Using boiled linseed oil (mahogany)
Instruments- discuss specific features, luthiers, instrument problems & questions
On the website, entitled "Luthiers Mercantile International", I did find the following info:
- If you are working with minimal equipment and working space (possibly a small area or table in your home) your instrument can be effectively finished by either brushing water-based lacquer, French polishing shellac, or wiping on an oil varnish. Each of these finishes is non-hazardous and can be safely applied in your home with no more equipment than brushes or cotton cloths. The oil is the absolute easiest to apply, brushing the water-based lacquer is slightly more involved, and the French polishing requires the most practice and skill. The resulting instrument finish from any one of these materials can range from merely adequate to true professional level depending on your experience and skill.
As far as the tung oil is concerned, I do use Formby's low gloss tung oil finish; which is not 100% pure. I take the surfaces of the dulcimer to 320 grit. I then use a cloth pad to apply 3 to 5 coats, depending on how it is working with the particular wood I am using at the time. I lightly scuff the surface with 320 between coats. Final is with #0000 steel wool and a wax polish.
