I have rubbed down the trailing edges of my foils gently with 800 grit wet and dry and they are still humming. I would be forever grateful if someone could spell it out to me what I need to do for sharper and straighter trailing edges.
Wet and dry? Grits? Sandpapering? How long for etc.
I'm afraid I don't have the knowledge to answer your question but maybe this thread http://www.laserforum.org/showthread.php?t=9036&highlight=humming might. There is a quite specific answer post #14 by Clive Humphris that sounds like a knowledgeable/specific one.
