Anybody know anything about polishing metal coin slots on Midway coin door?

[rackoon]

I got an awesome bally midway coin door about 5 month ago off eBay and its in almost perfect condition except the polished steel coin slots are slightly pitted with rust. I'm pretty sure its polished steel and not chrome but I could be wrong.

I want to take them off and buff them or something. Does anyone know anything about how to go about this?

If they're pitted, then you need to buff the pits out first.....  Use a Dremel Tool with a sanding pad and 800 to 1000 grit paper first.... Then buff them up using the dremel and a polishing pad with some very fine polishing paste to take out the sanding marks. Finish up with a another polishing pad and some wax polish which will protect the surface or else give them a coat of clear lacquer.

This is of course assuming that they are plain steel and not chrome plated. If they're chrome plated, then just take them to a local Electro plating company and ask them to quote you to sand blast and re-chrome them.

Also, you have to widen the coin slots a smidge if you want them to accept tokens.  If you're gonna do this, do it before you get them re-chromed.

I have two questions.

First, if by chance they were chrome, how would I know? I don't see any flaking plus, I think it would be a bad choice for them to make it chrome plated because it would wear off with all those coins rubbing against them.

Second, does anyone have the measurements of a token so I can grind or file out the coin slots.

flaking only happens with very very poor quality chrome plate, which has been applied badly.

plus, I think it would be a bad choice for them to make it chrome plated because it would wear off with all those coins rubbing against them.

Chrome is harder than steel!! a lot of automotive components are chrome plated to make the surface harder! Things like kingpins are often plated.

Good chrome is very hard wearing. It'll take 30 years to rub away the chrome from a coin slot entrance, especially in a domestic environment.

...............except the polished steel coin slots are slightly pitted with rust..........

Leave the coindoor in some rust converter overnight, and then give it a polish afterwards with metal polish and see how it comes up before takeing it off to get rechromed.  It may be all it needs and if so, it will save alot of cash.

Also, use a sealable container when you drown the part in rust converter. Make sure you use a bit more than you need because many/all rust converters evaporate (sealable container considerably slows the evaporation) leaveing an oxide coating on your part as it evaporates dry (its often/always hard to get the oxide off too).

The coindoor might polish up nicely with a rag and metal polish if you dont have a machine buff.

Oh, and avoid leaveing anything thats not steel (aluminium comes to mind ) in rust converter just incase.

Does any one out there know for sure what metal is on the Baily midway coin slot. I'm starting to think its polished steel because if I look real close I can see small dents and dings from coins and it looks like the same material all the way through. It also has a slight rough texture to it if one looks close to it. I'm not sure if you can do that with chrome.

The ones on my Gorf cab are polished steel, seems likely that other Midway cabs would be, as well.

Most tokens (including Santoro's) are .984 of an inch, I believe.  You can always go get one from Chuck E. Cheese to test with..
