When I had all the socketed IC's removed, took the time to clean the legs with a pencil eraser. Unfortunately the legs on the YAMAHA sound chip were very fragile and during the cleaning process I broke one of them off when straightening it up. Hope these are still available or I'll have to attempt to salvage it using a header socket.

Here's an example of the result you'll get from Evaporust when the item you start with has a good coating of rust that has eaten through the plating.
On my list to learn sometime in the future is how to nickle plate metal, unfortunately I doubt it will be during this project. So many parts and unique mechs could be saved, rather than replaced. Hopefully someone will start a step by step thread on how it's best achieved.
The knocker bracket and backbox lip catch plate. Both had a good coating of rust before entering the tub of magic liquid.

Quoted from Pinballer73:Anyone know if new clear coffin covers are available? This one has a number of stress cracks at the mounting points.[quoted image][quoted image]
PPS might still have them .

Thanks Molly, yep they do at $25.
Quoted from russdx:how do you clean your pcbs?
thanks
Remove all the socketed chips. Half fill the sink with warm water, quickly dunk the board then use a soft bristle toothbrush with some mild hand soap. Rinse off with warm water, shake lightly then dry off in the sun. Hair dryer or light compressed air over each item. Has worked well for me over many years.

Ah cool, i have put light boards in the dish washer then dried / compress air after. But never like a processor board. I guess long as its 100% dry it will be fine. Does water get into relays etc...
If there is any item on the board that is not sealed, like a relay etc, water will definitely get in and cause trouble. Either remove it, clean carefully or find another method to clean the board.
A friend in the USA showed me a board cleaner in action one day, in an aerosol can. Simply amazing stuff, spray it on a vertical board and all the grime simply ran off. He hosed the board to rinse it, blew it off with compressed air then left to dry in the sun. Can't remember the name of the stuff, it was in a red can if memory serves me correctly.
Quoted from Pinballer73:Might have been this stuff.[quoted image]
Very interesting, iv used foam cleaner in the past which has simular result of all the grime just runs off.
Τρίκαλα
Quoted from Bryan_Kelly:Your pop bumper coil mechs are made up of the wrong parts. Here's a pic of mine before tear down.[quoted image]
Thanks Bryan, I'll check them out in morning. Do you have any plastics left for this game?
Quoted from provato:Nice job!
Why remove the battery holder? Just install batteries that do not leak (Ni-Mh or lithium).
Are you going to install Nvram?
Mainly just to avoid the tempation of installing batteries on the board. I might look at the NVRAM option as well, however not being able to keep the correct time and date is a downside, midnight madness features don't trigger at the right time.

Quoted from KJS:Thanks for all the detail Stu...I am about 4 weeks behind you! Only starting with a populated playfield though. The pictures are great. I'm enjoying the detail you are explaining a lot! I will have plastics and parts left over if you need any. Kurt[quoted image]
Thanks Kurt, definitely interested in what parts you will have available.
Good luck with your rebuild. I have heaps more to add to this thread, just have to find time to upload the photos.
Cabinet stripped of everything other than the ground braid and threaded leg brackets. Vacuumed, then cleaned down. Transformer will need a good clean and paint before being bolted back into place ready for service. Considering sanding back the inside of the cabinet and repainting, but that will have to wait until the weather improves.20190729_132747 (resized).jpg
