Adding frets

Postby jbonn » Fri May 15, 2009 9:16 am

A friend wants me to add 1 1/2 and 8 1/2 frets to his dulcimer. It has a 27" scale. How do I figure the placement of these? Also, any suggestions on the best way to cut them on an existing instrument. Thanks for any help.

Use a fretscale calculator such as WFret. Measure the exact VSL, to the nearest 1/100th of an inch or less and plug that number into the calculator. Or else use a faux fret wire and your electronic tuner to "sound" the right location and mark it. When marking to cut, measure from the crown of the previous fret, not it's edge. Cut using a fretsaw.

Ken, Ive been thinking about your response and have a few questions. I've used wfret before, but how would I add the 1 1/2 and 8 1/2 frets to it? Would splitting the distance between 1 and 2 and 8 and 9 work? In any case, before I pick up a saw I'll double check with your faux fret idea. I liked that. Thanks again.

The newest version of WFret is, unfortunately IMHO, only fully chromatic these days. No specifying "diatonic". So ALL the "half" frets are there!!

Asuming the string is open D the first fret will be an E and the second fret is F#. adding a 1+ fret between those 2 in the right spot gives you an F natural. The 8+ will give you an F in the next octave. For a different tuning the same applys but the actual notes will be different.

With that info and a tuner it becomes a simple matter to locate them on a MD that is already fretted. Just tune the string open DEAD on then use a tooth pick as a tempory fret and position it where you get the F. Mark the spot and simply slot the fretboard and add the frets.

Thanks a lot. Between yours and Ken's help this shouldn't be that hard.
