here are two special tools i used to work on the machine.

the one with the black handle is a contact burnisher. it removes oxides and corrosion from switch contacts without damaging the plating layer (unlike sandpaper).

the other tool is a switch adjuster. you slide it over the metal contact tongue and twist it to adjust the alignment.

@tubetime oh wow I haven’t heard of a contact burnished (vs high-grit sandpaper). I looked up a little info on them and sounds like it’s the same idea as sandpaper though? You can still scrape through plating past the oxidation?

What am I missing, is the burnished just a lot more gentle than even 2000 or 4000-grit sandpaper? So maybe you could damage plating but unlikely?

Or a totally different sense of all this?

@zackstern yes sandpaper tends to remove too much, too quickly. i guess you could use a fine grit, but a burnisher is easier to manipulate between the contacts.

I was just taught to use a strip of paper. Works really well.
