A question about intonating a dulcimer
Instruments- discuss specific features, luthiers, instrument problems & questions
You want to angle the slot so that the high point is on the bridge side to preserve the VSL.
Does this apply to a string spacer and a zero fret?
Mike, the nice thing about cutting the slots in the string spacer is that it's nearly impossible to cut them too deep, the only issue could be if you cut them too wide. I would definitely do that before anything else, since it's the most likely issue and also the easiest to fix. Put a couple layers of painters tape over the wood before you start filing, to avoid any accidental damage to the wood.
I am guessing that string spacer was added after the fact by someone who believed they were replacing a nut. I saw a few photos online of other dulcimers from the same company, and their string spacers look pretty different than this one. As others have mentioned, the "zero fret" acts as the nut, and that piece of plastic should just serve to keep the strings the correct distance apart, which is why you should be careful not to make the slots any wider, since that could affect the distance between the strings.
