First off, sorry if this question has been asked a million times - I AM reading, but there's a lot to digest!
I’ve recently gotten my dad's old pinball machine (Gottleib EM - #snow-derby) to my house, and want to get it back into playable condition. It worked when I was growing up, but hasn't been turned on in 10+ years and may be closer to 20 since it's been working.
I'm not afraid to get my hands dirty, and can typically follow many basic repair guides, but don't have a ton of experience with electronics and not great with a soldering gun. Can't really read a schematic (though I do have them for my machine).
I don't mind giving it a go, but since this machine does have a bit of sentimental value, I wouldn't want to risk permanently damaging it. It looks like it’s in worse shape than I remember, so not sure exactly where to begin. The playfield has a lot of ‘grit’ on it - not sure what it’s even from. What’s a good gentle cleaner I can use that won’t further damage it? Pictures attached and I know I’ll have lots more questions as I dig in. I have ordered a ring kit (rubber is all dried out and at some point someone tried just using rubber bands to replace one). Would a flipper rebuild kit be needed, too?
The playfield glass also has a good size chip in it - what are the thoughts on replacing that glass with plexiglass? Would it get scratched too easily?
Finally, my wife has asked if there were any lead paints used on these machines that we should be worried about?
Is the "Routine Maintenance" portion of this guide a good place to start? https://homepinballrepair.com/pinball-repair-introduction/#routinemaintenance … or is there a guide that’s more focused on a complete restoration?
Really just looking for some advice on how to get started and hopefully avoid some common mistakes.
