Quoted from Pinless:Would it be best to have 2 rotisserie’s to make it easier to transfer parts from the old pf to the new pf?
This is simply not possible, in MANY cases during the swapout, the parts that are removed last have to be installed first. The best thing you can do is take LOTS of pictures and use them in reverse order so you don't install parts that then have to be removed because they block the installation of other parts.
Quoted from Scoot:Lastly, this is a great time to clean and polish everything. I use a variety of cleaning products and polishing compounds but there are a few that will get you the best results. My go to for cleaning everything is Simple Green. It is cheap and works great. For getting rid of rust and corrosion I use Evaporust. All my metal pieces including screws, nuts, etc go into a bowl of this stuff. It will make old rusty or corroded parts look new again. And for polishing I use Flitz. This is amazing stuff for bringing out the shine on metal parts. I take all my stand up posts, wire forms, screw heads, and other metal parts that show on the top of the playfield, and polish them. All the metal posts I put in a drill and run it through a rag with a dab of Flitz. In a matter of seconds, you will have a super polished metal posts or screw heads that will look better than new.
This is likely your best and only opportunity to do this. An emery flap wheel will do wonders at removing all of the ball marks from your stainless steel ball guides.
You also may want to take a look at the STTNG owners forum https://pinside.com/pinball/forum/forum/clubs-members-only there is a lot of good information here as well as some game mods you may want to be interested in performing during the reassembly; for example, if you are even thinking of changing your pop bumper color, this is the best time to do this as the lighting connectors run through every part of the pop bumper assembly and are stapled to the underside of the playfield. When I did mine, I just purchased new pop bumper assemblies https://www.pinballlife.com/williamsbally-pop-bumper-assembly.html in the color I wanted for $47 each rather than spending my time rebuilding them.
