And let's continue story. Machine is already done so now it's possible to report little faster pace than normally during restoration :) And don't let funny posting times fool you, we have "little" time difference comparing to Australia (GMT+2).
Target banks
Drop down targets were quite messy, as you did saw in earlier post. Naturally whole assembly was quite mess. It was disassembled fully and cleaned. All suitable parts (=small enough) were first washed on ultrasonic cleaner with some 55 celsius water and some local cleaning stuff, pH 10,5. Most of flipperdust was removed but still lots to do. I usually after this treatment still go through all parts by hand with sponge and Novus2. It gives nice touch to metal surfaces and removes stains that didn't came of in ultrasonic cleaner. Dropdown targets needed to sand a little bit, there was quite nasty marks in shafts and I wanted those to be as smooth as possible to ensure good operation for future. So 600 - 1000 - 1500 grit sandpaper treatment to all 14 targets. After that I installed new decals that my friend made from sample that I provided, it's printed and cutted to some vinylpaper with adhesive and surface is hot laminated. Same method and stuff is used outdoos signs that their company makes. So those should be quite UV resistant and be able to take lots of hits without damage. Anyhow, that is not so big problem, if some targets starts to have some marks, I can easily replace those, I have some 100 extra copies for future :) And no mylar etc. is needed afterwards. After new decals was installed, I waxed all targets and metal parts through with Carnauba-vax. Also coils were cleaned, plungers polished, new coil sleeves installed etc. Before coils didn't even return to down-position after bank reset, now everything worked like charm. And some pictures to follow. Story continues in next post.
