I've got an SX fretless neck that I've been working on. I was filing down some protruding fretline inserts last night and I noticed that several are loose. That got me to thinking that I could replace the plastic inserts with some ebony veneer that I have left over from my last defretting project. The neck has no position markers, so the ebony fretlines would make for a nice 'stealth' look. The only problem is that I can't figure out how to get the fretlines out. I'm afraid that heat will tattoo the board, possibly weaken the fingerboard/neck glue joint, and make a general mess if the makers start to melt. I've thought about sawing them out, but I don't want to expand the slots. Any ideas? The inserts are glued in, so I don't think I could just tap them out from the sides. Maybe I could get under them with a mini screwdriver and pry them up? Has anyone done this before?
