Most dulcimer makers fret the fingerboard before gluing it to the soundboard, and then glue the soundboard to the rest of the dulcimer.
There is a good reason for this; it is much easier than fretting the fingerboard on the finished dulcimer, and many dulcimer makers get good results this way. I found I often get acceptable results when I’ve tried this, but sometimes, the fingerboard is no longer exactly as I want it to be. Wood tends to remember it was once a tree and likes to move a bit long after the end of its life, and by the time I have started putting finish on the dulcimer, anything that might move, has moved.
I only know of a few other dulcimer makers who fret after the dulcimer is assembled, and all have said they do it for the same reason; it assures the fretboard will be perfect and never just good enough.
Here are the tools I use when preparing a fingerboard; a straight edge, a level used as a sanding beam, a scraper, a square, a feeler gauge, and a four-sided sanding block with four different grits.
When checking the fingerboard on this dulcimer, everything was just as I like it from the get-go, and because I’m a vegetarian, I made a burnt offering of lentils and broccoli to the Dulcimer Gods to show my appreciation.
On this dulcimer, the fingerboard was close but not quite the way I want it to be, so I used a scraper to level a high spot and add some relief from around the 2nd fret to the 7th fret. I use approximately .002″ of relief so low action won’t cause buzzing and rattling of the strings against the frets in the lower positions. I check the work as I go with the straightedge and feeler gauge.
In a situation when things are just too wonky, I use the level as a sanding beam to assure a flat fingerboard from end-to-end before adding the relief.
The last step is to sand using all four grits on the four-sided sanding bock to even out any subtle irregularities left by the scraper and to prepare the fingerboard for finishing.
As a final step, I use the square to make sure the fingerboard is flat across its width. It almost always is, but I will always remember the one time I didn’t check before putting in the frets!
All this work is done before I apply the last coat of finish to the dulcimer, or if I’m feeling brave, before the last coat is rubbed out. This way, if I accidentally create a little scratch somewhere, I have not yet past the point of no return for making it go away.
Here’s the fingerboard after a light wipe down with oil. Next come the frets!
As I mentioned in another post, since starting this blog in 2007, some of the titles of my posts can be a bit repetitive, but my methods of work are always changing, so there is usually something new in the content, or at least I hope there is!
Thanks for stopping by and visiting. I tend to post photos of work in progress on Instagram more frequently than I do here.
