This stuff not so much. The rust must have attacked the plating in some places. Once the evaporust worked its magic, the result appears to be bare metal.

The countersink screws that hold the wooden playfield back panel in place were really rusty and they now have a tarnished look with the rust removed. All in all a very pleasing result considering the condition. Will only have to buy a few pieces, rather than the majority.

Quoted from dudah:

Good stuff! Your hardware isn't that bad I imagine it'll give you some great results. Check my restoration threads, I use evaporust wherever I find rust and it does great! People seem to use tumblers but I've never gotten good results out of it. Just a mess cleaning up the screw heads!

Only used a tumbler once, the screws and post came out blackened. I wasn't impressed with the results at all.

Quoted from provato:

Thanks for the upload of the registration card! Your scan is great. I sent you my e-mail address in pm.
Evaporust and other liquids are good for rust removal, but glassbeating your parts in a sandblasting booth and then polishing them with a spiral sewn wheel + compound is the best option.
Experience with metal has tought me that the right mechanical way is always better than the best chemical way to restore metal parts.

Does the glass bead blasting do any damage to the nickle plated posts and screws?

Depends on how deep the rust has “eaten” metal.
You can also wire brush on a twin wheel or a dremmel for small parts.
And of course, after polishing (even metal without plating), you can zinc plate the part again for a professional restoration.

#105 8 months ago

Just curious and you might not want to share, but what did you pay for this game in this condition?

Thanks

Makes sense. If these were major assemblies that weren't easily and affordably replaceable then I'd look into replating options. I think the worst will just go in the bin.

$1200. Although once it's rebuilt, it won't be the most affordable game. I'm am however determined to bring it back, but if it was just about the money, don't buy games in this condition, especially if you can't inspect them in person.

Quoted from Pinballer73:

No problems, I'll scan it at 600 dpi and send it to you.
I tend to agree with your comments on cleaning metal. Overall I had terrific results with more than 3/4 of the hardware cleaned today coming out really nice..[quoted image][quoted image]

did it take longer to arrange them for this photo then to clean them? looking great!!

what media / polish did you use? Iv always had great results and the parts always come out super shiny

#110 8 months ago

It's been that long I can't honestly remember. I think it was corn cob and novus 2.

It doesn't look like much, but replacing that pile of posts is $$$$$. Crazy how much those cost.

That's for sure!

Quoted from provato:

I have another question regarding those large washers at the slingshots. Were these under, or over the slingshot plastics? Or maybe the plastic was "sandwiched" from both over and under with washers? And what part # (or diameter) are all the washers of the slingshots.

Here are some pictures showing the dimensions of the large slingshot washers.

Wow thank you for posting this! You really inspire me to begin my BSD project restoration.
Your caliper really puzzles me though on this washer... If I read the vernier scale correctly, the outside diameter of this washer is 20,2 mm = 0,795 inches.
There is no such diameter washer described in the parts list on ipdb! The biggest diameter washer is .625 inches. Maybe I'm reading your caliper incorrectly?

My WCS has 4700-00023-00 washers on the slingshot plastics (.203 inside diameter, .625 outside diameter and .059 thickness), whereas my BSD has no washer there...

No, you're reading it correctly. I can't answer as to the reason why they aren't listed, unless they were installed by a previous owner. I'll get the warranty card scan to you tomorrow.

Clearly something went wrong with this. Flitz and heavy tumbler use have been key in all of my restores. The results have always been amazing.

#118 8 months ago

About the tumbler, i read you used corn, perhaps try crushed walnut it's more agressive, works for me

Will do, thanks. Just have to find where I put my bottle of Flitz polish. What polishing compound do you add to your tumbler?

I'll give it another go and report back.

#121 8 months ago

First good clean and most of the grime is gone. It looks nice but there are some areas of concern.

Second pass and polish. Looking much better than it did. Shooter lane still needs attention.

A few pictures showing some of the issues of the inserts moving over time and creating fine cracks in the artwork.

#124 8 months ago

You can see the same issue across each insert of the Mist path.

#125 8 months ago

Another around the rats.

#126 8 months ago

Do I have all the parts in the Mist magnet assembly? Or is there something missing? What type of actuator should be on the microswitch beside the drive motor?

Now that I've got this far, do I stick with this playfield or install a new Mirco playfield? Having trouble deciding which way to go with this. I could complete the rebuild, enjoy the game and then sell it with the view to buy a better example. Or go nuts and replace the playfield in this game. Each time I think I've made up my mind which direction to go, I have second thoughts. If the cabinet was in better condition I would go all out.

That's a hard choice indeed. I think the playfield looks quite good (the inserts are quite a common issue, but I don't think it'll be a big problem unless the game will see intense play?).
You can also install a new playfield, and find another game with a good cabinet and change the playfields and sell that other game.

#130 8 months ago

If pf was trashed id deffo go new but it actually looks quite good, unless your wanting to turn this into an absolute mint restore where everything gets replated/ replaced etc... id keep with that pf it does not look bad at all.

#131 8 months ago

id also give the tumbler another go as the results can be amazing with zero work on your part really shine an up look better then new

#132 8 months ago

Continue with it. I wouldn’t worry about those small insert moves. You don’t seem to have the common shooter lane drop wear. My recent acquisition is down to wood there and a similar condition around the inserts. What did you polish up the Playfield with that’s come up nice

#133 8 months ago

I would keep the playfield. It looks very good.

#134 8 months ago

Thanks for the comments and opinions. At this stage I'm leaning towards putting this one back together and then decide whether to trade up.

I used a kit like this and some polishing compound. Just like the old Treasure Cove kits.

As soon as I find my stash of Flitz polish I'll give the tumbler another go.

Very good its really worth a second chance , make sure you use clean media (use walnut for cleaning or corncob for polishing)

Haven't updated in over a week. Lots of cleaning and rebuilding of mechanisms with new coil sleeves and other bits and pieces.

Can you believe after all the parts I ordered in the last few weeks I forgot to order new flipper coils! Ah well, they'll be more parts needed before I'm done.

Don't forget to bend the contacts out to add more tension, better connectivity.

Whole lot of parts ready to be installed when the time comes. Had to buy a complete single drop target mech as the original was long gone

Last few and then all placed into a storage tub until the time comes to start the reassembly process.

Wiring harness removed from the plastic backbox clips and separated. Some connectors will need replacing.

These were the only boards included with the machine. Filthy, although they should clean up ok. I've never come across a CPU with so many chips replaced, at least the repairer took the time to install sockets.

CPU board clean and ready to install. It will be interesting to see if it boots and if it has any faults. First I will need to clean the flux off the rear of the board from the sockets that have been installed and remove the battery holder.
