Cleaning the playfield mechanics
I’ve spent the past few days cleaning the playfield mechanics, which meant taking them all apart, cleaning the bits and assembling them again.
As an experiment, I sanded the diverter blade down to 600 grit (as with the lockbar) and was very happy with the result. It gives a mirror-like surface with fine horizontal scratches, which I like. I now plan to sand all exposed stainless steel parts down to 600 grit.
