Hi guys, I'm working on building a maple neck with an aluminum fretless fretboard. I did a little research on getting the aluminum to stick to the neck blank, and used a very expensive marine grade epoxy to glue it up. It seemed really strong, at least at first - but as I was cutting the nut slot the entire fretboard just fell right off! Back to the drawing board... Upon further research I've discovered that many say the aluminum needs to be chemically treated before gluing, while others say some metal specific epoxies can be used - but none say anything about actually bonding aluminum to wood, only metal to metal bonding. Have any of you guys tried such a thing? How should I go about getting my fretboard to stay bonded to a maple neck? Any ideas?
