Recent threads prompted me to post this one.
How many of you luthier types have secret building techniques you wouldn't reveal to anyone - even on this forum? Did you develop/discover them yourself or learn them from another master?
A friend who builds banjos and uilleann pipes recently gave me a great tip for doing MOP inlays. I sensed from the way he told it to me that it was more or less a trade secret so I won't reveal it here even though most of you are probably aware of it. I usually rely on Dan Erlewine for handy tips, like the recent one where he fits a small plane iron in a drill press to cut binding mitres.
I'm not asking anyone to reveal their secrets but if you feel like sharing, who am I to stop you. :)
