I didn't have any spare tuners laying around, so I thought I'd try an idea using eye bolts in the same manner as my old Steinberger headless guitar. Instead of wrapping the string around a post, the string is looped onto the eyebolt and then tuning is done by tightening the nut at the end of the headstock, thus tightening the string. I wanted to use wingnuts, but there wasn't enough room. It's kind of a pain having to pull out my needle nose pliers every time I have to retune, but it's really no worse than the zither pins on my celtic shepherd's harp. And once the strings are in tune, they tend to stay that way.
