its likely no one here has experience with this, but TB is always a good place to go for luthierie questions. im planning on fretting a guitar (and later a bass) to a certain microtonal scale, and i need a way to slot fretlets, like in this picture: http://www.organicdesign.org/peterson/guitars/ji_mugshot_big.jpg im not interested in the bent frets (and i have absolutely no clue how they do that), but i gotta have the fretlets. my first option is to cut all the way across the board with a slotting saw, put in the fretlet, and then put filler in the unused places. but that sounds pretty messy. so is there any tool that can cut these kind of slots? a hand tool would be prefered, i dont have much of a budget for this. as for power tools, i have a dremel and a plunge router.
