[SEL] Babbitt lapping compound

[Elden DuRand]

Rob:

I ran out of layout dye when I quit the machine shop job and went into broadcast engineering (over 40 years ago).  What I've used  since then is magic markers.  Sharpies work nice and the color selection makes sure you won't get hue deprived.

Take care - Elden
