus.

Will these work on williams games too? I have a few that love to launch the ball

it the switch is a bolt together assembly - possibly though haven't checked the hole spacing and the ones that pinball life sell that match the bally / WMS are riveted so can't be disassembled

I think it was the color, switched to red and I saw it.

What type of screw is this? #6 32?

Please also give the exact length. Thanks.

Yep. That would be helpful as well.

#24 1 year ago

My apologies guys I thought I wrote it.

The current bolts are 5/8" so 1/8" longer = 3/4" is ample long enough

As for the gauge, I am a metric guy but in the manual on page 44 is a similar target assembly but with a 3 bank of targets and it states the bolt being a 6/32 x 5/8" so assuming the new bolt would be a 6/32 x 3/4". For me I looked through left overs and found the same gauge and cut it down so did not do a purchase to 100% identify the gauge, sorry - dropped the ball there.

#25 1 year ago

A 3/4" long #6 - 32 screw works perfectly.

#26 1 year ago

Great I am going to try this!

Just got pan head machine 6 32 3/4" worked great. Took off the plastic Air protector. Doing other mods and then I'll be trying it!

#28 1 year ago

Well still have some air balls launching across the game. My plastic Air guard was just rubbing balls as they went up/down the ramp. I'm gonna trim that and put it back in. But these wedges help for sure.

#29 1 year ago

You can try putting on a small piece of 3M double sided tape that is about 1/16" thick with just one side of the tape removed so it sticks to the other foam pad coupled with the wedge is very effective as well.

#30 1 year ago

I edited a picture that hopefully helps those that need it. I do admit that during the time waiting for refined wedges I installed 1/16" thick white double sided tape (near my thumb) behind the target to firm up the target and reduce the bend back and possible launch of the ball. Then when the wedges came I installed and didn't think to share that minor detail - sorry.

basically 2 install locations

Location 1 - brings the backing plate closer to the switch making it a little more sensitive. Adding the small piece of double sided tape will firm the switch up and reduce the effect of the ball getting airborne. I am playing with this set up and still get the odd minor air ball but not shooting over plastics and lanes etc and the switch is not as sensitive as original so not a given shot.

Location 2 - keeps the switch standard sensitivity but will still allow the target to tilt forward and when hit to bend back to a 90 degree position and possibly allow the ball to get airborne. Adding the tape will firm up and keep the ball / target at less than 90 degrees when hit and should be a improvement on airborne balls.

Swinks, I have installed these, IMO it does very little to stop airballs my 2x target, the ball hits my crossover ramp on my premium just like before the shim and current airball protector and pounds my playfield. Thanks but in the end I have yet to see any benefit yes I installed the correctly.

(I know this isn't your problem) Additionally b/c of playfield differences sometimes they won't work, example I can't install this shim b/c Stern original placement of the screw hole underneath on my 3x target, adding the shim just barely forces the switch to a closed state, if I try to drill another hole it will blend 2 holes into 1 and not hold to the playfield, very little I can do even bending the contacts as well I had to abandon these shims. I bet the shims could work on the target "L" to playfield wood as well, same concept if room allowed.

not trying to start a fight, nor am I asking for my money back.

I think a better air-ball protector is needed above the targets, Stern really failed us it does alot of damage.

#32 1 year ago

in the end it is a stern target design issue and whether it be my wedge or an air-ball protector these are trying to control a inferior designed target that produces airballs off high powered direct hit shots due to the angle of the target. In addition each game is slightly different and it was never claimed these wedges would totally stop airballs but reduce them - for me I was getting airballs on to the ramp (rhs) and even the shooter lane and now I have reduced them to occasion hops (air balls) of 1-2 inches.

try putting in the different foam or 1/16" thick double sided tape to space out the backing plate and switch - this will solve the sensitive switch state - as stated in the above picture.

alternatively buy a williams target and try in the game - I have not tried this.

otherwise I am sorry this was not a solution for you.

I have many problems of balls in the air in iron man vault, the targets are impelled towards the front but it is still crazy .

#34 6 months ago

it has been a while since owning a ironman so can't remember the target design but I did improve on the targets and now recommend a revised metal bracket.

swinks alright dude is it you that makes the stand target braces mate for games like Ironman and Tron where the stand up targets have a habit or leaning to one side?

#36 6 months ago

No I think that was mezelmod made “splints” I think to stop lean over
