Quoted from cottonm4:

OK, boys and girls, I traded emails with Kerry at Mantis; inquiring about the Stern slingshots, coin door flaps, coin door skins, and the 3 beauty angles that surround the coin door.
He said he made coin door skins at one time and they did not sell.
Basically, we are dealing with the law of small numbers with these parts. Unless he gets back to me with some surprise action, I don't see any of these items happening.

Odd as you think that the skins would sell better than the guide sets for "x"

Skins you can use on any title, the guide set only on one. I'll assume the guide sets are made as needed and some of the skins might need a third party involved and thus a minimum order number.

#6702 87 days ago

Would really love a couple sets of slingshots. Is there anyone else that does this kind of thing that we could approach?

Maybe pinballlife can be convinced to remake these like he did with the flipper mechs.

#6704 87 days ago

I'm projecting here, but I worry Kerry is hung up on old experiences when these scratch builds and restorations were not as in demand as they were even 2-3 years ago. He told just a couple weeks ago it's unlikely he'll do another batch of Star Gazer ball guides. Or maybe he's just burnt out? I hope not!

How many scratch builders need a coin door?

With prices of everything shooting to the moon, how much would you pay for a pair of sling levers?

The last time I canvassed people about price, I think &25.00 each was about what anyone would pay.

Maybe Pinball Life would be who to call as PL said he would not step on Kerry’s toes.

Yeah, I'd say $25 is my limit. I could commit to two, possibly three additional if my next project comes through soon.

Bally coin doors skins seem to be good sellers.

#6709 86 days ago
Quoted from gdonovan:

And Marcos used to stock classic Stern coin door skins.

#6710 86 days ago
Quoted from bluespin:

We’re they just working off of NOS stuff until sold out?

#6711 86 days ago

I imagine the Stern coin door skins Marco used to stock were the ones Mantis made?
One thing worth noting, I have discovered their are actually 4 different versions of the Stern coin door skins.

First version - All prior to Magic. Coin reject button around the centre position.
Second version- Magic, Trident, maybe others, Coin reject on the left side.
Third version- Meteor (some but not all) coin reject hole & mech mounting holes all about 10 mm to the left compared to the previous version. Double switch bracket.
Forth version- Later Meteor & all from then on. 3 holes for mounting replacing the 2 on all previous doors, no cutout on the top right edge of the inner skin (unknown purpose) no extra hole above credit button hole in inner skin (unknown purpose)

The only two versions that can be easily altered to be interchangeable skins are the MPU 200 versions 3 & 4 as it's essentially only the 2 or 3 mounting holes the difference. The MPU 200 mechs won’t line up on the earlier doors as they are actually slightly different design mechs as well as positioning so won't line up with the coin reject button & coin chutes.

The demand would mainly be for the last MPU 200 version I would assume.

#6712 86 days ago
Quoted from cottonm4:

They weren’t nos, and neither are the Bally skins they sell. They either bought from another vendor and marked them up, or sourced from a manufacturer. They probably did the later.

The demand would mainly be for the last MPU 200 version I would assume.

Most if not all of the people that converted mpu100 pins will want to buy the fourth version skin to make their coin door look factory correct.

#6714 86 days ago
Quoted from bluespin:

Most if not all of the people that converted mpu100 pins will want to buy the fourth version skin to make their coin door look factory correct.

Yes, that's true, but they will also still need to find a complete MPU 200 donor door to get the mechs to fit the latest version correct style skin if they were available, as the "guts" of their MPU 100 is not suitable to change over, unless you drill & tap new hole positions to mount the earlier hardware.

#6715 86 days ago

anyone know where I can purchase a link/plunger for the drop target mech? ours melted along with the coil and I'm not having any luck finding one. maybe a bally version will work? part number is #A-398-STN

#6716 86 days ago

I believe most metal stuff with Marco Specialties is sourced out locally in their area. Not interested in making stuff if others are going to do the same. I was interested in trying to do classic Stern target banks, but waiting to see if multiple parties do anything. Risky business with everyone doing the same thing.

PBR sells link material (fiber board) in their tools / supplies section. There are pretty easy to make with common hand tools and a Dremel.

Quoted from slochar:

I really hope someone like Pinballlife will make these. Mine have so much wear they nearly hit the nail! I think if some people checked their slingshots for wear & realised how worn they were & how much better it must play with tight ones they would have to sell quite a few sets. I would pay $25.00 or more.

The point I’m trying to make is that I don’t think $25.00 is enough of incentive for anyone to take these on.

Quoted from cottonm4:

Tough sale for sure. You have the base fabrication (laser or water jet) and then have to bend and rivet/press the pieces together. I'd wager minimum a $100 a pair with no coils or plunger and thats a WAG.

New DE/Stern style units are $50 fully loaded each from Pinball life but only fit a narrow range of classic titles. Dumb luck the DE units I had fit Seawitch so I went ahead and ordered new ones for Quicksilver... and the switch holes are not in the same locations =(

All classic Bally the DE ones won't fit either, every one I have checked so far Bally had lamps right behind the switches and it doesn't work.

