I need to replace the knuckles on a Samick Grand because they are out of round and the covering is shredded. I am looking for a method that will get the knuckles off cleanly without breaking the shanks yet not take hours. I found several approaches from using a bandsaw. using end cutting pliers and a scraper backing plate for leverage , center pin cutters, heat. I am wondering if someone has discovered a better method perhaps using a jig dremel tool with router bit etc. I have looked at some fret saws used by luthiers to make fine cuts for guitars which might be a slow approach and too inaccurate 

I once saw it done by drilling a hole slightly larger than the knuckle right near the end of the wood so one side is open about the same amount as the width of the knuckle "tang", then putting that in the vice and tapping the knuckle out with a small metal bar slightly narrower than the tang.

Alternately, what about applying a vinegar solution or wallpaper remover and easing it out with pliers?
