Are the ball trough pieces from a Stern? Obviously a Bally coil but looks more like Stern parts. If those playfield hangers are from a Stern, they won't fit with a Bally receiver.

Scratch building my Star Gazer, I ran into a clearance issue with the older style Stern drop target mechs (not to mention also learning I had to file out the pass-through holes because the repro targets are too dang wide). I put a lie-down style socket in but Seawitch looks like it has more bulbs to deal with under there.

Quoted from gdonovan:

I'm using the Bally mechs on the four target banks, like I mentioned above odd that Bally had two plates, with and without cutout.
Usually the accountants will be all over duplication like that!

Right, I followed that but you cut the second one for clearance so I showed my solution for the same issue using the older style Stern mech. I also had issues with the repro flat top drops being too wide (since these mechs originally used the smaller chicklet drops) so I had to file out the holes. I love to see that Bally drops can be modified to fit Stern designs honestly

I also saw you mention you were going to route out your pop bumper holes to fit newer style mechs. I’ve had that thought for my older games because I hate the original metal base plate design. I don’t have photos at the ready but to fit one in my Trident, I just shaved down the plastic ring on the base plate. It did not solve the issue of new rings being too wide to pass through when installing a fully assembled mech however.

I'd rather modify a $15 bracket than a playfield, personally.

#186 2 years ago
Quoted from cottonm4:

You are probably not taking off more that .002 to .003 of an inch. once you are finished apply a little clear to the sanded hole.

It's closer to .15 inch (4mm) difference. Maybe more? I don't recall, but regardless, I'd rather mess with something reversible. I'm certainly not knocking @gdonovan's idea or work on this project. It's great he's doing this and sharing the progress.

Anyways, back to his show...

Quoted from cottonm4:

My math was off. Yours is off, too.
Back to the show.

Good lord

I’d recommend routing out a bit of depth with a forstner bit for the post screws to be able to bite more. Unless you’re using machine screws up from the bottom to mimic the carriage bolt method SEI did originally.

#544 2 years ago

When I did this on my Quicksilver build, it was a mistake to not sink them more. Only catching a few threads resulted in loose posts biting up the shitty Mirco clear. Had to replace them with machine screws from underneath.

#550 2 years ago

#6 - 2-1/4” machine screws work well without having to trim them. Hard to find specific length though and it looks like my order link from Bolt Dropper is dead. 2-1/2 and some super champs to trim will work.

Back off topic…

Quoted from cottonm4:

You are right. Stern Pinball was the first pinball after CC.

#rawhide/#Stampede and Disco were all before Pinball, however Pinball was the first solid state (though also released as an EM).

Huh, I get random pop fires on my Quicksilver and Star Gazer scratch builds. I wonder if adding caps would help. I just assumed I didn’t know how to adjust a leaf switch.

Quoted from gdonovan:

Oh, and I have one of this on order along with stainless. Going to make my own lane guides from here out.
[quoted image]

Looking forward to what you think of this. I’ve been trying to figure out what I need to make my own ball guides too.

I’ve debated buying a tiny 3D printer mostly because of those dang spacer posts being so expensive from the usual sources.

#868 2 years ago

Wow! PM incoming

#870 2 years ago

I’m in no rush for a generous offer! Thanks again!

#878 2 years ago

Curious, would you mind sharing a step-by-step on how you modify your lamp boards with those bussed resistors? (Possibly even with parts to buy from GPE or something?).

I've seen you post images a few times but haven't been able to find any how-to posts.

Thanks very much! I look forward to giving this a shot on the Stingray I’m patching up.

Finally modified one of my many spare LDB boards and it seems to do the trick. I may have a component that needs replacing. The L lane at the top flickers in attract mode and is off in gameplay.

Thanks again for posting the how-to!

I assume you nabbed those eBay ones out of Plano?

Awesome! I bet that's way more reasonably priced than having a complete glass shipped. Care to say how much? It was over $500 when I inquired a complete glass

#1270 2 years ago

I’m mostly interested in the mirrored versions he’s able to recreate (or in some instances, custom make). So do you feel a bgresto looks better than the film? It seemed like a very quick install. I assume you’ll tape the edges like bgresto does?

They forgot to put the switch stack in. At least the screws didn't poke all the way through!

Love this idea. I have couple old bally inserts boards that I'm now glad I haven't tossed out. Glad you're feeling well enough already to do more projects!

This may be a dumb question but the lamp driver board mod, the same principal and method can be used on an Aux board, right? I picked up a light (no pun intended ) Fathom project last week.

#1423 1 year ago

Sweet, an even better answer than I was hoping for! Maybe it wasn’t such a dumb question after all!

I have a PIN2DMD I got for my X-Files but didn’t quite realize how different the install process was to a ColorDMD (for which X-Files is somehow still not a title). I got overwhelmed by other projects and haven’t dug into it. Thanks for the reminder. Any tips/links on the best install process?