I have a feeling I'm going to be sitting on the new DE units for a long time unless I cannibalize them for parts.

#6722 86 days ago

yea the plunger part is good the plastic link is melted so I need that. figured easier to find the whole thing.

Have you tried replacing the plunger and adding a brass washer to the connection?

Quoted from Joydivision:

They do play great. I got some NOS ones several years ago from ebay and they ended up in my Meteor and Flight 2000 games. Huge difference.... so much so I checked my other bally/wms games and ended up replacing several there as well. If it rocks laterally at all, it gets replaced.

I always put new switches in as well. The old mangled ones don't adjust very well since the blades aren't flat.

https://www.pinballlife.com/slingshotballshooter-plunger-and-link-2-18-plunger.html

No, I haven't replaced the plunger or added a washer, will look at that. The excessive lateral movement appears to be due to all the wear to the pivot pin & the arm socket.

That's good to hear that it does make a huge difference.

#6726 86 days ago

You could even just try adding washers to your current plungers. I’ve found a lot of lateral movement eliminated by what I posted above though. The new plunger links are marginally thicker than original fiber ones, which also often have worn out link holes from years of rotations.

Another issue us the pivot point which is riveted in some cases breaks loose and causes slop.

A quick spot or two with a welder fixes that problem.

Here is the plunger and link. I think this I the assembly for the drop target coil. But not 100% sure. It could be for Stern flippers.

[quoted image][quoted image]

you can eliminate some of the slop by replacing the bracket with one from PL. You have to make a mod by notching out the inside hole under the base of the pivot pin. And you will have to drill one new hole for screw placement.

Another inisider came up with a way to replace the worn pin with a bolt that worked out for him. but I can't find the thread.

I think that is the flipper one.

#6731 85 days ago

Recently picked up a Quicksilver. It’s missing the metal trim with tabs that go on top of the backglass. Is this piece available anywhere or unobtainium? Would like to be able to lock the backbox. Thanks

Are you saying I cannot rob a sling assembly from my Robocop and move it to my classic Sterns? Was looking at the self-contained sling units. What are my options?

It depends if it has even holes or not.

#6738 85 days ago

I will pull my slingshots out & have a good look at what to replace & see how they can be improved with all the above suggestions.

I came across an old thread on the Aussiearcade forum last night regarding slingshot repairs done by a local guy I know. The repair is mentioned near the bottom of the page in the thread in link below.

I asked him about the repairs & he said he was able to machine new pins at his work to fit the sleeves, then the pins were peened on. Appears to be a great result. Assuming that if a sleeve has been bored out fairly evenly from all the movement, a slightly larger diameter pin should create a nice firm coupling again. Probably not viable to get done at a machine shop for most people but good to see excellent quality repairs carried out on original slingshots.

yea that's a flipper link/shaft. I'm pretty sure the drop target link is larger than the flipper one tho. looking like I'll have to remove one from a working drop and attempt to make/3d print it

#6741 85 days ago
Quoted from Joydivision:

That's the problem. A custom oversize pin can be turned, the pivot sleeve can be bored oversized for clean up, but machine shop time is not cheap.

Maybe someone with good rapport with Terry at Pinball Life can get some sort of ball rolling ( no pun intended).

Maybe Swinks can make the arm. If the ring and rod assemblies they make can take the stress maybe the slingshot arms could also. Just a guess.

I don't think 3D printed plastic would hold up the the rigors. But it is something think about. Maybe you could ask Swinks. He can 3D print in metal but I don't know the impact resistance.

#6745 84 days ago

I dropped the new Meteor 2021 code into my Meteor pin and I have to say I’m pleasantly surprised. The new code and stereo sound make it seem like a completely different game. The shots are all still there but my go to Meteor strategy won’t get me very far in the new code. The game is really task oriented now (like a more modern pin). I took the lazy route and just bought the plug and play kit off the Pinside market. Well worth the $169 in my opinion.

#6746 84 days ago

Anyone have a set of Star Gazer ball guides they are willing to part with? Mantis is out. Please hit me up with a PM.

#6747 82 days ago

Can someone with a Stars or MPU-100 game send a few closeups of the MPU connectors? Having a lot of trouble tracing down some gremlins on mine. One coil not firing at all. Some coils misfiring intermittently. Checked schematics but none seem to have wiring colors for the MPU connectors specifically.

[edit]

Oh sorry, just saw you specifically meant MPU.
------
Just be aware, there may be some errors in the original schematics.. I know mine had a wire mismatched. I think it was related to the bumper coil from the driver board.

#6749 82 days ago

How is the one and only stand-up target on Meteor wired up. I think mine had a diode and cap at one time but those were removed. Meteor 2021 uses that target a lot and I need it more responsive. This is what I did. Is it correct?
