- In this episode I will route the two soundholes into the soundboard using a dremel tool with a little modified circle jig. The soundboard is then glued onto the rest of the instrument. I decided to leave the soundholes open and clean rather than decorating them. I might in the futurer add a rosette to them. The soundboard is then polished with shellac. As it is my first time using shellac I decided to buy a ready to use mix - however I do not recommend this, in future builds I will definitely mix my own shellac. The result is still very pleasing to me, the smell of shellac when being applied is a great joy. The rest of the instrument is oiled with a couple of coats of boiled linseed oil. I wasn´t sure wether oiling the pinblocks is a smart idea as the tuning pins must not be lubricated, but linseed oil polimerizes to a solid surface, and so the tuning pins should be fine. The oil I am using is complemented with a hardener to avoid long hardening time.
For some parts of the build I will be referencing the book "Saiteninstrumente selbst gebaut Band 1" by Martin Kesselring (Zytglogge Verlag Bern, 1987)

So cool! Must feel great to have accomplished your own instrument!
yess handcrafting a musical instrument and slowley realizing that it starts resonating is an amazing experience. highly recommended!
Thanks for the fantastic video, the instrument looks beautiful and your craftsmanship is very impressive. I am also building a dulcimer at the moment and interested in your use of linseed oil on the pin block, you mention it polymérises. I have used danish oil for lever harps it’s easy just takes a long time, do you know if danish oil behaves the same way, could it be used on pin blocks? There are at least twice the pins on a dulcimer as a harp, so it could be risky....
hey tal, sorry for the late reply. so with oil finish you just want to be careful, as it might affect the grip of the pin inside the pinholes. i confirmed the oil i used with a friend who is a piano technician and he suggested longterm testing because of that reason. the finish on my instrument has fully cured by now and i am very pleased with the result. i cannot find any negative effect on the tuning or the stability... however i have not tried any other finished yet. let me know what you ended up doing!
@@solitudewoodworking8431 thanks for answering.. I decided not to risk things and ended up using polyurethane varnish, the mahogany sound board goes over the pin blocks so I used colored grain filler then several thin coats of satin polyurethane varnish, I am really happy with how it turned out, especially the way the light plays off the strings reflecting onto the wood grain :). I will continue to use danish oil on my harps as the tuning pins are larger and the oil nicely evens the colour of the European Walnut I use, as you suggest I need to apply carefully around any holes and allow to cure fully before adding hardware.
Amazing! will you make dampers for it also?
I might add some in the future, but for now I will go without. Do you think they will be necessary?
@@solitudewoodworking8431 No, it was just wondering. I never seen how to make them in detail.
