My spinners get almost no marring from the starter. The ones that seem to get marked up the worst?, the spinners of guys who insist on geting the starter spinning and then jamming it against the spinner.
Plastic spinners are fine.
Dennis-
That's what I meant.
I hand start most of my engines, so it's not even an issue. I almost always use aluminum spinners or spinner nuts on planes that I have to use an electric starter on.
